GAS CHROMATOGRAPHY QUIZ

Reduced risk of column overloading

Increased sample capacity

All of these

Increased resolution

prevent analyte condensation within the column

reduce band broadening to get sharper peaks

control elution of the different analytes

all of these

retention factor

all of these

retention index

retention time

it is inert

it has a lower viscosity

all of above

it doubles up as a party gas for balloons and funny voices

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 sample is spread evenly along 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 concentrated at the start of the column

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

Electron-capture detector
