  • High sensitivity and low detection limit (0.6 ppm ascorbic acid)
  • A rapid, robust chemical assay complete in 25 minutes
  • High reproducibility 

The MaxSignal® Ascorbic Acid Assay Kit uses a specific visible, colorimetric reaction to detect ascorbic acid in food samples: ascorbic acid first reduces an electron carrier (PMS). This compound then reduces MTT to produce a colored MTT formazan product. This conversion, measured at 578 nm, is proportional to the level of ascorbic acids in the sample.

The absorbance of each sample at 578 nm is measured using a spectrophotometer in a cuvette (or plate reader). The concentration of ascorbic acid in each sample is then directly determined from the change in absorbance at 578 nm within 30 minutes time. The assay offers both a cuvette-based format and a microtiter plate format for high-throughput sample analysis.

This kit is manufactured to the international quality standard ISO 9001:2008.
