  • Gas inlet with stainless steel capillary and inlet valve

ThermoStar® GSD 350 T

Select the smallest mass range with which the set measuring tasks can be performed. This ensures maximum sensitivity.
  • Gas inlet with quartz capillary, continuously open

The next generation in efficient solution for gas analysis. Intelligent software. Easy operation. Compact design. Customization possible.

Today, mass spectrometry is one of the most widely used analytical methods for identifying chemical elements and compounds. With the OmniStar and ThermoStar benchtop analysis systems, Pfeiffer Vacuum offers you two optimum complete solutions for gas analysis, in particular in connection with chemical processes, in the semiconductor industry, metallurgy, fermentation, catalysis, freeze drying and environmental analysis.

The OmniStar and ThermoStar analysis systems consist of inlet system, PrismaPro mass spectrometer, a dry-compressing MVP diaphragm vacuum pump and HiPace turbopump. They feature a heated, temperature-regulated gas inlet system and, by comparison with such competing methods as FTIR and IR, are suitable for qualitative and quantitative analysis of gases. The gas inlet is quipped with a capillary that can be heated to 350°C; this capillary is made of stainless steel in the OmniStar and of quartz glass in the ThermoStar. The heated capillary prevents vapors from condensing during analysis of the sample gas. This 2-stage inlet enables a quasi segregation-free gas supply.
