Gas Chromatography The GC trace obtained after an experiment is called a chromatograph graph chromatogram chromatophore chromatograph graph chromatogram chromatophore ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography The column is heated to prevent analyte condensation within the column all of these reduce band broadening to get sharper peaks control elution of the different analytes prevent analyte condensation within the column all of these 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 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 splitting off some of the sample so that it does not enter the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Sample injection is considered successful if the sample is spread evenly along the column the sample is concentrated at the start of the column the sample is homogenously spread along the column all of the sample in the injector has been added to the column the sample is spread evenly along the column the sample is concentrated at the start of the column the sample is homogenously spread along the column all of the sample in the injector has been added to the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography A retention gap is placed between the injector and the front of the column to retain the sample and release it gradually to the column retain contaminants and prevent them from reaching the column prevent backflush of the injected solution All of these retain the sample and release it gradually to the column retain contaminants and prevent them from reaching the column prevent backflush of the injected solution All of these ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography What does the retention factor, k', describe? All of these The distribution of an analyte between the stationary and the mobile phase The velocity of the mobile phase The migration rate of an analyte through a column All of these The distribution of an analyte between the stationary and the mobile phase The velocity of the mobile phase The migration rate of an analyte through a column ANSWER DOWNLOAD EXAMIANS APP
