The VerraGlo Peroxide Number* Color Test for petrochemicals & renewable diesel can determine the Peroxide Number (mg/Kg) with only 3 drops of fuel, and comparison of color development to a standard color chart, or using a reflectance colorimeter. The color difference between PN 1.1 and 2.3 is easily discernible visually and with a colorimeter.

An alternate format of this test can be used to measure the Peroxide Value in edible oils (milliequivlants/Kg).

Advantage of the VerraGlo™ Peroxide Number Color Test Over Other PN Methods:

• Can be conducted with 3 drops of fuel (ca. 150 uL) with results in about 10 minutes.

• Does not use or generate toxic solvents that are expensive to purchase, must be used under a laboratory fume-hood, and that have to be disposed of as hazardous waste.

• The method uses no laboratory glassware, no solvents and no cleanup;  the sample plate is disposable.

• Has excellent sensitivity, precision and readability in the low PN range (Limit of Quantification of 1.1 mg/Kg).

*The peroxide number values used on this page represent the total hydroperoxide oxygen content in mg/Kg fuel.
