Title:
SYSTEM AND METHOD FOR LIQUID DELIVERY EVALUATION USING SOLUTIONS WITH MULTIPLE LIGHT ABSORBANCE SPECTRAL FEATURES
Document Type and Number:
WIPO Patent Application WO/2009/126224
Kind Code:
A3
Abstract:
A system and related method for improved liquid delivery evaluation uses a solution containing one or more dyes such that the solution exhibits multiple distinct detectable light absorbance spectral features for calibrating or testing over extended volume or dilution ranges. The system includes: a photometric instrument capable of measuring optical absorbance at multiple wavelengths; a sample solution to be dispensed using the liquid delivery system whose performance is being tested or calibrated; and vessels with diluent solution. The sample solutions contain a dye, chosen so that multiple distinct detectable light absorbance spectral features can be distinguished for volume or dilution ranges of interest. The concentrations of the dyes may be chosen so that a large volume delivery device, and a small volume delivery device, are calibrated with the same sample solution but using a different spectral feature with a high absorbance per unit pathlength.
