Gas Chromatography Split injection is carried out by 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 splitting the sample into smaller portions to inject sequentially 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 at the same time through parallel ports splitting the sample into smaller portions to inject sequentially None of these ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography In column switching chromatography compounds trapped on one column are eluted to another column any of the above the flow to the column is switched on and off repeatedly one column is removed and replaced by another compounds trapped on one column are eluted to another column any of the above the flow to the column is switched on and off repeatedly one column is removed and replaced by another ANSWER DOWNLOAD EXAMIANS APP

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
