The Extrel atmospheric pressure ionization mass Spectrometer (APIMS) was designed to have consistent, reliable, low parts per trillion detection limits for gas contaminates. The VeraSpec Trace system has been the preferred choice for ultra high purity (UHP) gas contamination analysis and trace pollution studies for more than twenty-five years.
The VeraSpec™ Trace has been developed around the high transmission 19 mm quadrupole mass filter and combined with the proven DC Corona Discharge source for maximum sensitivity. It is available with a number of mass ranges from 1 to 4000 amu to fit the specific application.
The key features of the VeraSpec Trace System are:
- The EI system is taken from Extrel's MAX300 Industrial mass spectrometers and has the same proven performance available on those systems with detection limits in the low ppb range.
- The system uses a 19mm tri-filter quadrupole and is available in several mass ranges.
- The system is also offered in an MS/MS configuration, the VeraSpec Trace MS/MS. The VeraSpec Trace DS is the dual source model with both an API and Extrel's decidedly capable closed source EI ionizer with a capillary inlet in the standard configuration.
- Source selection is possible using Extrel's large deflector for maximum flexibility and sensitivity. Adding a membrane inlet to the EI system pushes the detection limits for applicable analytes into the sub-ppb range in the VeraSpec Trace DS-MIMS system.
