Intended use

UV-method for the determination of sulfurous acid (“total SO2“) in foodstuffs and other materials.

General Information

The “Yellow line” kits are produced by Roche Diagnostics, previously Boehringer Mannheim, with more than 40 years experience in the production of the enzymes, which are the key element of each test. The Roche test kits have been used and validated worldwide for several decades, with many corresponding publications. They have been selected as reference methods by many international organizations (e.g. AOAC, IFU, IDF, ISO and OIV) and they are still the gold standard today.


  • Reference quality for more than 40 years.
  • Approved by national and international organizations.
  • 31 tests for all requirements in the food industry.

LOQ (Limit of quantification

The detection limit is calculated via the Lambert-Beer law and depends on the application used. For example, if sample volume v = 0.500 ml and Delta A = 0.050 (A), then detection limit = 3 mg/l. This limit can be improved proportionally by increasing the sample volume.
