How to Measure Sub-ppm Levels in a Complex Gas Matrix
Recorded Wednesday, November 5, 2025, at Lesman Instrument Company
When you need to measure sub-ppm levels of known and unknown gases, identify unknown odors and gases, and quantify known compounds, Gasmet's FTIR analyzer can help improve your gas detection processes, increase your trust in these systems, and ensure worker safety.
In this webinar, you'll discover how Gasmet’s advanced cell design and signal processing deliver multi-component, sub-ppm analytical power, even in the most demanding environments.
This session covers how to:
- Rapidly identify and quantify gases and vapors in real field conditions
- Measure gases at sub-ppm levels including TIC's, WAGs, VOC's such as BTEX, ACN, EtO, Formaldehyde, inorganics such as acid gases (HCN, HCl, HF), NO, NO2, Ammonia, Silanes, SO2, CS2
- Identify the source of employee reported smells and odors using the NIST/EPA 5000+ reference library
- Achieve high accuracy and sensitivity without calibration gases
- Ensure robust, reliable, and regulatory-compliant performance
- Stay future-ready with expandable gas libraries
