Abstract : An evaluation is made of the experimental conditions that must be considered in quantitative impurity determinations in the 0.01 to 0.000001 range with a gas chromatograph. In this evaluation particular attention is given to flame parameters (gas velocities and electrode voltages) and detector linearity. The dependence of detector response on molecular structure and, in particular, on various functional groups is investigated for a variety of compounds. It is shown that even moderate thermal cracking between the column and the flame has a profound effect on the detector response. A practical prescription for impurity determination with flame-ionization detectors is given. (Author)
