*Method selection depends on which procedure (A or B) is implemented. Please refer to the procedure description on the instruction sheet of the test kit.
The various parameters can also be analyzed using individual methods using reagents from bulk materials. Self-prepared reagents and test kits from other suppliers can be measured with the below workflow.
Prepare a dilution series with a standard.
Measure a calibration curve.
Save your individual method.
Quantification measurements can be performed by two different types of result calculations:
The configuration of both ways is described in detail within this video.
In this video, you will learn how to set up a quantification method with your own calibration curve to quantify an analyte according to the Beer-Lambert law.
