DMDS Detection

Hi,

I am looking into a Gas Detector that is capable of detecting DMDS (Dimethyl Disulfide) with an alarm limit of .5PPM. Any suggestions?

FYI, the application is for a Sulfur Injection skid. I have contacted several gas detection vendors and the only recommendation I seem to get is an H2S detector.

Thanks in Advance!

    Solid state gas detectors can be used to detect dimethyl disulfide in the parts per million. To my knowledge, they don’t have the sensitivity to support alarm setting at 0.5 ppm. A typical range for a solid state sensor configured for dimethyl sulfide is 0 – 10 ppm. Irvine, CA-based International Sensor Technology offers a solid state gas detector for dimethyl disulfide. You may call or write IST to learn more about the limits of applicability of its product.

    Besides solid state sensors, another technology available to detect dimethyl disulfide is gas detector tubes. Nonetheless, these tubes are portable, single use devices, unsuitable for continuous gas monitoring. Dräger (Lübeck, Germany) makes a model for DMDS detection.
