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.

Multiple Analytical Techniques For Carotenoid Analysis In Capsicum Cultivars
Carotenoids and their derivatives are versatile isoprenoids based on a C40 tetraterpenoid skeleton and play a vital role in plants and animals, but, due to their high variability in the chemical structures, isomerization, poor stability and lack of commercially available standards, their identi cation in real samples is a challenging task.

An Improvement in Preparative SFC Efficiency Utilizing Online SFE-SFC System as a “Solid Autosampler”
Preparative SFC is a groundbreaking separation and purification technology. It has a number of advantages in comparison to preparative LC including simplified posttreatment, shorter analysis times, and different separation selectivity. With preparative SFC, the injection of large sample volumes is often required in order to increase the recovered amount.
