Basic lab tasks prove this LC team performs best.
You can judge an LC system by its quantitative, qualitative and preparative capabilities. That's why everything else in the field gives way to this quartet of Perkin-Elmer LC instruments.
I .The SERIES 3B solvent delivery system: the most powerful around. Its dual pumps can run independently on separate analyses, or together on one analysis, for faster throughput or solvent programing. Its flow rate range of 0.1-60 ml/min., the widest anywhere, allows this one pumping system to be used for both analytical and preparative work.
2. The Model LC-75 spec-trophotometric detector: its linearity over a wide dynamic
range makes quantitative analysis reliable. Precise wavelength resettability in the far UV and visible ranges eliminates frequent recall bration.
3. The Model LC-75 Autocon-trol: used with the LC-75, it gives you the most advanced peak analysis system available today. You get qualitative data on submicrogram samples like never before.
4. The SIGMA 10B Chromatography Data Station : the computer that automates the system. You can set up different conditions for different samples, successive injections at different solvent concentrations, and different analytical wavelengths for different methods. Here's an example:
Precise quantitation. This UV-VIS detection system stores baseline corrections in memory during blank gradient runs and subtracts them from subsequent sample analyses. It flattens the baseline across the full range of detector sensitivity, improving quantitative analyses of complex mixtures. This chromatogram displays how the wide dynamic range of the system allows proper detection of both the strongest and weakest absorbing compounds in a single run.
