Many modern industrial uses of specialty gases require very high purities to ensure that – among other reasons – yields are high, catalysts are not poisoned, and equipment is not damaged or subject to frequent maintenance.
In this web seminar, we introduce selected ion flow tube mass spectrometry (SIFT-MS), a form of direct mass spectrometry that provides real-time detection of a wide range of volatile organic compounds and many inorganic gases to sub-part-per-billion concentrations (by volume; ppbv). Applications of SIFT-MS to diverse process and specialty gas applications will be described, including:
- Reactive electronic gases
- Impurities in beverage-grade carbon dioxide
- Formaldehyde impurities in hydrogen fuel gas
- Siloxanes and benzene, toluene, ethylbenzene and xylenes (BTEX) in landfill and biogas
- Water analysis across a wide range of concentrations.
Key Learning Objectives:
- The fundamentals of the SIFT-MS technique, including its operating principles and performance characteristics.
- Understanding how the diverse different chemical ionization mechanisms accessible using SIFT-MS enable trace impurities to be analyzed in diverse bulk gases.
- Insights into how SIFT-MS can be applied to diverse, challenging gas analysis challenges.
The strength of SIFT-MS is that it combines four factors that these other techniques are unable to combine:
- Rapid analysis
- Comprehensive compound detection, including highly reactive species
- Selectivity, and
- Simple, low-cost operation.
