EL2000H Headspace Autosampler Easy To Use Just load the samples and run the analysis with no extra downtime. The full-color touch screen interface provides easier system accessibility and usability. The touch screen eliminates drilldown, simplifying instrument control for both novices and experienced users. All system parameters and settings are graphically displayed for a quick and easy set-up requiring minimal user training. For routine analyses, the headspace sampler features a one-touch operation. After loading the sample, you just need to enter a range of vial numbers and push the START button. The display shows real-time status and allows for easy stand-alone operations. Operations The robotic vial processing operation allows for sample analysis in a straightforward and systematic way. The sample vials are transported into the heated six-position incubator for preconditioning. The sample is simultaneously heated and shaken, in order to facilitate the state change and to reach the equilibrium. A heated, gas-tight syringe is then moved over the incubator and the headspace sample is withdrawn. After sample injection, the syringe is automatically cleaned, by purging with inert gas. Productivity The samples can be run as fast as the GC will allow, because a sample is always ready to be injected when the previous run is completed. In fact, for maximum throughput, EL2000H is equipped with six-position oven that allows the optimization of preparation times. Proven superior headspace technology The high performance, gas-tight heated syringe is a simple and robust system. It eliminates the dead volume and absorption effects, typical of sample loops and transfer lines, which can also impede their detection at very low levels. The EL2000H syringe-only concept allows for sequential injections, even with samples characterized by highly dissimilar features. Even the most chemically active compounds can be analysed, without needing to change any of the sample pathways. Furthermore, it permits adjustable sample volumes without loop changes. No complicated error prone operations, such as vial pressurisation, valve switching, loop filling or heated transfer lines are involved. Therefore, you can extract more data from the samples in less time and at the lowest possible cost per sample.

Vial leakage check - a proprietary technology1 - can be included in your method. In such a scenario the pressure inside vials of the same batch is monitored by an heuristic procedure in order to check against anomalous values that are indicative of a vial leakage problem. Finally, to provide additional robustness of your analysis, going beyond preventive maintenance counters, a system integrity test can be automatically performed in every batch by means of an heuristic procedure. The lowest cost of ownership, the greenest chemistry No carrier gas is needed because gas is used only for purging...
