What is Determination of Mono‐, di‐ and Tri‐substituted Butyltin, Phenyltin and Methyltin Compounds as Free Halides Using Gas Chromatography with Flame Photometric Detection about?
## Abstract A simple chromatographic procedure has been developed for the sensitive determination of mono‐, di‐ and tri‐substituted butyltin, phenyltin, and methyltin compounds as halides. The organotin compounds were separated on a DB‐1 capillary column and detected by flame photometric detection (FPD) equipped with a 611.5 nm filter. Pretreatment of the capillary column with an ethyl acetate solution of hydrobromic acid, or doping of standard solutions with hydrobromic acid, was found to be necessary if reproducibly sharp peaks of organotin halides were to be obtained. Column treatment and acid doping did not cause any background problems or undesirable degradation of the organotin compounds. Three different standard solutions in ethyl acetate had to be Jrepared, because undesirable degradation of the organotin halides was observed when all the compounds were dissolved in the same solution. The first, standard solution I, contained tri‐__n__‐butyltin chloride (TBTCI) and trimethyltin chloride (TMTCI), the second, standard solution II, contained triphenyltin chloride (TPTCI), and the third, standard solution III, contained hydrogen bromide and the other organotin compounds: di‐__n
