H2S represents no considerable reactivity.Ī list of Reactive and Non-Reactive Gases to help when choosing Calibration or Bump test gas cylinders and accessories. Unlike non-reactive gases, reactive gases require higher flow (they will use a 1.0 LPM regulator, instead of a 0.5 LPM) and need corrosion-resistant equipment as corrosive and sticky (stainless steel regulators and Teflon tubing).
The principal danger is that failure to use compatible materials and proper calibration procedures can result in dangerously inaccurate (low) readings and increased response times. Because of their greater tendency to be depleted from a gas sample by the exposed surfaces of gas detection systems, special care must be taken to ensure accurate monitoring results.
The elements in row 7 are the most reactive, but technically. For example, Te, or Tellurium, is in group 16 and row 5.
Reactive gases are defined as gases which, because of their high chemical activity, are easily sorbed (adsorbed) by the exposed surfaces of gas detection systems including detector housings, calibration adapters, and remote sample draw accessories (tubing). The more reactive elements on the Periodic Table are farther down in the rows.
