More liquid chromatography solutions from Varian 1. An analytical system that will solve almost any LC p r o b l e m . . . Model 8520 LC with the new Varichrom UV-Vis detector. This is the most capable liquid chromatography system available today. The 8520 Liquid Chromatograph is designed for both analytical and preparative work. The new Varichrom is a nearly universal detector covering the entire UV-Vis range from below 200 nm to 700 nm. This extended wavelength range lets you optimize for most organics and permits monitoring many new compound classes such as lipids, mono-olefins and carbohydrates. The chromatograph's superior syringe pump provides precisely controlled pulseless flow and low noise so you can detect and measure the smallest quantities. Varichrom and the 8520 couple directly in a configuration that eliminates dead volume and preserves peak resolution. For full details on this capable combination, shown below, circle Reader Service No. 243.
2. A new Automatic LC that will increase sample "^^ throughput, improve reproducibility, and calculate and report analysis results. Varian's new Automatic LC System handles up to 60 samples unattended. It is completely automatic from injection through separation, calculations and final report. The system's Model 8500 positive displacement pump with Autorefill provides the pulseless, repeatable flow required for good accuracy, reproducibility, detectability and high efficiency. The reliable 8050 AutoSampler obtains reproducibility with a coefficient of variation less than 1 %. The third system component, the CDS-111 Chromatography Data System, gives you full computer power to calculate the results from a single sample by any or all six methods including internal standard, external standard, normalization and response factors. Nine completely different method files can be stored for use as dictated by the AutoSampler. The CDS-111 permits closed loop operation of all three system components.
