Gas Chromatography Helium is generally preferred as carrier gas over nitrogen and hydrogen because it has a lower viscosity it doubles up as a party gas for balloons and funny voices all of above it is inert it has a lower viscosity it doubles up as a party gas for balloons and funny voices all of above it is inert ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Theoretical plates are used to estimate the efficiency of a column determine the thickness of the stationary phase None of these measure the distribution of the analyte between mobile and stationary phases estimate the efficiency of a column determine the thickness of the stationary phase None of these measure the distribution of the analyte between mobile and stationary phases ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Sample injection is considered successful if the sample is concentrated at the start of 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 homogenously spread along the column the sample is concentrated at the start of 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 homogenously spread along the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Which of these effects result from slow injection of a large sample volume?

Gas Chromatography The column is heated to prevent analyte condensation within the column all of these control elution of the different analytes reduce band broadening to get sharper peaks prevent analyte condensation within the column all of these control elution of the different analytes reduce band broadening to get sharper peaks ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Column bleeding occurs when 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 the column breaks during installation and causes personal injury traces of the stationary phase are eluted ANSWER DOWNLOAD EXAMIANS APP
