Does what it says. The only thing it says it does that I cannot perform on my Macbook is the ability to shift+tab to the next fill-in section after filling in a previous section.

great I run a water and sewage restoration business and this had made it possible to do all my emails and bids in the field. This program has made me thousands of dollars. As a business owner with no computer traning and self taught to pick at a keyboard. I now can compete with the business who run 5 employees doing paperwork and emails. This allows me to do the work of 4.

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in ****** and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund.I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.

Using the app has been pretty easy so far
Using the app has been pretty straight forward and intuitive. Getting used to how to edit a PDF to get consistent results. Has been a big help. Users always want a free solution and I'm still testing the 30 day trial but maybe if you want the right solution it needs to be a paid solution.

How do you clean a guard column?
remove to frit of the guard column & sonicate whole guard column assembly in 5% H2SO4 for 15-20min then sonicate in 100% water to remove acid and then with 100% methanol. Pressure will definitely get reduce.
How do you clean a column?
Wash the column with the current mobile phase without buffer, salt or acid for 10-15 min. If the ratio of organic solvent and water is changed, salt may precipitate. Wash impurities in a column to achieve a stable baseline: Use a solvent with strong elation properties in which the sample dissolves well.
How do you clean the normal phase column?
In general, you clean a column by flushing with a solvent that is stronger than the mobile phase. In this case, that would be water (or a water/methanol mix). The catch is that if your separation depends on having an additive adsorbed to the silica surface, you could be looking at long reequilibration times.
How do you clean a c18 column?
In your case wash the column with 70% water. 15% methanol. 15% acetonitrile. Divert the column fluent to waste not to contaminate your detector(s). Wash the column slowly over to 100% methanol and wash for at least 15 minutes. Wash the column over to 100% acetonitrile and wash for at least 15 minutes.
How do you equilibrate a column?
After the column has been flushed, it is usually best to store the column in the flushing solvent (acetonitrile or methanol) until it is used again. To re-equilibrate to normal operating conditions, equilibrating with 1020 column volumes of mobile phase usually is sufficient.
How do you back flush a column in HPLC?
Reverse the direction. Attach the column fitting that is normally at the outlet to the tubing that is normally connected to the inlet. Select the appropriate wash solvent. Wash out contaminants. Reconnect the column in the normal direction.
What is a guard column?
A guard column is a protective column or cartridge installed between the injector and the analytical column. It serves to remove the impurities and suspended solids from reaching the analytical column. Typically, it has a length of about 2 cm and internal diameter of 4.6 mm.
Why Silica is used in HPLC column?
Generally, silica gel is filled in the high-performance liquid chromatography columns because of its particle size and porosity that helps in separation of components and silica gel is also an inert material that does not react with mobile phases. The material filled in the HPLC columns is known as a stationary phase.
