A gas chromatogram of a mixture of toluene and ethyl (a) Measure w1/2 for each peak to the nearest 0.1 mm. When the thickness of the pen trace is significant relative to the length being measured, it is important to take the pen width into account. It is best to measure from the edge of one trace to the corresponding edge of the other trace, as shown at the bottom of the left column. (b) Find the number of theoretical plates and the plate height for each peak.
