• Fritted (Diaphragm) Generator · Anode/anolyte and cathode/catholyte separated by glass diaphragm · Prevents anode-generated iodine from being reduced to iodide at the cathode · Ideal for extremely low water content, high accuracy demand, nitrogenous compounds and easily reduced samples • Fritless (No Diaphragm) Generator · Uses one easy-to-replace Karl Fischer reagent · Lower and more stable drift rates · Easier cleaning of generator cell Selectable Endpoint Criteria The HI904 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates. Multistage Cell Preparation A pre-titration stage eliminates residual water present in the solvent and the cell, providing a reliable baseline start to analysis. Standby mode then keeps the solvent dry between titrations and when the titrator is not in use. Interface & Display Detailed Titration Graphs A real-time titration curve can be displayed during each titration; this feature is useful when new methods are tested or when a procedure requires optimization. Interactive Color Display A large, color LCD screen clearly shows the chosen titration method along with results, units, drift rate, and mV value. Simple and Quick Navigation Virtual key selections present on the display allow for simple and quick navigation between screens and menus without getting lost in a nest of information. Data & Storage Customizable Titration Reports Each titration report is fully customizable so users can ensure they are storing and filing the appropriate data required for their application and procedures. Flexible GLP Management All necessary GLP (Good Laboratory Practice) information can be recorded with each sample including: sample identification, company and operator name, date, time, electrode ID codes, and calibration information. Effortless Data Transfer Data can easily be transferred to a USB flash drive or PC with the Hanna HI900PC application software. The USB port allows for the transfer of titration methods, titration reports, and software upgrades via USB flash drive. Methods of Analysis Customizable Methods The HI904 can store up to 100 user-defined or standard titration methods. Each method may be customized and optimized for performance based on application and user requirements. Titration Method Support Onsite installation, training, and customization is available from one of our Applications or Service experts. Hanna offers continued support via phone or webinar for any questions you might have along the way. Adaptable Standard Methods Our technical experts can program and customize standard methods developed by such affiliations as ISO, ASTM, AOAC, AOCS, EPA, and more directly onto your titrator. Ask our Sales Consultants which standard methods are possible with our HI904 Karl Fischer system. Connectivity and Functionality Configurable Balance Interface Sample size may be automatically entered from any laboratory analytical balance with a RS232 serial output saving time and labor. Multiple Peripherals Users can print reports directly from the titrator using a standard parallel printer. An external monitor and keyboard may be attached for added versatility, as well as an analytical balance for automatic sample mass entry for titrations. 4 Titration 4.49 www.hannainst.com |
