HCl, HBr, and HF Sorbent Traps
Easy and effective measurements of hydrogen halides
Hydrogen chloride (HCl), hydrogen bromide (HBr), and hydrogen fluoride (HF) sorbent traps are used for measuring hydrogen halides in any sampling environment for engineering studies and control technology optimization, as well as stack measurement check-ups between quarterly testing.
HCl sorbent traps promise to provide a quick, easy, and effective alternative to FTIR and Method 26/26A. With reasonable sample volumes, it's possible to quantify flue gas HCl concentrations lower than 0.1 PPMV.
By using ion chromatography, each trap section is dissolved into just 10 mL of solution, thanks to a specially developed chloride extraction procedure. Low dilution means high chloride concentration, which in turn means lower sample volume requirements. We use a well-tested vapor phase spiking procedure, sampling spiked/unspiked pairs, to ensure method accuracy.
Agreement with existing methods including M26/26A and M321
Low chloride background on the sorbent makes it easy to measure low levels
Aerosol pre-filter is available to prevent interference by chloride salts
