Liquid Handling

The manual transfer of liquid samples forms part of the everyday work of an analytical laboratory, so the precision of the transfer plays a decisive part in the quality of the analysis results.

Liquids characterized by their low boiling point or high viscosity therefore pose a number of challenges when it is a matter of transferring the required volumes as precisely and exactly as possible, as is the case when preparing calibration standards and quality control samples.

Furthermore, additional sample preparation steps such as filtration, incubation or centrifugation must also be incorporated into the processes.

Transfers of this type, along with the associated sample preparation steps can be automated using a GERSTEL MultiPurposeSampler (MPS). This ensures that the resulting data are of high quality and does away with the need for analysts to perform laborious manual tasks in which there is no tolerance for error.

In addition to a large number of features to facilitate the transfer of liquids, the autosampler functions controlled by the MAESTRO software also include additional techniques, such as tempering, filtration, mixing, shaking, incubation, evaporation or centrifugation. An analytical balance to verify the weight of the liquid transfer can even be incorporated.

The autosampler can be configured as part of a gas chromatography (GC) or liquid chromatography (LC) system or can be used independently as a bench-top workstation.
