Calibration of the Tube	Diffusion Tube Method
Interference & Coexistence	Mercaptans and Butane will produce similar stain and will give higher readings. Under the condition of asbolute humidity at more than 3mg/L, hydrogen sulphide (H₂S) does not affect the reading otherwise the H₂S will produce a similar stain and gives higher reading. Propane does not affect the reading if the concentration is less than 0.8%.
