A friend asked this question "How to calculate the calibration factor of ABB2000 chromatograph"
Chromatographic quantitative analysis is based on the fact that the measured component quantity is proportional to the detector's response signal (peak area or peak height). However, the same substance often has different response sensitivities on different types of detectors; likewise, different substances are in the same test. The response sensitivity on the device is also often different, that is, the same amount of different substances produce different values ​​of peak area or peak height. Thus, the relative percentage of peak area or peak height of each component is not equal to the percentage of each component in the sample. Therefore, a quantitative correction factor is introduced, and the corrected peak area or peak height can quantitatively represent the amount of the substance.
(1) Definition of quantitative correction factor
The quantitative correction factor is divided into an absolute quantitative correction factor. From the relationship between the above peak area and the mass of the material W = fA, we know that: f = W / A
f is called the absolute quantitative correction factor, which is the mass of the material represented by the unit peak area. This is the quantitative correction factor expressed by the peak area, and the peak height can also be used to represent the quantitative correction factor.
In addition, they are also expressed by their reciprocal, referred to as the response value.
Response factor = sample concentration / peak area
