I was asking them for a refund as I don’t need the subscription to get through as I am on maternity leave which means I will no longer use it. Bruce through online support helped me smoothly.

Was OK after had a chat. I plan on keeping PDF filler after the trial period ends for 1 year so I can do my 2024 taxes done before the renewal date. If you have or willing to have a 3 month subscription from February to April I would be interested.

This has been a very pleasant surprise as I am a avid &somewhat devoted Adobe Acrobat user &didn't think that there existed any other app that could even come anyway close in performance, features &value to what has long been the industry standard for me...They created PDF file format..but PDFfiller has made working with them much more user-friendly &intuitive. Using the two in tandem has been both very eye-Opening ,&productive!!!

awesome online support
Online support with Kara was awesome! I had an answer to file encryption in minutes and was able to continue working without interruption.
PDF filler platform and support is great!

What do you like best?
I enjoy the ability to amend docs without having to print.
What do you dislike?
There are many buttons to navigate, perhaps a simpler layout
What problems are you solving with the product? What benefits have you realized?
I complete many Acord insurance applications on PDF. Benefits are submitting clean looking professional apps.

I used this product to edit and fill out an application and found the software to be very easy to use and very effective!
I unfortunately forgot to cancel my 30day free trial and was unexpectedly hit with the charge the week before payday when I really couldn’t afford it.
I explained my situation to the customer support team via chat and they happily refunded me my payment!
Could not be happier with the service they provided and the understanding of my situation.
Would definitely recommend!

What is column resolution?
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.
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.
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.
What is resolution formula?
Resolution (r) = 1.22/(NA(obj) + NA(cold)) Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, is the imaging wavelength, NA(obj) equals the objective numerical aperture, and NA(cold) is the condenser numerical aperture.
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 find the resolution of a microscope?
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. D= /2 NA. Where is the wavelength of light used to image a specimen. D= 2 /NA2 R= 1.22 /Naomi+Second.
