Colorimetric odorant level test in natural, synthetic and L.P. gas and the like

摘要

Measuring of mercaptan-based odorants present in natural, synthetic, L. P. gases and the like. Conventionally, an operator smells the gas or uses apparatus which gives uncertain results. Alternatively, expensive laboratory equipment can be used, but this is not available to a field operator. The present test includes simple apparatus which can be connected to a gasline and which includes a disposable reagent tube having a plurality of liquid chemical reagents therein separated by membranes. The gas flow is bled through the first solution and then the solutions are mixed so that a color develops which can be compared with a standard color slide or the like thus indicating the quantity of the odorant in parts per million present in the gas.
