Question

What would be the effect on a chromatographic peak of introducing the sample at too slow a rate

Short answer

The impact of introducing the sample slowly onto a chromatographic peak is band broadening.

Step-by-step solution

Step1. Given information

The effect of introducing the sample at slow rate on a chromatographic peak is to be stated.

Step2. Chromatography

A chromatogram is a visual representation of chemical separation. Chromatography is the process of dissolving a sample in a mobile phase. This phase is then made to pass through a stationary phase.

Step3. Effect of introducing the sample at slow rate on a chromatographic peak

Band broadening occurs when the sample is added at a very slow rate at the peak of the chromatograph. The phenomenon of band broadening has an impact on the quality of the analyte acquired during the separation.

When the thin bands are formed, the quality of the analyte is much increased.
