875 KF Gas Analyzer Straightforward determination of water content in liquefied and permanent gases A fully automated solution for one of your most critical applications! 02 Accurate, reproducible results at the touch of a bines the inherent benefits of coulometric Karl screen: The 875 Karl Fischer Gas Analyzer is a fully Fischer titration with a robust sampling system automated solution for reliable water determina-that meets the need for safety and convenience of tion in liquefied and permanent gases. It com-routine users in the oil and gas industry. Example applications Use the 875 KF Gas Analyzer to perform routine analysis of the following gases (list not complete) • Propane, propene, liquefied petroleum gas (LPG), butane, butadiene, isobutene • Dimethyl ether (DME) • Chlorinated hydrocarbons: methyl chloride (chloromethane), ethyl chloride (chloroethane), vinyl chloride • Refrigerants and propellants: various chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) 03 Key features & benefits Uncompromising safety • Robust shelter with strict separation of the gas handling system from the electronics • Can handle gas pressure of up to 40 bar • Inlet filter protects the system from particles providing for a long system life • Everything at a glance: The optional touch screen can be installed right on the device Complete Automation • No manual intervention necessary thanks to auto matically controlled solenoid valves • After the measurement is before the measurement: The system conditions itself with dry nitrogen after each measurement and is immediately ready for the next sample • Optional 20 mL buret for simple, fully automated change of reagent • Predefined methods in tiamo TM for straightforward operation Accurate and reproducible results • Integrated high-end Metrohm coulometer for direct and accurate water determination • Reproducible results due to precise sampling by means of mass flow controller • Optional 20 mL buret for simple and semi-automatic cleaning of the system through guided cleaning steps to prevent carry-over Versatile use • Besides measuring liquefied gases, you can use the coulometer as a standard system and measure liquids via direct injection. Optional further automation Equipment for automatic reagent change and System rinsing equipment methanol addition Samples with higher boiling impurities, with oil residues, Due to the constant gas flow through the coulometric or with a tendency to polymerisation may accumulate in titration cel , methanol evaporates and must be replaced the system. With this optionally available set, these can regularly. This optionally available set contains everything be easily flushed out of the system. A method guides the to automate this methanol addition as well as complete user through the individual steps to bring the system refilling of the coulometric titration cell. back to its original state.
