See for yourself by reading reviews on the most popular resources:
I was please to see that I could edit my spreadsheet. I would suggest that once a work or set of numbers are highlighted that the program automatically is able to identify the font and size of the writing. Otherwise I was very pleased.

I hate having to type in a verification code when I leave for a bit. I know it is fro security reasons, but I would really appreciate it if you did not make it type the code.

Excellent, easy to use and saves a lot of time
It has saved me time mainly and a lot of hassles in getting physical signatures.
I have signed and shared documents within minutes rather than signing/scanning or mailing.
If you want to save time and get your documents signed ASAP, PDFfiller is a must have software. You can use it anywhere as long as you're online and you can edit it too without any hassles. It's very affordable.

It's very easy to use. Also the customer service is exceptional. Very responsive to My questions. When I decided I didn't need it anymore, they processed my cancellation quickly and easily.

I was happy that I found my forms, but you should have said from the first that it was a trial, I do not remember being told that It would cost me, but that's ok, I filled out and printed 3 N-311 Hawaii forms, which printed 5 sheets, I will gladly pay for them, but I do not want to continue my subscription to pdfFiller. I don't think I will ever need it again, but I do thank you for being there when I needed you.

Very satisfying!!! It has been a very helpful tool to modify and to fill up forms related to my work. The only thing I regret is not have been subscribed earlier.

What is resolution factor in HPLC?
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 the formula for calculating 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.
What is the tailing factor?
Definition: Tailing factor The tailing factor is a measure of peak tailing. It is defined as the distance from the front slope of the peak to the back slope divided by twice the distance from the center line of the peak to the front slope, with all measurements made at 5% of the maximum peak height.
How do you calculate selectivity factor?
f) The retention factor (k) is the ratio of the amount of analyte in the stationary phase to the amount in the mobile phase. 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 selectivity factor?
The selectivity (or separation) factor () is the ability of the chromatographic system to 'chemically' distinguish between sample components. It is usually measured as a ratio of the retention (capacity) factors (k) of the two peaks in question and can be visualized as the distance between the spices of the two peaks.
What is capacity factor in HPLC?
The capacity factor (also called “capacity ratio”) is symbolized by k' (USP terminology) or k (IUPAC/ASTM terminology). It is a measure of the retention of a peak that is independent of column geometry or mobile phase flow rate. The capacity factor is calculated as: k' = (tR — t0)/t0.
What does the retention factor k describe?
The retention factor and the retention time can be used to describe the chromatographic behavior of a sample component in a column. The retention factor is a relative value (dimensionless). ... k = 1 means that the component spends just as much time in the stationary phase than in the mobile phase.
