Which of the following statements about a gas chromatogram is correct? O The height of the peak in the gas chromatogram is proportional to the amount of the compound present in the sample. O Tailing indicates that the gas chromatograph has been overloaded. O If the peaks are broad this could indicate that the sample is too polar. If the peaks overlap, the temperature can be increased at a slower rate to improve resolution. The retention time can be used to identify a compound by comparison with literature values, regardless of the conditions used.
