Summary

Description

Figure 6. This chromatogram shows the separation of sugars in a mixture. In an analog chromatogram, the line would be smooth since it would come from a continuous signal that was being recorded in real-time. Images like this will often show stair-stepping on the peaks, a result of a computer sampling the signal periodically (possibly 20 to 50 times/sec depending on settings), and the resulting image is a connect-the-dots display of the sampled readings. This is a characteristic difference between real-time strip-chart analog recording and digital systems (though not a criticism of this particular chromatogram).
