2. Mass Spectrometry (MS)

Mass spectrometry is a potent analytical tool for ionizing and separating gas molecules depending on their mass-to-charge ratios. For thorough gas analysis, it frequently works in tandem with gas chromatography. Higher resolution, enhanced sensitivity, and the ability to accurately analyze complicated gas mixtures are all results of improvements in MS techniques and equipment.

3. Fourier Transform Infrared (FTIR) Spectroscopy

FTIR spectroscopy is a non-destructive method for identifying and measuring gas molecules based on how well gas molecules absorb infrared light. This method is beneficial for locating and measuring dangerous air contaminants and trace gases. The development of portable, field-deployable devices and advances in spectral resolution and sensitivity are recent developments in FTIR methods and tools.
