Flame ionization detectors are used most often for organic compounds.

The first flame ionization detector was developed in 1957 in Australia.

Cost: Flame ionization detectors are relatively inexpensive to acquire and operate.

Hence the current use of flame ionization detectors.

Flame ionization detectors cannot differentiate between different organic substances.

Flame ionization detectors are used very widely in gas chromatography because of a number of advantages.

The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same.

In a flame ionization detectors, the separated sample from the column is directed into a flame.

Flame ionization detector.

The temperatures of the injector and the flame ionization detector were 220 C and 250 C, respectively.

It maintains a laboratory equipped with sophisticated instruments like gas chromatographs, infrared emission pyrometers and flame ionization detectors.

A flame ionization detector (FID) is a scientific instrument that measures the concentration of organic species in a gas stream.

Flame ionization detectors can be used to measure methane levels as well as total VOC levels.

Instantaneous monitoring consists of walking over the surface of the landfill, while carrying a flame ionization detector (FID).

Flame Ionization Detectors (shortened FID) is a common type detector used in gas chromatography.

The most common type of detector, the flame ionization detector, is sensitive to compounds containing C-H bonds, but not very sensitive to things like water.

The retention time of the probe molecule is then measured by traditional GC detectors (i.e. flame ionization detector or thermal conductivity detector).

The most commonly used detectors are the flame ionization detector (FID) and the thermal conductivity detector (TCD).

The separated gases are detected by thermal conductivity detector for atmospheric gases, by flame ionization detector for hydrocarbons and oxides of carbon.

The GC is coupled with either a mass spectrometer detector (MSD) or a flame ionization detector (FID).

Detection of gas concentrations usually involves the use of a flame ionization detector (FID) and a thermal conductivity detector (TCD).

Since the TCD is less sensitive than the flame ionization detector and has a larger dead volume it will not provide as good resolution as the FID.

The molecules are typically extracted in a solvent, then separated in a gas chromatograph, and finally determined with a suitable detector, such as a flame ionization detector or a mass spectrometer.

The PDD in helium photoionization mode is an excellent replacement for flame ionization detectors in petrochemical or refinery environments, where the flame and use of hydrogen can be problematic.

Method 8015D may be used to determine the concentrations of various nonhalogenated volatile organic compounds and semivolatile organic compounds, including fuel oxygenate compounds, by gas chromatography using a flame ionization detector (FID).

This signal is called the free induction decay (FID).

This free induction decay occurs on a timescale of 1-100 microseconds depending on instrument settings.

The raw free induction decay data obtained when performing the experiment are stored according to the formatting preferences of the instrument manufacturer.

The shape of lines in a nuclear magnetic resonance (NMR) spectrum is determined by the process of free induction decay.

Free induction decay (FID)

The resulting signal is called a free induction decay (fid), transient or interferogram that consists of a superposition of sine waves.

"The Quantum Origins of the Free Induction Decay Signal and Spin Noise,"

This microwave signal generated by the rotating magnetization vector is called free induction decay (FID) (see page 175 of ref ).

The form in which the data is stored varies, ranging from line lists that can be graphically displayed to raw free induction decay (FID) data.

Over time, this distribution can lead to a dispersion of the tight distribution of magnetic spin vectors, and loss of signal (Free Induction Decay).

This signal is known as the free induction decay (FID), and it contains the vector sum of the NMR responses from all the excited spins.

In Fourier transform ion cyclotron resonance and Orbitrap type mass spectrometers the signal intensity (Y-axis) is related to the amplitude of the free induction decay signal.

The closest parallel to SR is "pulsed NMR", in which one observes time-dependent transverse nuclear polarization or the so-called "free induction decay" of the nuclear polarization.

In Fourier Transform NMR, free induction decay (FID) is the observable NMR signal generated by non-equilibrium nuclear spin magnetisation precessing about the magnetic field (conventionally along z).

The resulting composite signal, is called a free induction decay, because typically the signal will decay due to inhomogeneities in sample frequency, or simply unrecoverable loss of signal due to entropic loss of the property being measured.

The following equation relates the Ernst angle, theta, to the experimental interpulse delay, d1; the duration of the Free induction decay, aka "acquisition time", or "at"; and the longitudinal relaxation time of the spin in question, T:

In Fourier Transform NMR spectroscopy and imaging, a pulse sequence describes a series of radio frequency pulses applied to the sample, such that the free induction decay is related to the characteristic frequencies of the wanted signals.

In practice, the value of which is the actually observed decay time of the observed NMR signal, or free induction decay, (to 1/e of the initial amplitude immediately after the resonant RF pulse)-- also depends on the static magnetic field inhomogeneity, which is quite significant.
