A gas detector is a device which detects the presence of various gases within an area, usually as part of a system to warn about gases which might be harmful to humans or animals. Gas detectors can be used to detect combustible, toxic, and oxygen and CO2 gases. This device may be used in firefighting.
UV detectors function on the capacity of many compounds to absorb light in the wavelength range 180 to 350 nm. The sensor cell usually consists of a cylindrical cavity about 1 mm I.D and a few mm long, having a capacity that ranges from about two micro-liters to eight micro-liters. By interposing a monochrometer between the light source and the cell; light of a specific wavelength can be selected for detection and, thus, improve the detector selectivity. Alternatively a broad band light source can be used and the light after passing through the cell can be optically dispersed by prism or grating and allowed to fall onto a diode array. By monitoring a specific diode, the detector can be made specific for those substances that absorb at that particular wavelength. If the output from all the diodes is scanned then a UV absorption spectrum can be obtained to aid in solute identification. The fixed wavelength UV detector has a sensitivity of about 1 x 10-8 g per ml at a signal to noise ratio of two.
