Petrochemical Color Measurement

From glycol acids to aromatic solvents and chlorinated paraffin, liquid chemicals can be opaque, translucent or transparent, and so require different measurement instrumentation and techniques for successful color measurement. HunterLab offers the right solution, from instrument and software to sample handling fixtures, to ensure consistent and accurate color measurements for every sample, every time.

Petrochemicals include olefins such as ethylene and propylene, and aromatics including benzene, toluene, and xylene. Petrochemicals are the building blocks for a wide range of materials such as solvents, adhesives, plastics, resins, fibers, elastomers, lubricants, and gels.


Petrochemicals can be transparent or translucent and are preferably measured using a transmittance instrument. However, if you also measure opaque samples, you may prefer to select an instrument that measures in both transmittance and reflectance mode.

Most HunterLab spectrophotometers have the versatility to accommodate most applications of color measurement. However, based on 60+ years of experience and a thorough understanding of our customers’ needs and product use, these particular instruments are most suited for this industry application.
