Definitions There are two prominent sampling methods used in gas detection: Sample-draw and passive diffusion. A sample-draw system uses a pump to draw sample back into the instrument, where it enters the sensor for analysis, and is then exhausted to the atmosphere or vent line. Gas detection instruments with passive diffusion sensors do…
Very simply, since no two toxic gas detection applications are the same. We admit that this concept has been obscured under the quite false rubric that “All gas detection is confined entry.” Certainly, a goodly percentage of all portable gas detection instruments are designed as if they are intended for the confined entry application. These…
First, let’s define the terms: “Continuous” monitoring means that each sampling point is being monitored all the time, and in most cases, the concentration displayed reflects what is truly happening at the point in real time. There are certain exceptions to this involving instrument techniques that run batch analysis, but that is beyond the scope…
Thanks for your question. The answer depends on what you mean by “double,” and even on how we define “detector.” Usually, “detector” means the sensing element within the instrument. But, people sometimes refer to the entire instrument as the detector. Now, if the sensor for carbon monoxide also responded to propane, this would not be…
Gas detection methods have been changing and evolving and awareness has heightened as well, along with the ever changing methods of sterilization. To answer your question regarding what “most” hospitals are using to monitor EtO, a fair response would be narrowed down to either electrochemical sensors or gas chromatographs (GCs). Interscan has sold close to…
