Gas Chromatography The column is heated to all of these prevent analyte condensation within the column reduce band broadening to get sharper peaks control elution of the different analytes all of these prevent analyte condensation within the column reduce band broadening to get sharper peaks control elution of the different analytes ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Split injection is carried out by splitting off some of the sample so that it does not enter the column None of these splitting the sample into smaller portions to inject at the same time through parallel ports splitting the sample into smaller portions to inject sequentially splitting off some of the sample so that it does not enter the column None of these splitting the sample into smaller portions to inject at the same time through parallel ports splitting the sample into smaller portions to inject sequentially ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Column bleeding occurs when the column breaks during installation and causes personal injury traces of the stationary phase are eluted the column is cracked and stationary phase leaks out elution of the analyte is extended over time the column breaks during installation and causes personal injury traces of the stationary phase are eluted the column is cracked and stationary phase leaks out elution of the analyte is extended over time ANSWER DOWNLOAD EXAMIANS APP
