TL;DR: A wide variety of mono-, di-, and tri-substituted tin compounds are transformed to, and transmitted as, chlorides, bromides, or iodides on injection into a gas chromatographic system doped with HCl as discussed by the authors.

TL;DR: In this paper, it was suggested that the chemiluminescent emission of a few of the prominent atomic iron lines in the ultraviolet (the less sensitive response from the stoichiometric hydrogen-air flame is spectrally more complex).

TL;DR: Ruthenocene can be determined with surprisingly high sensitivity and selectivity by gas chromatography in flame photometry as mentioned in this paper, and it is shown that ruthenium is the strongest luminescing and best performing species in the flame photometric detector.
Abstract: Ruthenocene — bis(cyclopentadienyl)ruthenium — can be determined with surprisingly high sensitivity and selectivity by gas chromatography – flame photometry. The detector's response relies mainly on an unidentified emission system (RuH?) with major peaks at 484 and 528 nm, while some familiar atomic lines show up as well. Without interference filter, the minimum detectable amount of ruthenocene, at S/N = 2, is approximately 2 pg (or 2 × 10−13 g/s or 1 × 10−15 mol/s), the elemental selectivity ruthenium/carbon 4 × 105, and the linear range 1:4 × 104. These calibration characteristics place ruthenium among the strongest luminescing and best performing species in the flame photometric detector. In fact, under conditions optimized for ruthenocene, ruthenium responds stronger than other FPD-active atoms (Sn, P, Cr, S, B). Fortunately, quenching effects are very weak: for instance, it takes about 1600 ppm (v/v) of methane in the detector to reduce the ruthenocene peak height by 50%.Keywords: ruthenocene, gas ch...
