Analysis of Polystyrene Standard
Shim-pack GPC Series
HPLC Column
Shim-pack GPC series columns are used for the determination of tetrahydrofuran (800 Series) and dimethylformamide (800D series).
Please exchange the shipping solvent when you use other solvents for your analysis. (Click here for more information.)
The technique of GPC does not utilize such chemical reactions as partition, adsorption, and ion exchange, but a physical reaction consisting of a separation based on molecular size of the sample components. Therefore, this method is suitable for the measurement of molecular weight distribution of high polymers and oligomers.
Shim-pack GPC series are packed with polystyrene polymers with respective degrees of cross-linking in order to meet exact analysis requirements, ranging from analysis of high polymers to that of oligomers. GPC-80M and GPC-80MD are mixed gel columns.

Biodegradable Plastics
In order to reduce plastic waste, the development of eco-friendly alternative materials is being promoted. As an alternative, biomass plastics and biodegradable plastics are becoming more widely available. Biodegradable Plastics are plastics that are decomposed into low-molecular compounds by microorganisms in the environment. So they break down easily in nature, which is an opposite characteristic of petroleum-based plastics.

Shimadzu has released the Nexera lite inert
Nexera lite inert is a robust HPLC system that eliminates the risk of corrosion by high-salt mobile phases and sample adsorption onto metal surfaces. It improves the data quality of protein analysis in biological samples with superior reproducibility, without any special considerations for stable and long-term use.
