The universal autosampler for HPLC The Smartline Autosampler 3950 is a high throughput autosampler of robust design, developed to meet the challenges of the modern analytical laboratory. The Smartline Autosampler 3950 offers: • flexible use of microtiter well plates or trays for standard vials • 2 x 384 positions maximum sample capacity • injection cycle time < 60 s, including needle wash • full or partial loopfill injection, as well as μl-pickup • easy internal standard addition, sample dilution or derivatization • priority sample feature • convenient access for loading and maintenance • optional sample tray cooling and biocompatible liquid handling Confident injection – For all injection modes, sample injection with pressure-assisted sample aspiration (PASA™) is selectable. The sample needle will not be moved to an extra port for injection. This tech­ ique not only provides for excellent accuracy and precision, but reduces the risk n of bubbles and avoids contamination. Thorough cleaning – Highly efficient washing of tubing and needle (inside and outside) avoids sample carryover. Easy control – Complete integration into KNAUER’s ChromGate® (based on the EZChrom Elite™ kernel) and ClarityChrom® chromatography data software make the autosampler easy to control, including context-sensitive online help.
