Metrohm OMNIS Sample Robot fully automated TAN/TBN titration

Metrohm presents a fully automated solution for the determination of total acid number (TAN) and total base number (TBN) in up to 112 samples. The process is based on the OMNIS Sample Robot and addresses the needs of QC laboratories in the petrochemical industry as well as contract laboratories looking for an efficient solution to cope with high sample loads.

On the OMNIS Sample Robot, the entire analysis is performed in a closed system, so there is no risk of physical contact with solvents or reagents at any time. For reproducible results, the sensor of the system is rinsed and conditioned after each determination. For safety and convenience, the system can be operated in any standard size fume hood.

The robot can be expanded in three steps from size S to M to L, which accommodates up to 112 samples evenly distributed over seven racks. The product is flexible: racks with urgent samples can be prioritised and placed on the Sample Robot while the system keeps analysing.

Maximum throughput on the robot is achieved using the possibility to perform up to four titrations in parallel at four workstations, saving up to 60% in time compared to titration at a single work station.
