Process chemicals can be analysed on-line
Metrohm has combined the best aspects of laboratory and online systems to produce the 875 ProcessLab: a fully customised, automated at-line system for analytical testing.
Determining water levels in lubricating oils
It is impoirtant to determine the presence of water in machinery lubricating oils, which is why Metrohm is offering its 831 KF Coulometer to give reliable results over a long period.
It is equipped with the quick aliquoting device 6.9958.007, which transfers 100 mL sample to an external titration vessel for the fully automated analysis.
Up to 59 water samples can be analyzed in one series.

Stand-alone setup Detailed Procedure The water analysis involves the determination of alkalinity and water hardness by means of an automated system consisting of a 789 Robotic Sample Processor XL in combination with a 799 GPT Titrino.
The Aquatrode Plus is used as the indicator electrode for the alkalinity determination; the water hardness titration is indicated by a Ca ISE combined with the reference system of the Aquatrode Plus.
The conductivity measurement is carried out with the 712 Conductometer and a conductivity cell that is used instead of the titration equipment.
The standard rack used accommodates 59 beakers with a volume of 120 mL.
The samples are stirred by a propeller stirrer.
The new quick aliquoting device 6.9958.007, an overflow buret, transfers the sample to the external titration vessel using the built-in pumps of the 789 Robotic Sample Processor XL.
After the titration the built-in membrane pumps of the 789 Robotic Sample Processor XL guarantee efficient aspiration of the spent solution and thorough rinsing of the titration equipment.
Data collection is realized by the Metrodata Software Vesuv 3.0 that is included in the 799 GPT Titrino's standard accessories. Request a free brochure from Metrohm UK ...
