GPC Systems

A GPC system, or Gel Permeation Chromatography system, is used to analyze the molecular weight distribution of polymers and macromolecules. It helps researchers and manufacturers understand the size and structure of molecules, which is essential for various applications such as material development and quality control.

GPC systems are primarily used to analyze polymers, biopolymers, and other macromolecules, such as proteins, polysaccharides, and synthetic polymers. They are ideal for assessing the molecular weight and distribution of these materials.

A GPC system separates molecules based on their size by passing them through a column filled with porous particles. Larger molecules are eluted first, while smaller molecules are retained longer, allowing for the determination of molecular weight distribution.

A GPC system provides data on the molecular weight distribution of your sample, including parameters like the weight average molecular weight (Mw), number average molecular weight (Mn), and polydispersity index (PDI), which describes the spread of molecular weights within the sample.

GPC systems are widely used in industries like polymers, pharmaceuticals, biotechnology, and environmental testing. They are crucial for product development, quality control, and research in fields such as material science, drug development, and packaging.

Yes, while GPC systems are designed to be user-friendly, they do require some level of technical knowledge. Users typically need to be familiar with chromatography principles and the interpretation of molecular weight distribution data. Training from the manufacturer or supplier is recommended to ensure optimal use.

New GPC systems are brand-new, with the latest technology and full manufacturer support. Refurbished systems are pre-owned, but have been restored to factory standards, offering a cost-effective solution without compromising on performance. Both types can be highly accurate, but refurbished systems may come at a lower price.

When choosing a GPC system, consider factors like the required analysis range (e.g., molecular weight), type of sample you will be analyzing, available space in your lab, and budget. It’s also important to select a system that is compatible with the specific detectors and software you need.

Yes, GPC systems are versatile and can be used in both research and industrial settings. In research, they are used for developing new materials and understanding molecular properties, while in industry, they are used for quality control and production monitoring of polymers and other macromolecular products.

Throughput can vary depending on the system and the sample type, but generally, GPC systems can process multiple samples per day. The analysis time for a single sample typically ranges from 30 minutes to 2 hours, depending on the complexity of the sample and the desired level of analysis.
