PoroCheck FAQs
What exactly do I need to use PoroCheck Software for pore size analysis ?
Just three things: PSS PoroCheck software, HPLC instrument, size or molar mass standard. The retention of the standards are copied from the LC system to the PoroCheck software for data analysis. Any type of porous material (even coarsely grinded) which can be packed into any column. Either use your own or order the complete PSS Pore Size Analysis Kit.
I am new to pore size investigations. How do I start ?
If you are new to the field, purchase the PSS PoroCheck starter kits (available for organic or aqueous solutions). It contains the software, the reference standards, a column which will hold the porous material and a starter booklet introducing the method and a step-by-step guide to obtain results without head-aches.
I have the PoroCheck trial software. How can I upgrade ?
Very simple. Just send in a purchase order (by mail, fax, e-mail) and we will deliver the complete package by mail, fax or e-mail. E-mail delivery is instantaneous after credit card check.
How can I update older versions of PoroCheck ?
Software updates are free within 12 months after initial purchase. Users will be informed automatically about a newer version. After 12 month, inexpensive update offers are available from PSS to ensure users use the best system for their investigations.
PoroCheck is very important for our work. Can we obtain a multi-user version ?
Multi-user versions for departments and institutes are available at very reasonable prices. Please ask for a quotation, mentioning the maximum number of users in your department or institute.
Which types of samples can I investigate with PSS PoroCheck ?
Any type of porous material. It will be more difficult to pack porous fibers, plane membranes etc into a column for chromatographic investigation, but it can be done. Membrane investigations can also be done (and sometimes better) by filtration SEC studies. One of the important advantages of chromatographic porosimetry is that it will not impose any forces (vacuum, high pressure) on the samples. Even fragile materials and soft matter can be investigated, which is not possible by any other method without structural damage.
