The color of transparent liquids is critical as a change can indicate contamination or impurities in the raw material, process variations caused by heating and oxidation, or degradation of products exposed to weathering over time. Visual tests have been established by comparing the sample to a known standard. Today, objective measurements can be done with color spectrophotometers that give reliable data on a consistent basis. Besides degree of yellowness, such spectrophotometers also describe color differences three dimensionally: red/green, yellow/blue and light/dark differences.
The LCM IV is a reliable color instrument which replaces conventional visual color evaluation with an objective measurement. It is ideal for routine production control of clear, transparent liquids like resins, adhesives and solvents.
