Technical Abstract: The TRS-Medor gas chromatograph (GC) is an instrument used to measure reduced sulfur compounds. The TRS-Medor GC is equipped with an internal calibration system designed to use permeation tubes as internal reference standards. Custom ordering of permeation tubes is costly and permeation tubes expire quickly, needing to be replaced roughly every six to twelve months. As an inexpensive alternative, a method was developed to create custom-made permeation tubes in the laboratory. In a recent field study, the TRS-Medor was deployed at a poultry farm in Hadley, Kentucky to measure gaseous sulfur emissions from animal waste in the house. The instrument was calibrated using a custom-made dimethyl sulfide (DMS) permeation tube. The construction and calibration method for a DMS permeation tube along with the results of the field study are presented.
