Multichannel Verification System (MVS): A Dual-Dye Ratiometric Photometry System for Performance Verification of Multichannel Liquid Delivery Devices

Abstract

Artel has developed the Multichannel Verification System (MVS), a photometric method for verifying the performance of automated multichannel liquid delivery equipment. 1 On the basis of Artel's patented Dual-Dye Ratiometric Photometry method, the MVS determines both the accuracy and precision of each individual channel of a multichannel liquid delivery device. The MVS verifies aqueous volumes of 2–200 μL, produces results that are traceable to national standards, and can be applied to a wide range of instruments. It is important that the MVS is a robust system that is convenient to use in the laboratory environment so that the volumetric performance of automated liquid-handling equipment can be verified frequently without causing unnecessary delay in use of the instruments for their intended applications.
