Titrator has a sophisticated control algorithm that has been adapted to the characteristics of the Karl Fischer reaction to ensure fast, highly precise results
The Karl Fischer water determination is one of the most frequently applied laboratory methods.
In contrast to other water determination methods, it is specific as well as rapid and requires no expensive equipment.
With an application range of 0.1% to 100% water, the volumetric Karl Fischer titration is used in a wide variety of fields.
including determination of water content in food, cosmetics, or pharmaceutical products.
The 841 KF Titrando has a sophisticated control algorithm that has been adapted to the characteristics of the Karl Fischer reaction to ensure fast, highly precise results, says Metrohm.
Choose between a polarized alternating current (Ipol) or a defined voltage (Upol) to be applied to the electrode.
The Set mode performs potentiometric titrations to a preset endpoint (pH value or potential).
Typical applications of the Set mode are the determinations of p and m values in water analysis.
Ready-to-use methods for pH measurement and electrode calibration are pre-installed.
The resolution of the electrode input is 0.001pH, identical to the precision of a pH meter.
In addition, the electrode characteristics and the calibration history of each sensor are memorised.
As with any pH meter, users can also measure potential (mV) and temperature.
Different reagents may require different method parameters.
The 841 KF Titrando lets users select the appropriate method for each type of reagent.
For example, the on-screen icons show at a glance whether the instrument is still busy conditioning or conditioning is complete and the water determination can start.
The electrode test and safety stop feature prevent cell run-over during conditioning.
For example, if the electrode is not connected properly or the titration cell is very humid, then conditioning is stopped after a given time or after a given volume of KF reagent is added.
Thanks to its modular concept, Titrando can be optimally adapted to any application, says Metrohm.
It meets the requirements of FDA Regulation 21 CFR Part 11.
The 841 KF Titrando works with Metrohm's Dosinos - the design of the buret and stopcock minimises crystallisation, making them ideal for handling KF reagents.
If Titrando will not be used for several days or more, use the Prep feature to empty the reagent in the buret and tubing back into the reagent bottle.
Not only does this prevent KF reagent crystallisation, it also saves the expense of purchasing more reagent for the next titration.
The Smart Chip in each Dosino's buret memorises reagent information such as concentration, standardisation value, and history.
That means every time a buret is connected to the system, Titrando immediately and automatically knows the identity and concentration of the reagent.
And with the sophisticated Dosino, automatic reagent exchange of the solvent in the Karl Fischer vessel is now possible for volumetric KF titration.
Touch Control or PC control.
Up to three Titrandos can be controlled by a single Touch Control.
Tiamo software offers expanded data storage, a user-friendly interface, and a powerful database with sorting and filtering for easy data retrieval.
Titrando will connect directly to the PC with Tiamo: connection to the computer is USB controlled, so it's a simple, plug-and-play installation.
This setup does not require the purchase of the optional Touch Control unit, thereby saving money.
For data storage and transfer, Titrando is state-of-the-art.
The data from Titrando can be printed out directly to a USB-connected printer; data (and methods) can also be stored directly on a PC data card.
Tiamo software offers additional storage options, such as hard drives, external drives (CD-Rom, zip disk, floppy disk), and internal network drives.
Regardless of the type of data storage and retrieval chosen, all information regarding the system's hardware connections and the method parameters is stored with each individual analysis.
Titrando can send a machine-readable report directly to a network via Metrohm's Lab Link (optional) - without connection to a local PC.
Data can be sent directly from Titrando to Lims, Lan, or archiving programs such as NuGenesis, eRecordManager, and CyberLab for long-term storage.
