Gas Chromatography Split injection is carried out by splitting the sample into smaller portions to inject sequentially splitting the sample into smaller portions to inject at the same time through parallel ports None of these splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject sequentially splitting the sample into smaller portions to inject at the same time through parallel ports None of these splitting off some of the sample so that it does not enter the column ANSWER DOWNLOAD EXAMIANS APP
