Report of sample preparation, sub-sampling and analysis
Reference: Material: Metal Cylinder Catalytic Converters
SGS Reference Numbers: - Precious Metals Analysis - Physical Dimensions & Cell Density
Page 1 of 166 total pages -----------------------------------
1. General Information
1.1 At the request of Jackie Wang from T aotao, SGS was approached to analyse one catalytic converter from an unknown model of vehicle from Taotao USA Inc.to determine their precious metals content.
1.2 Through communications, the following measurements were also requested: piece weight, length, diameter, loading and cells per square inch.
1.3 The sample preparation and sub-sampling was performed using the sampling method supplied by SGS (see Appendix One). The precious metals analysis was performed using the peroxide fusion method from SGS (see Appendix One).
1.4 Calculations for metal loading on the catalytic converter parts were performed using information supplied by the EPA (see Appendix Two).
2. The sample was couriered to the SGS laboratory in Lakefield, Ontario, Canada. SGS can make no guarantees or warranties as to whether the sample was unaltered before it was delivered to our site.

Sampling and Precious Metals Analysis

SGS Sampling Method:
Small Motorcycle, ATV or Cart System converters are analyzed at our SGS laboratory in Lakefield, Ontario. These cylinder sleeves are prepared in the following manner as there has been no industry standard protocol as to how they should be prepared and sampled. The following has been used by our clients with very high degree to success.
A 3/8-inch high speed drill running at a slow RPM drills four holes, one in each quarter of the converter, complete through from one end to the other (see diagram below). All material generated is captured in a catch basin placed below the converter during drilling. Once drilling is complete, the entire sub sample is then placed in a container. Pieces of metal mesh are removed from the sub-sample using a magnet and reserved. The remaining material is pulverized as well as possible, knowing that there could still be pieces of the metal mesh present.
This sample is then sent to our precious metals laboratory where it is sub sampled 3 times as explained in the enclosed 13peroxideAAS.pdf document. If there is a large outlier between the triplicate analysis results, a fourth portion is analyzed.
This is the best method we have developed to date as we have had discussions with clients on this matter.

Agreed Test Plan for SGS/Taotao
Catalyst Testing:
Page 4 of 16
The test plan must -Specify that information of each catalytic converter that is the subject of testing and inspection will be collected and reported to Taotao.
1. Weigh entire sample at start (the intact casing, honeycomb mesh interior, and washcoat amount inside); measure the diameter of the mesh and cell density
2. Do the coring & collect core samples and washcoat (as discussed on our recent call, include a method for preventing excess washcoat from falling out of other parts of the honeycomb during the drilling process)
3. Weigh the core samples and washcoat; set aside for now 4. Weigh the remaining casing, washcoat, and mesh (now missing X number of cores) -
this is not required, but could be useful in observing loss 5. Remove the casing from the remaining mesh; separate these pieces; measure the
length of the honeycomb mesh 6. Clean the casing : scrape any washcoat powder or small mesh pieces out; put those
with the remaining mesh 7. Weigh the clean casing 8. Weigh the mesh and washcoat remaining after removing the casing 9. Return to the core samples of mesh and washcoat collected in coring; tear apart the
core samples and remove all washcoat in cores 10. Use a magnet to separate the mesh core pieces from the collected washcoat; weigh
the washcoat 11 . Choose a needed portion of the washcoat to analyze; determine the ppm or mg/kg of
the platinum group element(s) in the washcoat 12. Add the weight from #3 to #8, this is the total weight of honeycomb mesh and
washcoat in the sample 13. Back estimate the total amount of washcoat in the catalytic converter: multiply the
weight from #12 by the weight from #10 and divide that by the weight from #3, this will yield an estimated amount of washcoat in the honeycomb mesh for the entire sample
14. Determine the weight of platinum group element in the catalytic converter by multiplying the concentration from # 11 to the estimated amount of washcoat from #13 (include weight conversions mg, g, kg)
15. Use the measurements from #1 and #5 to calculate the volume of the honeycomb mesh (pi xR2x H); use for loading calculations (g/L)

Agreed Test Plan for SGS/Taotao
Catalyst Testing:
Page 7 of 15
The test plan must -Specify that information of each catalytic converter that is the subject of testing and inspection will be collected and reported to Taotao.
1. Weigh entire sample at start (the intact casing, honeycomb mesh interior, and washcoat amount inside); measure the diameter of the mesh and cell density
2. Do the coring & collect core samples and washcoat (as discussed on our recent call , include a method for preventing excess washcoat from falling out of other parts of the honeycomb during the drilling process)
3. Weigh the core samples and washcoat; set aside for now 4. Weigh the remaining casing, washcoat, and mesh (now missing X number of cores) -
this is not required, but could be useful in observing loss 5. Remove the casing from the remaining mesh; separate these pieces; measure the
length of the honeycomb mesh 6. Clean the casing: scrape any washcoat powder or small mesh pieces out; put those
with the remaining mesh 7. Weigh the clean casing 8. Weigh the mesh and washcoat remaining after removing the casing 9. Return to the core samples of mesh and washcoat collected in coring; tear apart the
core samples and remove all washcoat in cores 10. Use a magnet to separate the mesh core pieces from the collected washcoat; weigh
the washcoat 11. Choose a needed portion of the washcoat to analyze; determine the ppm or mg/kg of
the platinum group element(s) in the washcoat 12. Add the weight from #3 to #8, this is the total weight of honeycomb mesh and
washcoat in the sample 13. Back estimate the total amount of washcoat in the catalytic converter: multiply the
weight from #12 by the weight from #10 and divide that by the weight from #3, this will yield an estimated amount of washcoat in the honeycomb mesh for the entire sample
14. Determine the weight of platinum group element In the catalytic converter by multiplying the concentration from #11 to the estimated amount of washcoat from #13 (include weight conversions mg, g, kg)
15. Use the measurements from #1 and #5 to calculate the volume of the honeycomb mesh {pi xA2x H); use for loading calculations {g/L)

Sampling and Precious Metals Analysis
Pago 3ot 15
SGS Sampling Method:
Small Motorcycle, ATV or Cart System converters are analyzed at our SGS laboratory in Lakefield, Ontario. These cylinder sleeves are prepared in the following manner as there has been no industry standard protocol as to how they should be prepared and sampled. The following has been used by our clients with very high degree to success.
A 3/8-inch high speed drill running at a slow RPM drills four holes, one in each quarter of th13 converter, complete through from one end to the other (see diagram below). All material generated is captured in a catch basin placed below the converter during drilling. Once drilling is complete, the entire sub sample is then placed in a container. Pieces of metal mesh are removed from the sub-sample using a magnet and reserved. The remaining material is pulverized as well as possible, knowing that there could still be pieces of the metal mesh present.
This sample is then sent to our precious metals laboratory where it Is sub sampled 3 times as explained in the enclosed 13peroxideAAS.pdf document. If there is a large outlier between the triplicate analysis results, a fourth portion is analyzed.
This is the best method we have developed to date as we have had discussions with clients on this matter.

Report of sample preparation, sub-sampling and analysis
Reference: Material : Metal Cylinder Catalytic Converters
SGS Reference Numbers: - Precious Metals Analysis - Physical Dimensions & Cell Density
Page 1 of 14 total pages
1. General Information
1.1 At the request of Jackie Wang from Taotao, SGS was approached to analyse one catalytic converter from an unknown model of vehicle from T aotao USA Inc.to determine their precious metals content.
1 .2 Through communications, the following measurements were also requested: piece weight, length, diameter, loading and cells per square inch.
1 .3 The sample preparation and sub-sampling was performed using the sampling method supplied by SGS (see Appendix One). The precious metals analysis was performed using the peroxide fusion method from SGS (see Appendix One).
1 .4 Calculations for metal loading on the catalytic converter parts were performed using information supplied by the EPA (see Appendix Two).
2. The sample was couriered to the SGS laboratory in Lakefield, Ontario, Canada. SGS can make no guarantees or warranties as to whether the sample was unaltered before it was delivered to our site.

Sampling and Precious Metals Analysis
Page 3 of 14
SGS Sampling Method:
Small Motorcycle, ATV or Cart System converters are analyzed at our SGS laboratory in Lakefield, Ontario. These cylinder sleeves are prepared in the following manner as there has been no industry standard protocol as to how they should be prepared and sampled. The following has been used by our clients with very high degree to success.
A 3/8-inch high speed drill running at a slow RPM drills four holes, one in each quarter of the converter, complete through from one end to the other (see diagram below). All material generated is captured in a catch basin placed below the converter during drilling. Once drilling is complete, the entire sub sample is then placed in a container. Pieces of metal mesh are removed from the sub-sample using a magnet and reserved. The remaining material is pulverized as well as possible, knowing that there could still be pieces of the metal mesh present.
This sample is then sent to our precious metals laboratory where it is sub sampled 3 times as explained in the enclosed 13peroxideAAS.pdf document. If there is a large outlier between the triplicate analysis results, a fourth portion is analyzed.
This is the best method we have developed to date as we have had discussions with clients on this matter.

1. Parameter(s) measured, unlt(s): Rhodium (Rh), Platinum (Pt), Palladium (Pd) in %
2. Typical sample size: 0.25-3.0 g
3. Type of sample applicable (media): Automobile and petroleum catalysts
4. Sample preparation technique used: The sample is fused using sodium peroxide at approximately 700°C .The melt is dissolved in water, and acidified with HCI. Tellurium is added followed by stannous chloride addition. The tellurium and precious metal precipitate is filtered out of the solution, and dissolved in aqua regia.
5. Method of analysis used: Flame atomic absorption spectrometry (AAS) using acid matrix matched calibration materials.
6. Data reduction by: Computer, on line, data fed to Laboratory Information Management System with secure audit trai l.
7. Figures of Merit: This method has been fully validated for the range of samples typically analyzed. Method validation includes the use of certified reference materials, replicates, duplicates and blanks to calculate accuracy, precision, linearity, range, limit of detection, reporting limit, specificity and measurement uncertainty.
The Reporting Limit has been determined according to the following:

Agreed Test Plan for SGS/Taotao
Catalyst Testing:
Page 7 of 14
The test plan must -Specify that information of each catalytic converter that is the subject of testing and inspection will be collected and reported to Taotao.
1. Weigh entire sample at start (the intact casing, honeycomb mesh interior, and washcoat amount inside); measure the diameter of the mesh and cell density
2. Do the coring & collect core samples and washcoat (as discussed on our recent call, include a method for preventing excess washcoat from falling out of other parts of the honeycomb during the drilling process)
3. Weigh the core samples and washcoat; set aside for now 4. Weigh the remaining casing, washcoat, and mesh (now missing X number of cores) -
this is not required, but could be useful in observing loss 5. Remove the casing from the remaining mesh; separate these pieces ; measure the
length of the honeycomb mesh 6. Clean the casing: scrape any washcoat powder or small mesh pieces out; put those
with the remaining mesh 7. Weigh the clean casing 8. Weigh the mesh and washcoat remaining after removing the casing 9. Return to the core samples of mesh and washcoat collected in coring; tear apart the
core samples and remove all washcoat in cores 10. Use a magnet to separate the mesh core pieces from the collected washcoat; weigh
the washcoat 11. Choose a needed portion of the washcoat to analyze; determine the ppm or mg/kg of
the platinum group element(s) in the washcoat 12. Add the weight from #3 to #8, this is the total weight of honeycomb mesh and
washcoat in the sample 13. Back estimate the total amount of washcoat in the catalytic converter: multiply the
weight from #12 by the weight from #10 and divide that by the weight from #3 , this wlll yield an estimated amount of washcoat in the honeycomb mesh for the entire sample
14. Determine the weight of platinum group element in the catalytic converter by multiplying the concentration from #11 to the estimated amount of washcoat from #13 (include weight conversions mg, g, kg)
15. Use the measurements from #1 and #5 to calculate the volume of the honeycomb mesh (pi xR2x H); use for loading calculations (g/L)
