Abstract

This Uganda Standard covers test method for online determination of vapor phase moisture concentration in natural gas using a tunable diode laser absorption spectroscopy (TDLAS) analyzer also known as a TDL analyzer. The particular wavelength for moisture measurement varies by manufacturer; typically between 1000 and 10?000?nm with an individual laser having a tunable range of less than 10?nm. (This standard is based on ASTM D7904-21, Standard Test Method for Determination of Water Vapor (Moisture Concentration) in Natural Gas by Tunable Diode Laser Spectroscopy (TDLAS))..
