Accurate color measurement of liquid chemicals is crucial for quality control, identifying chemical reactions, monitoring product characterization, ensuring safety, and facilitating research and development. Konica Minolta offers a range of high-precision spectrophotometers, such as the Spectrophotometer CM-5, the Spectrophotometer CM-3700A, and the Spectrophotometer CM-36dG, ideal for precise color measurement of liquid chemicals. These instruments can accurately measure and analyze a wide range of water or oil-based liquid chemical products, from opaque to translucent and transparent. The obtained color data is repeatable and traceable, enabling seamless reporting and effective communication with customers and suppliers.

Color spaces such as CIE L*a*b* and L*C*h are commonly employed in color control applications. However, when it comes to routine grading of liquid chemical products, it is often more convenient to utilize widely recognized industrial standard color indices like APHA/Hazen/Platinum-Cobalt, etc. The innovative and versatile Konica Minolta Spectrophotometer CM-5 can express the color of liquid chemicals in major colorimetric like CIE L*a*b* and also various industrial standard color indices, including Gardner Color Scale, APHA/Hazen/Platinum-Cobalt, and Iodine Color Number, among others.

Color measurement is crucial for quality control and process management in the chemical industry. It ensures consistent product quality, batch-to-batch uniformity, and regulatory compliance. Konica Minolta offers a diverse range of accurate and traceable color measurement solutions that support and assist chemical companies in maintaining quality standards for powdered chemicals. Among these, the Spectrophotometer CM-5 and Spectrophotometer CM-36dGV are capable of measuring the color, including whiteness, of powdered chemicals. These instruments are accompanied by a range of accessories that ensure consistent and controlled preparation of powdered chemical samples.

Fluorescent materials often contain optical brightening agents (OBAs) or fluorescent whitening agents (FWAs) that can significantly affect color and whiteness measurement. Ensuring accurate results when evaluating materials with OBAs requires the use of spectrophotometers that can account for the UV content. The Konica Minolta Spectrophotometer CM-36dGV and Spectrophotometer CM-26dG are such instruments whereby they are equipped with UV full xenon lamps and UV cut xenon lamps, enabling precise measurement of both the base material and the effect of OBAs.
