Malvern’s webinar to focus on chromatography

5 July 2009

Malvern Instrument is planning to host a series of webinar that will help thousands of researchers and beginners to understand the use of chromatography for characterizing various nanomaterials and synthetic and natural polymers. The main focus of webinar will be SEC (Size Exclusion Chromatography) / GPC (Gel Permeation Chromatography).

The series of webinar will start from 16^th July 2009 with a focus on basic understanding of the technique, however it will continue for the year. SEZ OR GPC is widely used for characterizing a number of polymer and proteins that are now being examined for suitable use in nanotechnology applications and therefore the series of lectures will not only be beneficial for beginners but experts can also take advantage of the offer as registration for the program is open for all and that too free of cost.

In GPC, columns are used for separating various polymers, nanomaterials or other mixtures . Different materials including nanomaterials get separated on the base of their size and elutes from the column. Detectors or a series of detectors are used to detect the eluted material and thus we get the exact concentration of the material in the mixture. Now a days many advance detectors such as light scattering, viscometer are being used for getting the detailed information of the mixture including precise molecular weight distribution as well as size of the nanomaterial.

In an advance GPC technique, we can get a number of informative data such as particle shape, chemical composition, zeta potential etc and therefore the information obtained on a particular nanomaterial can be very useful in deciding its application in actual field.
