Hamilton Company Microlab 600 dilution of beer and wine for alcohol analysis

Click2Contact

There are several techniques for measuring the alcohol concentration of beer and wine. For facilities with numerous samples to process, the technique of choice is gas chromatography (GC). To prepare samples for analysis by GC, they must first be diluted and spiked with an internal standard. The Hamilton Microlab 600 accomplishes this task in a single step, delivering the diluted sample directly into the GC vial.

Alcohol testing is regulated and requires reliable and traceable methods. The Microlab 600 is a highly precise syringe pump with a graphical user interface and comes complete with a calibration certificate that is traceable to N.I.S.T. standards.

This positive displacement system provides better than 99% accuracy, independent of a liquid’s viscosity, vapour pressure and temperature. The inert fluid path minimises sample carry over and improves compatibility with harsh chemicals. Dilution and dispensation methods are stored on the system and recalled prior to use, ensuring that the same method is followed day in and day out. The user simply triggers the hand probe to aspirate or dispense the liquid. By automating the pipetting functionality, technique-dependent variability is minimised.
