Boric Acid HF Neutralization
Allow vessel to cool. Add 30 ml H3BO3 (4%) into the vessel that contains the sample and acid.
This procedure can be used if it is necessary to complex the residual hydrofluoric acid or redissolve insoluble fluorides formed by reaction ofcertain analytes with hydrofluoric acid.
Alternatively, 1-4g of solid H3BO3 + 25mL deionized H2O can be used in place of the 4% w/v solution.

a) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain the required results onyour sample.b) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.c) The control / reference vessel must contain the largest and most reactive sample.d) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at or below roomtemperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.e) If programming as One Touch, the ramp time and power will be automatically determined based on the number and type of vessels detected.

Boric Acid HF Neutralization
Allow vessel to cool. Add 30 ml H3BO3 (4%) into the vessel that contains the sample and acid.
This procedure can be used if it is necessary to complex the residual hydrofluoric acid or redissolve insoluble fluorides formed by reaction ofcertain analytes with hydrofluoric acid.
Alternatively, 1-4g of solid H3BO3 + 25mL deionized H2O can be used in place of the 4% w/v solution.

Weigh 0.5 g of the sample into the digestion vessel. Add 5 ml of HNO3, 5 ml of HF, and 5 of ml H2O. Gently swirl the mixture and waitapproximately 15 minutes before closing the vessel.
After heating program in step 1, allow vessel to cool before proceeding with step 2.
The addition of Deionized Water may improve solubility of metal alloys.
This procedure uses hydrofluoric acid. If it is necessary to complex the residual hydrofluoric acid or redissolve insoluble fluorides formed, anadditional complexation step with boric acid should be used. This procedure can be found in the One Touch Method note entitled “Boric AcidHF Neutralization”.

US EPA 3015a (Aqueous Samples)
Transfer 45 ml of the sample into the digestion vessel. Add 5 ml of HNO3, or alternatively 4 ml of HNO3 and 1 ml HCl. Gently swirl themixture before closing the vessel.
The addition of Conc. HCl (0-4 ml) is appropriate for the stabilization of Ag, Ba and Sb, and high concentrations of Fe and Al in solution. Theamount of HCl will vary depending on the matrix and the concentration of the analytes. The addition of HCl may, however, limit thetechniques or increase the difficulties of analysis.

This method is intended to be an acid leach, not a total digest. Hydrofluoric acid will be required to provide complete digestion of the samplematrix.
a) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain the required results onyour sample.b) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.c) The control / reference vessel must contain the largest and most reactive sample.d) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at or below roomtemperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.e) If programming as One Touch, the ramp time and power will be automatically determined based on the number and type of vessels detected.
