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.

Custom detectors for liquid chromatography.

Drawing on decades of experience, we have created an expanding range of high-performance HPLC, uHPLC and GPC/SEC detectors, pumps, accessories, and software products that can be customized to meet the exact needs of liquid chromatography manufacturers. Our team of knowledgeable technical and engineering staff, based here in Germany, are available to discuss your OEM needs and to provide seamless integration of our technology into your existing or new product.

Informative introduction to Liquid Chromatography flow monitoring.

A new online presentation compares and contrasts the shortfalls of conventional flow monitoring technologies with the proven advantages of our AB4000X series Liquid Chromatography flowmeter. Details of how this sensitive real-time device can be used to determine just how constant flow from your HPLC or GPC/SEC pump really is are provided. Further information is included on other liquid chromatography applications benefiting from this affordable, easy-to-use device.

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.
