901 Titrando for Karl Fischer Titration
Metrohm AG
901 Titrando - The Karl Fischer Titrando for the modern titration laboratory Thanks to its modular concept the Titrando System can be optimally adapted to any application. It meets the requirements of FDA Regulation 21 CFR Part 11. Profit from its intelligence and multiple communication options (USB, RS 232C, Remote)!In addition to the Karl Fischer mode (KFT), this high-end titrator also includes the SET mode, which means that titrations can be carried out to a predefined endpoint. "ITrode ready": The high-resolution, galvanically separated measuring interface - now also with additional digital measuring input for intelligent electrodes «iTrodes» - means that it is also possible to make high-precision pH measurements Transparent operation – thanks to specially adapted dialogs, the Titrando accelerates method development and simplifies routine operation. The large color screen of the Touch Control informs you about the instrument condition and offers uniquely comfortable operator guidance. For operation via a PC the appearance is exactly the same. Numerous worked-out methods and titration examples make familiarization easier. Method templates and calculation formula templates are available for developing your own methods. Extended titration and evaluation parameters open up new applications. More intelligence: The Data Chip of the Dosing Unit contains all important titrant data. Thanks to the sophisticated Liquid Handling, automatic reagent exchange is now also possible in volumetric KF titration. The 901 Titrando works with Dosing Units, which are ideal for handling KF reagents. Parallel titration – a Titrando can work with two titration cells at the same time (requires tiamo).

902 Titrando – pH STAT Titrator and Synthesis Controller
Metrohm AG
The 902 Titrando expands the Titrando system by adding the modes pH STAT titration and controlled dosing. STAT titration The determination of the activity of an enzyme or the monitoring of the release kinetics of antacid drugs requires a titrator that rapidly adjusts a predefined pH value and keeps it constant over a long time period. The 902 Titrando's controller has been optimized for this task and is among the best available on the market. Tandem dosing is a new feature offered by the 902 Titrando. To avoid a break in dosing when the buret is refilled, a second buret takes over the dosing operation without any interruption. This means that fast reactions and those that have a high reagent consumption can be monitored without any loss of accuracy.Controlled dosing The tasks to be performed in the synthesis laboratory differ from those in titration. Typical synthesis work involves maintaining constant a pH value or performing a multiple dosing operation under strictly defined conditions: A preset volume has to be added to a solution during a given time span. During the controlled dosing procedure, the parameters pH (or potential) and temperature are continuously monitored and registered. This results in a complete documentation of the synthesis sequence. Dosing can also be carried out continuously in the tandem mode with two Dosinos. Compatible with all existing sensors Despite its new digital measuring interface and intelligent sensors, the Titrando with combined analogue and digital measuring amplifier also supports conventional sensors. This consists of one high-impedance and one polarised measuring input, a separate reference input and an input for a Pt 1000 or NTC temperature sensor. The resolution of the inputs is 0.1 mV or 0.001 pH. Up to two galvanically separated measuring interfaces can be installed. A new feature of the 902 Titrando is its ability to perform control tasks. External instruments can be controlled by means of freely programmable TTL signals or by communication via RS 232 interface. This opens up the possibility of remotely controlling external heating or cooling apparatus, pumps or similar devices.

859 Titrotherm
Metrohm AG
Thermometric titration is a very versatile determination method and an ideal complement to potentiometric titration. In principle it is suitable for any reaction that produces a sufficiently large temperature change in the sample solution. It is particularly suitable for applications for which no suitable potentiometric sensor is available, for which no suitable reference electrode is available, in which the sample affects the indicator electrode or destroys it, for which no solvent is available that is suitable for potentiometry. The 859 Titrotherm combines innovative sensor technology with Metrohm's titration know-how. The temperature sensor based on semiconductor technology (thermistor), has a short response time of 0.3 s and a high resolution of 10-5 K. This makes the Thermoprobe the ideal sensor for thermometric titration, as it can follow any change in temperature quickly and accurately. Metrohm's Dosino technology has defined a new standard for volumetric titration. The Dosing Unit with its drive motor is mounted on the reagent bottle and thus guarantees maximum precision with minimum space requirements. The clearly laid out Titrotherm software allows adaptation of the screen view to the particular method parameters and thus provides rapid access to important commands or parameters. The endpoints are determined by calculating the first and second derivatives of the titration curve; by means of additional optimization parameters, the reproducibility can be improved even further.

860 KF Thermoprep
Metrohm AG
Thermal sample preparation in Karl Fischer titration. For various reasons many substances are not suitable for a direct Karl Fischer titration: – They release their water only slowly – The water is released at high temperatures only – The substances are poorly soluble in alcohols – They undergo side reactions with KF reagents – They contaminate the titration cell or the electrodes By using the KF oven method the above-mentioned problems can be avoided. The substance under investigation is heated in a hermetically sealed vial in the oven. The water vapor released is transferred to the titration cell by a carrier gas. This means that no noxious solubilizers have to be used, side reactions as well as matrix effects are absent and the contamination of the titration cell is avoided. Depending on the sample’s water content, the determination can be carried out either by coulometric or volumetric Karl Fischer titration.

856 Conductivity Module
Metrohm AG
The 856 Conductivity Module is the new conductivity meter from Metrohm. It measures with state-of-the-art conductivity measuring cells – five-ring measuring cells. They achieve high linearity without platinization of the cell and are maintenance-free. The five-ring cells also yield accurate measurement data irrespective of the immersion depth. Broad range of applications The 856 Conductivity Module is versatile and can be used: - to extend a Titrando with an additional measurement input for pH or ion measurement - as an integrated conductometer in conjunction with the software packages PC Control or tiamo™ (from version 2.0) - as a stand-alone conductometer together with the 840 Touch Control operating unit - as a fully automated conductometer combined with the 814 USB Sample Processor or 815 Robotic USB Sample Processor XL Thanks to the galvanically separated measuring input, pH and conductivity measurements can now be performed simultaneously in the same sample vessel. Regardless of the application – measurements always meet GLP and FDA requirements. For use with the latest conductivity measuring cell technology The 856 Conductivity Module’s new five-ring conductivity measuring cells provide a wide linear measuring range. In contrast to four-ring cells, the electrode can be fully immersed in the sample solution. In a stirred solution, this results in faster mixing within the measuring cell. Thanks to the removable cap, the conductivity measuring cells are very easy to clean. Plug-and-play functionality for numerous peripheral devices Two USB and four MSB ports make the 856 Conductivity Module incredibly flexible. Plug-and-play functionality means the user can connect a multitude of devices: - printers, sample changers, barcode readers, etc. - up to four stirrers and four 800 Dosinos
