It's been fine so far although this is my first experience with it. I would like to be able to reduce the font size but I can't find where to do this.

I would only add that when adding text to the editor, it can be moved without blocking the height. Sometimes the PDF blocks the location of the text and it is difficult to align it with the original text.

Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0.
In chromatography, resolution is a measure of the separation of two peaks of different retention time t in a chromatogram.
In principle, it's just what it sounds like: the amount of resolution between adjacent peaks at which the signals will drop to the baseline.
Resolution. The resolution of an elation is a quantitative measure of how well two elation peaks can be differentiated in a chromatographic separation. It is defined as the difference in retention times between the two peaks, divided by the combined widths of the elation peaks.
Resolution is calculated using the separation of two peaks in terms of their average peak width at the base (tR2 > tR1). In the case of two adjacent peaks, it may be assumed that the peak width at the base wb1 wb2, and thus, the width of the second peak may be substituted for the average value.
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
The width at half-height is determined by measuring the height of the peak crest above the baseline, dividing by two, and then measuring the span between the rising and falling sides of the peak where the signal crosses the half-height points.
