Found it difficult to navigate through at first but after using it a few times I figured out what I needed to get done but I'm sure there are easier ways to do things in there....

When going from preview back to editable view all imputed info disappeared. Not sure why that happened but I selected cancel and all info reappeared.

How does Column length affect resolution?
Doubling column length increases resolution but only by a factor of 1.4. Short column lengths (30-50 mm) will give short run times and low back pressures and are ideal for gradient analyses. Longer columns (250-300 mm) will give greater resolution but with longer analysis times and at a greater cost.
How does Column length affect retention time?
Column length A longer column will produce longer retention times but better separation. Unfortunately, if a component has too long a transit time in the column, there can be a diffusive effect that causes the peak width to broaden.
How does Column length affect chromatography?
Efficiency is directly proportional to column length (Equation 3). Increasing column length will increase efficiency. Doubling column length increases resolution but only by a factor of 1.4. The separation of four paraben compounds detailed in Figure 5 demonstrates the effect of column length.
What affects retention time in chromatography?
The boiling temperature of a compound is often related to its polarity. The more polar a molecule the higher its boiling temperature and sol the less time it spends in the gas phase. When the polarity of the stationary phase and compound are similar, the retention time increases.
What does longer retention time mean?
So high boiling point means a long retention time. The solubility in the liquid phase. The more soluble a compound is in the liquid phase, the less time it will spend being carried along by the gas. High solubility in the liquid phase means a high retention time. The temperature of the column.
What is resolution in column chromatography?
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.
What does resolution mean in chromatography?
In chromatography, resolution is a measure of the separation of two peaks of different retention time t in a chromatogram.
How do you find the resolution of a column?
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.
