Advantages of FI

Field Ionization (FI) - An ideal ionization technique for molecular weight determination !

FI ionizes the sample by tunneling electrons from the molecules in the presence of a high electric field.

Carbon emitter

● FI (Field Ionization)A sample vaporized by GC or the standard sample inlet is introduced to the vicinity of the emitter.

A soft ionization technique with minimal fragmentation, FI is ideal for samples that are volatile but easily fragmented with EI or CI.Unlike CI, FI uses no reagent gas ; no need to choose a reagent gas appropriate for the analyte.

PolymersApplication 3

Pyrolysis GC/MS is widely used as an analytical technique for high molecular weight polymers. Instant thermal decomposition makes it a simple yet powerful technique with high reproducibility.

GC/TOFMS, which is capable of acquiring exact-mass results in a single GC/MS analysis, enhances the reliability of library search results. It is also effective for qualitative analysis of peaks that cannot be identified through library search. The system also acquires accurate distribution of isotopes of molecular ions, which is effective in molecular identification.

GCxGC (comprehensive 2D GC)

The AccTOF GCv 4G is capable of ultrahigh separation GCxGC analysis while maintaining ample data points.

GCxGC is a continuous heart-cut system designed to use 2 columns having different polarities, trap the eluted components using a modulator in the 1st column at given intervals, and perform high-speed analysis of the trapped components in the 2nd column. GCxGC is a powerful capillary GC technique that features higher resolution than traditional capillary GC and is capable of high-sensitivity analysis of components by the group. It requires a detector capable of high-speed data acquisition. Because the peak widths of the chromatogram are extremely sharp compared to traditional capillary GC.

N.D

High-resolution TOFMS can reduce the interference from matrix. Peaks from the matrix that are detected at low resolution will be eliminated at high resolution. This high selectivity reduces false positive and allows for more accurate quantitation.

GC/TOFMS detects all components that are ionized. Thus, the operator is freed from the lengthy process of defining analytical conditions such as SIM (Selected Ion Monitoring) and SRM (Selected Reaction Monitoring). Theoretically, there is no limit on the number of components that can be analyzed. The AccuTOF GCv 4G can perform simple simultaneous analysis of multiple components using its unique exact mass database for approximately 350 components (1 quantitative ion and 4 qualitative ions per component, editable).

TOFMS performs high-resolution, high-mass-accuracy analysis over a wide m/z range (m/z 35 to 600) without selecting a measurement mode such as SCAN and SIM. As a result, it allows for acquisition of highly selective chromatograms for all ions observed, demonstrating its superior qualitative capability. The acquired data can be used to analyze non target compounds as well.

The table on the right shows the limit of quantitation and the relative standard deviation of 353 components that were analyzed simultaneously. The results demonstrate superior sensitivity and reproducibility for simultaneous analysis of multiple components

High selectivity at high resolution makes it possible to detect the PCBs contained in an oil sample.

The EICC acquired with the window width set to low resolution (top, equal to QMS) was unable to eliminate the oil interference from the PCB impurities. The high-resolution mass chromatogram (bottom) successfully detected the peaks of pentachlorinated PCBs by eliminating the interference.

Effective use of EI/FI/FD:● EI for qualitative analysis through library search● FI for molecular weight determination● GC/FI for type analysis of hydrocarbon samples● FD for polymer analysis● Accurate mass measurement

The analyzer uses 2 stage acceleration (spatial focusing) and reflectron (energy focusing) to insure stable high-resolution analysis at all times. It also employs oa-TOFMS (orthogonal acceleration time-of-flight MS) for efficient use of ions from the ion source.

Two microchannel plates (MCP) are used to detect ions at high sensitivity. The new patented anode forms a new electric detection circuit, and its superior response enhances the level of sensitivity as well.

Continuous averager free from the problems with conventional TDC - Accurate mass reproducibility without correction -

A new high-speed preamp/data acquisition system is capable of sampling TOFMS signals at 4 giga samples/second, twice faster than the previous model. This enables higher mass-resolving power and higher mass-accuracy analysis.

Two signal processing techniques have been used for TOFMS: TDC (Time-to-Digital Converter) and continuous averager. TDC requires statistical correction, and as a result the mass accuracy is determined by the correction parameters corresponding to the number of ions detected. The AccuTOF GCv 4G uses a continuous averager that is capable of continuous signal accumulation in real time, achieving high mass accuracies without data correction.
