838 Advanced IC Sample Processor

The 838 Advanced IC Sample Processor represents the latest generation of high-performance sample processors for ion chromatography. It sets new standards regarding flexibility, sample preparation, liquid handling and sample throughput. Sample volumes ranging from 500 µL to 250 mL can be processed, 999 sample positions can be accessed; with up to three Dosinos, two membrane pumps and a bidirectional peristaltic pump the possibilities offered for liquid handling are virtually unlimited.

More than thirty years of experience in sample changer design – the first Metrohm sample changer was marketed in 1973 – guarantee the usefulness of our products. With the 838 Advanced IC Sample Processor, Metrohm now presents an instrument that is extremely user-friendly and allows substantial savings.

Enjoy the weekend while the 838 works for you!

Automation in ion chromatography helps to optimally organize not only your working hours but also your spare time. There is no reason any more to waste time for routine work such as manual sample injection or manual sample preparation. The sample processor takes over all these tasks. The 838 Advanced IC Sample Processor's sample rack accommodates up to 148 samples. If we assume the analysis time for one sample to be 20 minutes, the sample processor will take care of these 148 samples over the weekend.

« Human touch» or high precision?

In most cases, manual sample injection means increased standard deviation of the results. Systems equipped with Metrohm sample processors yield excellent reproducibilities. If the aim is to obtain highly accurate results and to automate and document all the sequences, the «High End» 838 Advanced IC Sample Processor is the instrument of choice.

One system – numerous possibilities

The 838 Advanced IC Sample Processor comes in five versions. The application determines which sample processor is the right one.
