Dec. 27th, 2019

In the daily HPLC analysis work, it is sometimes found that there are significant differences in experimental data. In this case, the experimenter can generally analyze the reasons from the following aspects. It will give the relevant solutions in this article, hoping to help you solve the problems at work.

Reason1:Insufficient Sample Volume

Answer：Increase sample volume

Reason2:Sample does not flow out of the chromatography column

Answer：Change swelling phases or chromatography columns, depending on the chemical properties of the sample

Reason3:Sample does not match detector

Answer: Adjust the wavelength or change the detector according to the chemical properties of the sample

Reason4:Detector decay too much

Answer：Adjust the attenuation

Reason5:Detector time constant is too large

Answer： Reduced time parameter

Reason6:The flow phase flow is not suitable

Answer：Adjust the flow rate of sample

There's another reason, which impact on experimental data. The quality of chromatography vial. When you purchase chromatography vial, Please choose the formal manufacturers of chromatography vial.
