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 liquid handling with the built-in six-way injection valve and the bidirectional peristaltic pump one system ­ numerous possibilities the 838 advanced ic sample processor comes in five versions the application determines which sample processor is the right one 838 advanced ic sample processor 2.838.0010 equipped with a dual-channel peristaltic pump the 838 advanced ic sample processor acts as an automatic sampler for the ic system the standard sample rack accommodates up to 148 samples and has three rinsing stations twelve further sample racks for different vessel sizes ranging from 2.5 ml to 250 ml are preprogrammed sealable sample vials with very small volumes 0.5 ml can also be used furthermore it is possible to freely define sample racks and to access an external sample position for example for urgent samples the sample processor can be controlled as an independent instrument by means of an external keypad option or by the metrodata ic net software advanced ic injection sample processor 2.838.0020 this sample processor comes with an integral metalfree six-way injection valve that opens up a whole range of applications the 838 can take over for example sample injection for the 817 bioscan or supply the second valve for a combined anion-cation system within the framework of the metrohm inline sample preparation techniques for example inline matrix elimination inline neutralization or inline calibration the second valve is now readily available on the sample processor the dual-channel peristaltic pump can be used for various tasks such as sample injection or for conveying the transfer solution its velocity and flow direction can be perfectly adapted to the application at hand advanced ic filtration sample processor 2.838.0210 sample filtration is a routine task in the analytical laboratory inorganic particles humic acids bacteria or algae are among the contaminants that have to be removed before the analysis as they are prone to block the separation column one-way syringe filters are expensive and their application is problematic filter caps pushed into the sample vessel by the sample changer are obsolete similarly expensive and limit the application range the solution today is ultrafiltration the samples are placed onto the sample rack as usual and processed by the 838 advanced ic filtration sample processor in the ultrafiltration cell the sample solution flows underneath a membrane on whose upper side the filtrate is aspirated off transferred to the sample injection valve and finally injected sample transfer is performed by the built-in dual-channel peristaltic pump ultrafiltration is ideal for samples with slight to medium contamination such as drinking water surface water and waste water digestion solutions and extracts to mention just a few examples 838 advanced ic sample processor
