1. A high throughput gas chromatographic (GC) system for analysis of an additive in a polymer, comprising:
an inlet through which a sample of the polymer is injected;
a column to which the sample injected from the inlet is introduced;
a splitter for distributing the sample introduced into the column, to a flame ionization detector (FID) and a mass spectrometer (MS);
a first restrictor which is a path through which the sample moves between the splitter and the flame ionization detector;
a second restrictor which is a path through which the sample moves between the splitter and the mass spectrometer;
wherein a ratio of a length of the first restrictor to a length of the second restrictor is 59.6:40.4 to 76.8:23.2,
wherein the mass spectrometer is for qualitative analysis of the sample;
wherein the flame ionization detector is for quantitative analysis of the sample, and
wherein the high throughput gas chromatographic system is configured to simultaneously perform qualitative analysis and quantitative analysis of the sample.
