Gas Chromatography The column is heated to prevent analyte condensation within the column reduce band broadening to get sharper peaks all of these control elution of the different analytes prevent analyte condensation within the column reduce band broadening to get sharper peaks all of these control elution of the different analytes 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 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 sequentially splitting the sample into smaller portions to inject at the same time through parallel ports 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 sequentially ANSWER DOWNLOAD EXAMIANS APP

Gas Chromatography Helium is generally preferred as carrier gas over nitrogen and hydrogen because all of above it doubles up as a party gas for balloons and funny voices it has a lower viscosity it is inert all of above it doubles up as a party gas for balloons and funny voices it has a lower viscosity it is inert ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Column bleeding occurs when traces of the stationary phase are eluted the column breaks during installation and causes personal injury the column is cracked and stationary phase leaks out elution of the analyte is extended over time traces of the stationary phase are eluted the column breaks during installation and causes personal injury the column is cracked and stationary phase leaks out elution of the analyte is extended over time ANSWER DOWNLOAD EXAMIANS APP
