774 Oven Sample Processor


	774 Oven Sample Processor The 774 Oven Sample Processor opens up new possibilities for the automatic determination of water according to Karl Fischer in samples that are either insoluble, react with the KF reagent or cannot be introduced directly into the titration vessel for other reasons. The 774 Oven Sample Processor can be used in combination with all volumetric or coulometric KF titrators supplied by Metrohm. Compared with a conventional KF drying oven the 774 Oven Sample Processor offers many advantages: • The automation of the water determination means a considerably increased sample throughput and increased efficiency. • Considerable savings in time. • Manual sample preparation is reduced to a minimum. • No contamination of the oven and titration cell; this means that there are no carryover or memory effects. • Identical and reproducible analysis conditions for all samples; this is shown by the considerably improved precision of the results. • Much lower reagent consumption as the titration solution only requires changing at infrequent intervals. • Improved water release from the sample as the carrier gas does not pass over the sample but is led directly through it. • The use of hermetically sealed sample vessels means that the samples can be transferred into the vials directly from where they are taken. The PTFE-coated septa guarantee constant and unadulterated water content even after longer storage periods. >> Details...
