check The chromatogram below was recorded. What could be done to improve the appearance of this chromatogram?


Answer

Video. Separating peaks by changing the chart speed.

The peaks in the chromatogram are too close together. If the peaks are too close together or too spread out, adjust the tracking speed. A higher setting will cause the paper to scroll through the recorder faster, causing the peaks to be farther apart (but the peaks will be broader).
