1. Build standard curve
To use several configured standard samples, input the concentration of sample standard, collect the absorbance of
standard sample, through the relationship between concentration and absorbance is calculated curve parameters,
use this parameter to measure the concentration of the sample.
1)
Curve fitting mode: there are first order fitting, first order fitting through zero, and second order fitting.
2)
Curve building method: there are standard sample method and coefficient method. Stand sample method is to
prepare sample first , build curve, and then test sample. Coefficient method is to enter the known coefficient and
build standard curve, then to test sample.
3) the number of samples: at least 2 samples. More sample numbers, more accurate testing data.
4) concentration units: Enter the concentration value of each standard sample, because the parameters of the
curve has established limits, please select the appropriate concentration units.
5) wavelength value is required.
