Effect of carrier gas flow geometry on the response of sulfur flame photometric detectors for gas chromatography

Chlorine-selective detector for microcolumn liquid chromatography

“…An attempt was made to decrease the signal reduction by organics through oxidation before entering the flame, in a way similar to that described by Fredriksson and Cedergren (24) for sulfur-flame photometric GC detectors. Oxygen was supplied through a modified inner reactor tube, ending 3 cm from the outlet of the outer reactor tube.…”

Evaluation of Non-Linear FPD Response

“…Equation 23 expresses the dependency of FPD sulphur sensitivity on experimental parameters, such as used compound (fraction x in cpJ, purity of operational gases and background level during detection (cpz and q3), column packing ((p3), etc. As it can be seen, the specification of the sensitivity of FPD is meaningless, if the experimental conditions and thus values of parameters cpl to cp3 are not specified.…”

A capillary column gas chromatography, resonance enhanced multiphoton ionization, time-of-flight mass spectrometry, laser-induced fluorescence, flame ionization detection system for the determination of polynuclear aromatic compounds in complex mixtures

“…Such detectors, which show promise for specialized applications, are the inductively coupled plasma (ICP) (55), the microwave induced plasma (MIP) (56), and the atmospheric pressure active nitrogen (APAN) detector (57). However, the most popular system is the flame photometric detector (FPD) (58,59).…”
