Color measurement of liquid chemical products

 

From glycolic acid to aromatic solvents to chlorinated paraffin, chemicals can be opaque, translucent or transparent and therefore require different measuring instruments or measurement techniques for successful color measurement. HunterLab offers the right solution, from equipment and software to sample holders, to ensure consistent and accurate color measurement for every measurement process and every sample. Oils, varnishes, fatty acids or resin solutions and adhesives often require special sample handling and, in addition to color values, indices (Gardner, Saybolt, Hazen, etc.) and turbidity values are also determined. HunterLab color measuring devices meet every requirement.


The world's leading chemical producers rely on solutions from HunterLab. Precise and repeatable measurement results ensure the quality and consistency of finished products, as well as the raw materials used, across the entire supply chain.

Application example

"Color measurement of liquid chemical products with the Vista spectrophotometer"

In the chemical industry, the precise determination of the color of transparent liquid products such as benzene, ethylene and propylene, as well as solvents and various lubricating oils such as motor oil is very important in development and quality management. To qualify the color of petrochemicals, solvents and lubricants, exact color measurement in transmission is the appropriate approach. Some of these products use internationally defined color numbers such as: B. APHA/PtCo/Hazen, Gardner, Saybolt and others worked. HunterLab color measurement offers the perfect solution to determine exact color values and at the same time the appropriate color number.


The task

In addition to the precise measurement of the CIE L*a*b* color values, the reliable determination of various color numbers is also desired when examining petrochemical liquids and oils. The color measurement should be carried out as simply and quickly as possible.

Available color numbers:


APHA/Pt-Co/Hazen

Gardner

Saybolt

ASTM D1500

AOCS

DO

Iodine

The solution

With the Vista spectrophotometer, transparent, liquid chemical products can be precisely measured in transmission. When measuring, you can optionally have all the color numbers commonly used in the chemical industry displayed immediately in addition to the usual color scales (see box). Macro, semi-micro and ultra-micro cuvettes (made of glass or plastic) with a path length of 1 cm are usually used for color measurement. This means that all color numbers can be measured and output in the desired (standard) standard layer thickness.


The measurement is very simple:

    Fill the cuvette with liquid. Insert the cuvette into the holder. Trigger the measurement. Read the measured values on the device
