How to create a calibration curve for different concentration fractions in Agilent liquid chromatography?
Thread Content
How can score data at different concentration levels be combined to form a calibration curve? The general procedure involves preparing samples at different concentration levels, then analyzing them according to the calibration levels to automatically generate a calibration curve. This process is slow, and if a calibration peak is not detected due to retention time shifts, the entire process must be repeated. To save time, given the previously collected score data at different concentrations, how can a calibration curve be created? Using data for comparison is much simpler than redoing the sampling and calibration analysis, and it also makes it easy to modify the data!
I’m not quite sure how you need to create multiple calibration curves.
This cannot be done; updating the calibration curve is intended to eliminate factors such as sample processing and instrument conditions. Mixing old data with current data will not achieve this goal. Each standard sample can be injected several times, and the best spectrum can be selected to create a calibration curve; alternatively, the peak detection time can be adjusted to address issues with incorrect peak identification.
