ABSTRACT:
A device and method for measuring the level of elemental sulfur present in a gas in a gas line. The method may include the steps of: collecting a sample of elemental sulfur-containing gas from the gas line, wherein the sample is collected on an outer surface of a probe by condensing some or all of the elemental sulfur-containing gas in the gas line on a surface of the probe while the gas line is operational, the probe having a piping partially disposed within for providing a cooling medium to the probe and being adapted for insertion into the gas flow stream of the gas line, separating the elemental sulfur from other species in the sample into an amount of elemental sulfur; and analyzing the amount of elemental sulfur collected.
