1. Differences and performance between chemical analyzers and sensors

In the field of gas detection, a distinction must be made between analyzers (analytical instruments) and chemical sensors.

• Analyzers

  These are generally relatively complex systems, combining mechanical, chemical and electrical components. They are often costly, cumbersome and energy-intensive, making them unsuitable for on-site measurements and large-scale deployment. What's more, these instruments are often plagued by long response times, either due to the detection technique itself, or to the need for sample handling.

  This category includes chromatographs and various spectrometers. The main advantages of these instruments are their ability to provide a complete and precise analysis of the gas sample. These instruments can be found in specialized laboratories for the analysis of...
