Instruments and detectors optimized for GPC/SEC

Instruments and detectors optimized for GPC/SEC.

Gel Permeation Chromatography is a powerful technique for determination of fundamental parameters of synthetic and natural polymers ranging from Molecular Weight right through to structural information about branched macromolecules. Unlike many other suppliers, our equipment is specifically designed for polymer characterization and is therefore optimized to operate with all solvents used in GPC/SEC. This includes even the most challenging solvents such as DMF, HFIP, DMAc and DMSO as well as more common solvents like THF and aqueous buffers. Our GPC/SEC range includes top performance MALS and Viscometer detectors and a unique Refractive Index / Viscometer combination detector which sets a new performance benchmark for structural investigation of complex polymers.

Pump problems with gas bubbles.

Pump problems with gas bubbles.

Many thanks to the editorial team at LaborPraxis for recently publishing our article – ‘Danger recognized, Danger averted.’ The enemy of peristaltic pumps are gas bubbles. In this German language article, you will find out what influence dissolved and undissolved gas has on the performance of these pumps and thus on HPLC, uHPLC and GPC/SEC systems and what can be done about it.
