Acceptable matrices

Transparent oils

Unacceptable matrices

Cloudy oils

Limit of quantitation

The yellow scale ranges from 1.0 to 70.0, the red from 0.1 to 20.0.

Common Color Analysis (Lovibond) Test Testing Questions

Lovibond is a color analysis specific to clear liquids. For the testing performed at Medallion Labs, this testing is specific to fats and oils that are clear liquids at room temperature (can’t be cloudy or partially solidified).

The sample is put into a small cuvette and placed into the instrument. The instrument measures the amount of red and yellow colors in the sample and compares against a series of calibrated standards to report the color values for that sample. The Red/Yellow Lovibond scale is particularly useful for measuring how refined an oil is, if the oil is in spec for appearance, or if the oil has aged.

The Lovibond Color test at Medallion Labs measures the amount of Red and Yellow Colors in a sample.

The instrument works by shining light through the sample, while also comparing against standard color filters. The sample is compared against the color standards until it matches.

The Red/Yellow Lovibond scale is particularly useful for measuring how refined an oil is, if the oil is in spec for appearance, or if the oil has aged.
In a more general sense, color and perception of color is a construct that can vary across individuals, experience, and preferences. For example, would two people pick out the same paint chip that is ‘sky blue’ in a paint store?
Because of this, the main benefit for any color measurement is that it takes a complex description and attempts to summarize in a few defined and objective values. This allows for precise quality control of your product in relation to color.
