The AYE Combo from Testa Analytical is a unique GPC/SEC detector designed to have a high performance refractometer as an integral part of a viscometer, allowing both concentration and viscosity to be measured at exactly the same time on the very same sample segment.

As a consequence the AYE Combo Refractometer / Viscometer detector enables a much more accurate determination of molecular parameters and is particular suitable for applications focused on determining the structure and branching of complex polymers.

GPC/SEC is widely acknowledged as a primary analytical technique for characterizing polymers. The latest generation of complex high performance polymers however, add a notable degree of complication by requiring the use of “challenging” solvents such as DMSO, DMF and HFIP to dissolve them. Unfortunately, most GPC/SEC systems require frequent maintenance when operating with these solvents.

Drawing upon pressure transducers made out the most stable alloy available combined with highest grade 316T capillary tubing The AYE Combo detector is gaining rapid recognition as the GPC/SEC detector of choice for characterizing complex polymers in challenging solvents.

Size Exclusion ChromatographySize exclusion chromatography (SEC) is a liquid chromatographic technique used to separate and identify molecules based on their size, including polymers, proteins, nanoparticles & nucleic acid. SEC is further subdivided into gel filtration chromatography (GFC) and gel permeation chromatography (GPC) when an aqueous or organic mobile phase is used respectively. HPLC-based SEC systems and columns are available for analytical separation alongside SEC spin columns or filters to prep samples for many protocols.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
