 K-ASCO    维生素C[L-抗坏血酸]检测试剂盒   40 assays (manual) / 400 assays (microplate) / 400 assays (auto-analyser)                   ¥1936

 

Colourimetric method for the determination of L-Ascorbic Acid 
in foodstuffs, feed, wine and other materials

Principle:
                        (5-methylphenazinium methosulphate)
(1) L-Ascorbic acid + R-H2 + MTT → dehydroascorbate +                                                                                         MTT-formazan + H+
                            (ascorbic acid oxidase)
(2) L-Ascorbic acid + ½O2 → dehydroascorbate + H2O

Kit size:                              * 40 assays (manual) / 400 (microplate)
                                           / 400 (auto-analyser)

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM 
Wave
Spectrophotometer (D-MQWAVE).

Method:                              Spectrophotometric at 578 nm
Reaction time:                   ~ 8 min
Detection limit:                  0.175 mg/L
Application examples:
Wine, beer, fruit juices, soft drinks, jam, milk, dairy products
(e.g. cheese), dietetic foods, baby foods, processed meat, baking
additives, fruit and vegetables (e.g. tomato and potato),
pharmaceuticals, feed and other materials (e.g. biological cultures,
samples, etc.)
Method recognition:    
Methods based on this principle have been accepted by MEBAK
