What is retention time of hexane in gas chromatography by using Flame ionization detector?
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.
Compare between GC ms detector and fid?
The detector is very sensitive towards organic molecules (10-12 g/s, linear range: 106 -107), but relative insensitive to a few small molecules e.g. N2, NOx, H2S, CO, CO2, H2O. If proper amounts of hydrogen/air are mixed, the combustion does not afford any ions. If other components are introduced that contain carbon atoms cations are produced in the effluent stream. The more carbon atoms are in the molecule, the more fragments are formed and the more sensitive the detector is for this compound (-- > response factor). However, due to the fact that the sample is burnt (pyrolysis), this technique is not suitable for preparative GC. In addition, several gases are usually required to operate a FID: hydrogen, oxygen (compressed air), and carrier gas.Many GC instruments are coupled with a mass spectrometer, which is a very good combination. The GC separates the compounds from each other, while the mass spectrometer helps to identify them based on their fragmentation pattern.
How do you test uv flame detector?
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.
What is the normal color of the gas flame in a halide leak detector?
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.
What device may eliminate the inaccuracy of using only flame color to identify an element?
This is a spectrometer.

How does flame detector works?
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.

What does the acronym 'fide' stand for?
The acronym FIDE stands for many things. Some things the acronyms FIDE stands for are Foundation for Investment and Development of Exports, Flame-Ionization Detector Electrometer, Formally Integrated Data Environment and many more.
Is flame detector an analog or digital signal?
digital signal
Explain why you would or would not expect significant ionization in the flame?
Ions may not form in a flame because the high temperature typically leads to the dissociation of molecules into atoms. At such high temperatures, most atoms are in the gaseous state, where they are unlikely to form ions. However, in some cases, particularly with metals, ionization can occur due to the presence of high-energy photons or collisions with other particles leading to the formation of ions.

What instrument can be used to determine the identity of an element if its flame color is the same of another element?
