What is negative peak in hplc?
In HPLC, the negative peak refers to a trough or valley observed in the chromatogram where the signal intensity drops below the baseline. This can occur due to factors such as noise, interference, or improper column packing. Negative peaks can sometimes affect the accuracy and precision of peak integration and quantification in HPLC analysis.
How do you calculate concentration from peak area in HPLC analysis?
To calculate concentration from peak area in HPLC analysis, you can use the formula: Concentration Peak Area / (Slope x Injection Volume). The peak area is obtained from the chromatogram, the slope is the calibration curve slope, and the injection volume is the volume of the sample injected into the HPLC system.
How do you use resolution factor in HPLC?
The resolution factor in HPLC is used to quantify the degree of separation between two adjacent peaks on a chromatogram. It is calculated by dividing the difference in retention times of the two peaks by the sum of their peak widths. A higher resolution factor indicates better separation between the peaks.
What can one read in the HPLC Column?
