Colorimetric tubes

Simplicity Compared to most of the instrumentation currently in use, colorimetric tubes have no moving parts. 

Sturdiness Colorimetric tubes hold up under tough conditions. 

Reliability Colorimetric tubes are unaffected by power surges or outages. Tubes do not rely on electrical power. If the power goes out or surges, it does not have an effect on the operation. 

Pull a vacuum (15 in Hg) on the solvent storage tank, and charge with solvent by sucking it from the appropriate drum. Check the tank level using the level glass. Periodically check the air for toluene by using colorimetric tubes. 

Periodically check operating area for leaks with colorimetric tubes. 

Allow excess to evaporate. Check area with explosimeter and colorimetric tubes. Do not enter explosive atmosphere. 

Sniff area with colorimetric tubes for hazardous solvents. 

Acoustic wave sensors are also used to detect nerve and blister agents. The surface acoustic wave chemical agent detector (SAW Mini-CAD) is a commercially available, pocket-sized instrument that can monitor for trace levels of toxic vapors of sulfur-based mustard agents (e.g., distilled mustard) and G nerve agents (e.g., tabun, sarin, soman) with a high degree of specificity. Colorimetric tubes are the...

Lewisite (L). Colorimetric tubes are available which can detect organic arsenic compounds as well as arsine. Detection with PIDs or FIDs may be possible. Detection and identification with FT-IR is possible provided that the appropriate reference spectra are available. 

Liquids Some, but not all components of Sulfur/Arsenical Vesicants can be detected by M8 paper. All components of Sulfur/Arsenical Vesicants can be detected by M9 papers. The APD 2000 provides semi-quantitative identification of sulfur mustard/Lewisite mixtures. Colorimetric tubes are available which can detect thioethers, organic arsenic compounds as well as arsine (AsHg). Detection with PIDs or PIDs may be possible. Detection and identification with FT-IR is possible provided that the appropriate reference spectra are available.
