To test a UV flame detector, you can use a UV flashlight to simulate the presence of a flame by shining the light near the detector. The detector should respond by triggering an alarm or other designated response. It is important to follow the manufacturer's guidelines for testing procedures and frequency.
The normal color of the gas flame in a halide leak detector is blue. If the flame changes to a different color, it can indicate the presence of halides in the gas being tested.

A flame detector is a fire protection device, which detects the flame in the place where it is fixed and issues an alarm thereby alerting nearby people to the danger of fire. In most of the manufacturing companies, furnace flame detector is used in order to detect and prevent fire. Flame detector responds either to radiant energy visible to the human eye or outside the range of human vision. Most flame detectors work either by optical flame detector or flame ionization detector but some of them use combination of both detectors.Flame detector works at specific ranges, which uses optical sensors to record the incoming radiation at a particular wavelength. The energy radiated from the flame is electromagnetic radiation and it can be identified at various spectral ranges like UV, IR and VIS. Depending upon the sensor used there are number of flame detectors available they are infra red flame detectors, ultra violet flame detector, UV/IR, IR/IR and tripe IR spectral band detector. Flame detector has a cone of vision that defines the effective capability of sensing fire. It is inefficient for slow fires however it responds faster for rapidly developing fire like combustible gas and liquid. It is available in different shape and size.

The type of flame is just a normal flame
The retention time of hexane in gas chromatography using a Flame Ionization Detector (FID) can vary depending on the specific chromatographic conditions such as column type, temperature, and flow rate. However, typically, the retention time for hexane using an FID ranges between 2-4 minutes on a non-polar column.
The ionization type smoke detector was invented in 1931 in Switzerland.
