总亚硫酸盐检测试剂盒（酶法）

英文名：Total Sulfite Assay Kit (Enzymatic)

货号：K-ETSULPH

规格：50 assays (manual) / 500 assays (microplate)

The Total Sulfite (Enzymatic) test kit is a simple, highly specific and reliable, enzymatic method for the measurement and analysis of total sulfite (as SO₂) in wines, beverages, foodstuffs and other materials.

Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4^oC.

Suitable for manual, auto-analyser and microplate formats.

UV-method for the determination of Total Sulfite (SO₂^2-) in
beverages,foodstuffs and other materials

Principle:
(sulfite oxidase)
(1) SO₃^2- + O₂ + H₂O ↔ SO₄^2- + H₂O₂

(NADH – peroxidase)
(2) H₂O₂ + NADH + H⁺ → 2 H₂O + NAD⁺

Kit size:                            50 assays (manual) / 500 (microplate) 
                                          / 588 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Total assay time:              ~ 30 min
Detection limit:                 0.3 mg/L
Application examples: 
Wine, beer, fruit juices, soft drinks, jam, fruit and vegetables,
pharmaceuticals and other materials
Method recognition:     
Methods based on this principle have been accepted by DIN, EN,
MEBAK and NMKL
