899 Coulometer Mobile coulometer for water determination anywhere you want • Extremely small & compact • Maximum flexibility due to independent power supply • Automatic start of titration 899 Coulometer – the smallest and most compact Metrohm coulometer ever 02 The 899 Coulometer couldn’t be any smaller and more It may be small, however, the 899 Coulometer does not compact: With dimensions of 144 x 112 x 282 mm compromise on performance. Water contents can be de- (W x H x D) the new Metrohm coulometer needs no more termined with utmost precision down to trace levels. benchspace than a sheet of DIN A4 paper. That’s the result of smart design by Metrohm engineers: • The 899 Coulometer is equipped with an integral magnetic stirrer. You no longer need to connect an external stirrer. • Support rod? Not necessary either. An integral holder ensures that the titration cell stands securely on the top of the 899 Coulometer. Small footprint and compact dimensions: the 899 Coulometer 03 Determine water content anywhere you want You are in the field and need to know the water content of a sample. The laboratory is far and waiting for results is out of the questions. There is no socket around to plug in a power cord either. No problem with the mobile 899 Coulometer. Simply rely on the instrument’s independent power supply that comes with the optional Power Box. It contains a set of rechargeable batteries that last for hours of uninterrup-ted and reliable operation. The 899 Coulometer gives you full independence as you can now perform coulometric determinations of the water content on the spot anywhere you want! 899 Coulometer with an optional Power Box for battery operation Automatic start of titration 04 It can easily happen that the sample is put into the titration vessel before one has started the titration. In this case the conditioning continues until the reagent has again been titrated dry. Recalculations are impossible and the analysis has to be repeated. That means wasted sample, lost time and more stress. With the 899 Coulometer that cannot happen. The automatic start ensures that the titration begins automatically as soon as sample is put into the titration vessel. Thermal sample preparation: the oven method It may be small but the mobile 899 Coulometer provides The oven method is recommended for such samples. 05 the same capabilities as the larger Metrohm coulometers. Here, the water contained in the sample is first removed This includes thermal sample preparation, and even fully by heating the sample and is then transported by a dry automated, if required. carrier gas into the titration cell, where the titration takes place. Not every sample can be put into the titration vessel directly. There are various possible reasons for this: The 899 Coulometer can be operated with either a man-ual oven (860 KF Thermoprep) or an automated oven • limited solubility system (885 Compact Oven Sample Changer). • secondary reactions with reagents • slow release of water from the sample • release of water only at higher temperatures • dirt in the titration cell 899 Coulometer and 860 KF Thermoprep 899 Coulometer and 885 Compact Oven Sample Changer 899 Coulometer at a glance 06 Water contents 10 µg ... 200 mg Number of predefined user methods 3 Number of possible stored user methods 100 Routine/Expert mode Yes Automation with 885 Compact Oven SC Yes Live curve during titration Yes Auto start after sample has been added Yes Integral magnetic stirrer, and also Stirrer.
