A gel permeation chromatograph (GPC) is used to separate the components of a sample by size, this is known as size-exclusion chromatography (SEC).
GPC systems are widely used to analyze polymers and proteins in manufacturing, chemistry, and biology labs for quality control and analysis. GPC systems are composed of porous beads (the gel) inside a column, a pump to move the sample and eluent through the column, and a detector to detect when different analytes are eluted through the column. The detectors can be concentration sensitive or molecular weight sensitive.
Each gel permeation system has a range of sizes it can detect based on the pore sizes of the beads in the column, so before deciding on a system make sure you know the parameters you need. There are different types of porous beads that have varying affinities for materials and it is best for the gel to have a low affinity for the material you wish to analyze.

Excellent Reproducibility for Molecular Weight Distribution Analysis
The Nexera GPC System utilizes high-speed micro-plunger actuation and automatic pulse compensation to provide pulse-free solvent delivery and excellent elution time reproducibility.
Excellent Stability Maintained Even with Changes in Room Temperature
Nexera series detectors feature outstanding temperature-control functionality that provides superior baseline stability. Since differential refractive index detectors are particularly sensitive to room temperature fluctuations, the RID-20A detector features dual temperature-controlled optics to ensure superior baseline stability by minimizing the effects of temperature changes.
Identifying Unseparated Additives as Unique Peaks
If LabSolutions software is used with a PDA detector, then peak convolution functionality (i-PDeA II) based on MCR-ALS (multivariate curve resolution alternating least square) analysis can be used to qualitatively and quantitatively identify peaks that are not completely separated by the column. Peak deconvolution can also be used to confirm the purity of target peaks.
RID-20A Differential Refractive Index Detector
Designed for performance, the RID-20A differential refractive index detector is designed with a new reference cell auto-purge feature and validation support functions that dramatically improve GPC analysis productivity.
