Can high-concentration and low-concentration samples be processed on the same chromatograph?
It should be possible, but it depends on your requirements for the accuracy of the results. We use the same chromatograph to analyze more than 99.5% and less than 0.5% of the same component. If the composition of your sample is relatively complex, the results may be affected and the results need to be corrected. Welcome to further discussion
Yes, but not recommended. If the chromatographic column system and detector can be properly configured, components with different concentrations and different responses can be analyzed on one chromatograph. This is how many online chromatograms are implemented.
3# qugd should have no effect on the chromatographic column. I am very worried about this problem.
Yes, samples with low concentrations can be calibrated with corresponding high and low concentration standards during data analysis.
Yes, but be careful to use up the drying column
It is best not to analyze samples with the same components, otherwise the measurement results will be affected by each other.
It is best not to do it on one chromatogram, because it will cause more trouble.
It depends on what is being tested! !
Yes, but high-concentration standards and low-concentration standards must be used for external standards.
Be careful not to use the same injector, and ensure that the inlet is not contaminated. It should be fine. If there are many chromatograms, it will be OK to use them separately to measure high and low concentration samples.
