Which LC column is recommended for fuel oils to determine dimer, trimer and tetramers , GPC analysis?
Hi Tee,
I discussed this with a GPC expert and we came out with an article that might help you: 1773 (researchgate.net)
In this article 3 columns with different pore sizes are coupled to get the necessary resolution over a broad MW range.
You can also use a set of PLgel 3 µm MIXED-E columns and here is an example for a polystyrene standard: 5990--7937EN_5989_5672.qxd (agilent.com). Keep in mind that you probably also need two or three columns in series to achieve a good resolution. You can find the part numbers of all these columns in the catalog above.
Regards,
Norbert
