Testing Principle

   1. The testing principle of GA concentration are shown as followings:

2. During the measurement of ALB concentration, positively charged ALB molecules reacted with negatively charged BCG molecules, forming the blue-green complex which shows absorption at the wavelength of 600 nm. The absorbance of this complex is proportional to the concentration of ALB.
ALB concentration can be calculated by comparing with the standard solution prepared in the same method mentioned above.

Product Features

1. Linear range
a. Linear correlation coefficient ∣r∣≥0.990
b. Linear range of GA is [0.20, 26.00] g/L; linear range of ALB is [10.00, 60.00] g/L.

2. Absorbance of blank
A (GA reagent) ≤ 0.20
A (ALB reagent) ≤ 0.40
3. Sensitivity
The difference of absorbance (ΔA) ≥ 0.04 while testing the specific GA sample of concentration of 9.31 g/L.
The difference of absorbance (ΔA) ≥ 0.10 while testing the specific ALB sample of concentration of 40.00 g/L.
4. Accuracy
ALB: relative deviation is within ±6%.
GA: check the accuracy using the following methods (in order of priority):
(a) Relative deviation is within ±15%.
(b) In contrast experiments, the absolute deviation is listed as followings:

5. Precision
GA: intra CV% ≤ 5.0%; inter CV% ≤ 10.0%.
ALB: intra CV% ≤ 2.0%; inter CV% ≤ 5.0%.
