My life has gotten so much easier since I purchased this program. My paperwork is legible and so neat when filling forms that do not have enough space.

I was able to upload and edit a document. I sent it to someone across the country who printed, signed it and sent it back. I then e-signed it and submitted it to a third party successfully.

What do you like best?
No more printing and filling out forms by hand.
What do you dislike?
I used to be able to upload a signature from an iPhone photo, and it could be placed on a document in a way that it look like it was written there, and not a pasted photo. I liked this and cannot seem to do this anymore.
What problems are you solving with the product? What benefits have you realized?
It's amazing how many forms still need to be filled out by hand in this age of tech and no typewriters. Printing documents, hand writing, then rescanning to a recipient is messy, time consuming and wastes ink and paper. Besides, make a mistake, and you need to start over with a new form. And don't get me started with "white out." PDFiller streamlines all this and results in a very neat, professional looking document. I do lots of contracts, and don't always get red-line drafts to work with. I can use PDFiller do do red-lining (word-processing changes to early drafts) and send them right back to the counter-parts. Then with the final draft the PDFiller signature feature allows me to initial or sign, and send - again without printing/rescanning. Since for many transactions e-transmitted signatures, as opposed to "wet" signatures, has become standard and legally acceptable the process is now a breeze. And if I still have to go back for further revisions the prior versions are all saved in PDFiller.

I signed up for the $1 trial but did not want the 1 year subscription -- refunded in two days! I signed up for the $1 trial but did not use it for whatever reason. I have adobe DCF but used PDF filler one time to check it out or whatever. In any case, one month later I get hit with the $102.10 one year subscription charge I didn't see coming. I call expecting to be on hold for two hours.. but .. no... about a few minutes on hold and they refunded the whole thing.. refund hit in two days. So, I believe they should be applauded for that. I'm sure some people love it and go for the subscription. But it's really nice to know they're actually honest and refund the money if you ask.

I canceled my trial but maybe I didn't… I canceled my trial but maybe I didn't complete it on my end. Either way the subscription was charged to my card and I contacted support which usually is a nightmare when you have billing problems and it was honestly quick and painless. Great service and they got my refund and account canceled quickly. Thank you to Alice from support

Great services with an excellent customer care policy I enjoyed great services provided by pdfFiller through an annual plan. I used their service in all my dealings with pdf documents. Then for professional reasons, I had to cancel my subscription, and pdfFiller team was extremely kind in offering me a full refund of my subscription fee. Just after 3 minutes of sending them a message, they responded back explaining the details of my refund process. That is what I call a great customer care and professionalism! Once again thanks a lot!

Mass transfer improves dramatically as the particle size is decreased due to its relationship to the square of the particle size [dp2]. For smaller particles, it takes less time for an analyte molecule to travel into the pores, interact with the chromatographic surface, and be swept back into the mobile phase.
Particle size particularly affects the efficiency term of the fundamental/Parnell resolution equation (Equation 2). Efficiency is inversely proportional to particle size (Equation 3); hence, a decrease in particle size will result in an increase in efficiency.
Mass transfer improves dramatically as the particle size is decreased due to its relationship to the square of the particle size [dp2]. For smaller particles, it takes less time for an analyte molecule to travel into the pores, interact with the chromatographic surface, and be swept back into the mobile phase.
The surface area of the particle is inversely proportional to the pore diameter and therefore a 3 mm particle with a 120 nm pore diameter will have more than twice the surface area of a 3 µm particle with a 300 nm pore diameter.
The smaller particle size has a broader optimum flow rate range at much higher flows than larger particle sizes. Some key benefits for decreasing particle size include: Increased column efficiency As shown in equation 1, efficiency is inversely proportional to particle size.
Why does the van Demeter curve shift downward as the particle size decreases? ... The pressure required to push solvent through the column increases as the particle size decreases. Higher pressures mean the analyte spends less time in the column which reduces the contribution of the B term to the plate height.
Maximizing Sensitivity can be increased by reducing column length, reducing internal diameter, and increasing efficiency (i.e. smaller particle size, minimize extra system/column volume, increase flow rate etc.).
Step 1: Reduce Column Length Simply shortening the HPLC column reduces separation time; however, resolution will also be reduced due to a decrease in the plate number (available stationary phase surface). In general column length is directly proportional to retention time, column efficiency, and back pressure.
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.
In summary, the pore size of a column is selected so that the sample molecules have easy access to the pores. Smaller-pore columns are desired because of their higher surface area, as long as the analytes are sufficiently small to easily enter the pores. The particle size controls column efficiency or plate number.
