Test principle
The test principle is shown as followings:
 
There is a strong absorption peak of red quinochrome at 520 nm, and the absorbance is proportional to the concentration of CHOL.
	
Product Features
1. Linear range of CHOL level: [0.20, 10.40] mmol/L
Linear correlation coefficient ∣r∣≥0.990
Linear deviation ≤ ± 10.00%
2. Absorbance of blank ≤ 0.30
3. Sensitivity
The change in absorbance (ΔA) ≥ 0.01 while testing the specific CHOL sample of concentration of 5.20 mmol/L.
4. Accuracy
Relative deviation is within ±10%.
5. Precision
