PRINCIPLES & FEATURES UV Tests NZYTech test kits are based on enzymatic reactions and performed using spectrophotometric methods. The principle of the enzymatic tests is based on the NAD(P)+/NAD(P)H system and uses highly pure enzymes engineered to display a premium performance. The enzymes used in these analytical kits produce or consume NAD(P)H, which strongly absorbs the UV radiation at 340 nm (extinction coefficient of 6300 M-1cm-1). Absorbance at 340 nm NADH NADPH NAD+ NADP+ NADH NADPH NAD+ NADP+ Reaction Time Colorimetric tests The principle of the enzymatic tests based on a chromogenic...
