Quantitation of Hydrogen and Methane Dissolvedin Hexanes, Toluene and Water

Introduction

The amount of gases dissolved in a liquid solution may alter the functionality of the solution and affect the stability and reactivity of other dissolved components. A high sensitivity detector is required for analysis of these gases as the amounts dissolved in a solution are generally at trace levels. Since inorganic gases are not detectable by the flame ionization detector (FID), the choice of the detectors is between the barrier discharge ionization detector (BID) and the thermal conductivity detector (TCD). As BID possesses higher sensitivity compared to TCD and measures virtually all compounds with the exception of helium and neon, BID is the preferred detector for high sensitivity analyses of inorganic gases. This article introduces analysis of hydrogen and methane in hexanes, toluene and water using the Shimadzu BID-2030.
