Question
I am writing to inquiry if your “”OH pak sb-806M HQ” size exclude column have the capacity to separate the povidone mixtures, which may contains PVP K-30, PVP K-90 and PVP K120. If you have any related data about it would be helpful,
We are going to buy one OH pak SB-806M HQ.

Povidone mixtures Molecular weight range as below:

PVP-K30
44,000—————–54,000
PVP-K60
320,000—————380,000
PVP-K90
1,000,000———–1,500,000
PVP-K120
1,600,000———–2,000,000

Answer
We have following application for the povidone analysis.
http://shodex.net/index.php?seitenid=1&applic=1481
It shows separation of two povidone (probably similar to K30 and K60).
More detailed information is included in the attached poster we presented at Pittcon last year.

However unfortunately, I do not think that size exclusion mode can separate K90 and K120, since their MWs (largest of K90 and smallest of K120) are very similar.
