Autosampler For Spectrophotometric Analysis

A general liquid handling application is to use a liquid handler as an autosampler for a spectrophotometer. The traditional manual method for filling a flow-through cuvette is to use a peristaltic pump (a sipper) to draw the sample through the cuvette. This can easily be replicated using a Gilson GX liquid handler.

Example applications are:

• The determination of chlorophyll in surface water

• The Molybdenum Blue method for determination of phosphate in Coca Cola

• Protein Matter and Lipolysis Index in milk analysis

Applications and customers require different levels of traceability of the samples, as well as reporting. This technical note will explain different hardware configurations, as well as software options, to use Gilson liquid handlers with TRILUTION® LH Software as autosamplers for spectrophotometric analysis.
