Gas Chromatography Sample injection is considered successful if the sample is spread evenly along the column all of the sample in the injector has been added to the column the sample is concentrated at the start of the column the sample is homogenously spread along the column the sample is spread evenly along the column all of the sample in the injector has been added to the column the sample is concentrated at the start of the column the sample is homogenously spread along the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Split injection is carried out by splitting the sample into smaller portions to inject sequentially splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject at the same time through parallel ports None of these splitting the sample into smaller portions to inject sequentially splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject at the same time through parallel ports None of these ANSWER DOWNLOAD EXAMIANS APP
