Excellent Analytical Precision

The excellent precision of Adept Gradient System 4S, which uses the WaveQuest CE4300 Ultra fast scanning detector is demonstrated by seven repeat injections and elutions of a soft drink.

The results are shown here in overlay, each chromatogram being offset by 50mAbs. The phosphate buffer : methanol baseline was recorded first, and is shown on this plot.

The result for the component Caffeine is shown in a summary report comment. This shows excellent reproducibility of 0.33% RSD.

Simultaneous 4 Wavelength Monitoring

The traces shown here were obtained by monitoring four different wavelengths simultaneously for a ten minute period of an elution.

The experiment was carried out using a Cecil Adept System 4 with a WaveQuest, CE4300, UV-Visible detector in its variable wavelength detector mode.

The very fast operating speed of the detector results in excellent quality peaks, captured in real time by DataStream, shown here in overlay.
