Insulation gas leakage detector

This method is well known and widely used for goals of detection of various chemicals when efficiency matters. For example, SF6 LaserGasTest can detect the presence of about 10 ppb of sulfur hexafluoride, which is equivalent to the detection of a sulfur hexafluoride molecules of the 100 000 000 (one hundred million) of air molecules.

MPS IAQ Sensor - Indoor Air Quality Monitor | NevadaNano

Typical indoor air contains dozens of chemicals at concentrations in the parts-per-billion (ppb) or parts-per-million (ppm) range. This is well below their odor thresholds. But just because we can’t smell these chemicals doesn’t mean they don’t harm us. The World Health Organization’s 30-minute exposure limit for the carcinogen formaldehyde is 80 ppb. That is twelve times lower than the concentration at which …
