The peaks in the chromatogram are too large. Two new experiments could be performed on the same sample to attempt to reduce the peak size. First, reduce the injection volume. If reducing the volume does not cause the peak height to remain on the paper, then a second experiment can be performed where the full scale deflection (the input voltage) is increased. Remember, the higher the input voltage, the smaller the peak.
Identify two different things that could be done in another experiment to produce a better chromatogram than the one shown below.
