Gas Chromatography A retention gap is placed between the injector and the front of the column to retain contaminants and prevent them from reaching the column All of these prevent backflush of the injected solution retain the sample and release it gradually to the column retain contaminants and prevent them from reaching the column All of these prevent backflush of the injected solution retain the sample and release it gradually to the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Split injection is carried out by 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 splitting off some of the sample so that it does not enter the column ANSWER DOWNLOAD EXAMIANS APP
