Metrohm has unveiled the 872 Extension Module Liquid Handling Unit, which can be fitted to the 850 Professional IC.
The 850 Professional IC represents the third generation of IC from Metrohm that offers reliable, reproducible results run after run, with little or no down time required for essential maintenance.
The 872 is an extension tool for upgrading all 850 Professional IC instruments.
It enables an additional dual-channel peristaltic pump, six-port injection valve, as well as a 10-port selector valve to be installed into the 850 Professional IC.
The 872 Extension Module Liquid Handling Unit extends the capabilities of Metrohm Inline Sample Preparation (MISP).
The 10-port valve could be used for example to provide at-line analysis if the IC was located close to a number of different sample sources.
The mixing vessel could be for example for pH modification on a sample ahead of analysis or a pre-column reaction through the addition of an auxiliary solution.
The system is flexible and open ended, it would be possible to use the setup for dilution or spiking of the sample.
Using Metrohm Dosino technology, it is possible to aspirate and dose accurate volumes of solutions around the IC system as appropriate.
Short capillary connections keep the rinsing volume low, so that liquid handling becomes even faster and more reproducible.
The 872 Extension Module Liquid Handling Unit is fully controlled by the MagIC Net software, and even complicated liquid handling can be automated and incorporated into the working method.
