Conventional GCMS that are using Quadrupole Mass Spectrometers, or Ion Trap Mass Spectrometers, do not provide enough information for a reliable peak reconstruction of very narrow peaks over the full mass range. Quadrupole Mass Spectrometers have limited scanning speed, and limited m/z range. In comparison, Time of Flight Mass Spectrometry (ToF-MS) is capable of unlimited m/z range and with instantaneous (non-scanning) acquisition rate. This makes ToF-MS highly suitable for Ultra-fast GC and GC X GC applications.
The DANI MASTER ToF-MS is a Gas Chromatorgraph with Time-of-Flight Mass Spectrometer detector that performs the fastest acquisition rates (1000 spectra/s) and the widest linear dynamic range (105) available on the market. These capabilities are offered in an extremely compact bench-top instrument.
The DANI MASTER ToF-MS constantly acquires 30,000 mass spectra over the entire mass range compared to the fastest quadrupole Mass Spectrometer which only provides about 10 mass spectra at 10,000 amu/s in the same mass range (1-1,000 amu).
All spectra acquired are stored in a compressed format to provide a continuous full mass range acquisition rate selectable up to 1000 Hz written to disk.
In addition, the system offers an outstanding dynamic range with a linearity of 5 orders of magnitude, remarkably reducing sample preparation steps, e.g. dilutions and concentrations, as well as the number of analyses.
The MASTER LAB software offers reliable control of the system, from auto-tuning procedures to GC and sample sequence management. It also provides a powerful data processing solution and an original de-convolution algorithm capable of handling the large amount of information resulting in a reliable identification of trace compounds even in complex matrices.
