Using Two Scans with One Detector

The more modem approach is to use just one detector to extend the dynamic range. This has typically been done by using the detector both in pulse and analog mode, so 

The more modern approach is to use just one detector to extend the dynamic range. This has typically been done by using the detector both in pulse and analog mode, so high and low concentrations can be determined in the same sample. There are basically three approaches to using this type of detection system two of them involve carrying out two scans of the sample, whereas the third only requires one scan.
