PDF filler is VERY easy to use
PDF filler is VERY easy to use. The only sticky point for me sometimes is finding forms. There is a library connected to the app but I often find the forms there confusing. So I google them and import.

Great communication and customer service!
I haven’t used their service but I was being charged yearly by mistake for whatever weird reason, and they immediately gave me a refund and apologized. These guys are on the ball! Couldn’t complain if I tried.

What do you like best?
No more filling in forms with my handwriting.
What do you dislike?
Nothing really. I have found it be very helpful.
Recommendations to others considering the product:
Easy to use and affordable.
What problems are you solving with the product? What benefits have you realized?
A nice looking final document with legible information as opposed to my illegible handwriting. No need for a typewriter to fill in blanks on forms which means more space for other equipment.

What is the formula to calculate resolution?
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.
How do you calculate resolution in chromatography?
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.
What is the formula used to calculate resolution?
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.
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 increase resolution in column chromatography?
One of the simplest ways to improve resolution is to adjust solute B's retention factor. If all other terms in equation 12.19 remain constant, increasing KB improves resolution. As shown by the green curve in Figure 12.15, however, the improvement is greatest if the initial value of KB is small.
How do you calculate selectivity in chromatography?
It is generally calculated by k' = (tR — TM)/TM = tRy'/TM. g) The selectivity factor () of a column for two analytes (A eluting before B) is given by = KB/A = k'(B)/k'(A) = tRy'(B)/tR'(A).
What is chromatographic 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 is a good resolution in chromatography?
Resolution Rs The most important thing in HPLC is to obtain the optimum resolution in the minimum time. A resolution value of 1.5 or greater between two peaks will ensure that the sample components are well (baseline) separated to a degree at which the area or height of each peak may be accurately measured.
