brief introduction

The QTH sulfide content analyzer is an instrument used to measure soluble sulfides and energy in drilling fluids.

scope of application

Widely used in drilling sites of various oil fields, as well as teaching and laboratory applications in various universities such as oil fields, geology, and mineral resources.

Instrument characteristics

Soluble sulfides include hydrogen sulfide (H2S), sulfur ions (s-2), and hydrogen sulfide ions (hs -). The measurement process involves acidifying the mud filtrate in the Garrett gas separator to convert all sulfides into H2S, which is carried out by the carrier gas passing through the sample and foaming. Garrett gas separators separate gases from liquids. The airflow passes through a Dr ä ger tube that reacts with hydrogen sulfide (H2S) and darkens along its length. The length of blackening is proportional to the total amount of sulfides in the mud filtrate. The Dr ä ger tube used in the low concentration range changes from white to brownish black; The Dr ä ger tube used in the high concentration range changes from light blue to smoky black. Usually, pollutants in the mud do not cause this color change.
