Mercury Analysis by Automated Photometric Titration

Mercury Analysis by Automated Photometric Titration

25 Aug 2015

This application note describes a method for the automated analysis of mercury content using photometric titration. The 907 Titrando from Metrohm was used, combined with the 815 Robotic USB Sample Processor XL.

815 Robotic USB Sample Processor XL

Metrohm AG

The highly efficient Robotic USB Sample Processor XL with two stations and four pump connections carries out complex laboratory automation tasks in combination with a Titrando. Together with the Swing Head the capacity is increased, for example, to 100 x 75 mL samples. The daisy-chain function of the MSB connections allows the direct control of Dosinos for «extended liquid handling» and/or of stirrers; including control cable. For rinsing the titration vessels and electrodes and for aspirating off the titrated solution up to four external peristaltic or membrane pumps can be connected. The methods are programmed with the handy Touch Control or PC-controlled - with the tiamo titration software. • Large sample volumes and large numbers of samples • Parallel operation • Automated liquid handling - pipetting • Karl Fischer automation • Automatic sample preparation • Two external titration stations
