Sugar column
|
The analysis of general sugars can adopt separation modes such as coordination exchange, volume exclusion, ion exclusion, and normal phase.SUGAR |
series Sugar separation combines different separation modes, such as coordination exchange, volume exclusion, ion exclusion, and positive phase. |
|
Suitable for separating sugars and sugar alcohols.Asahipak NH2P |

|
Using the normal phase mode to achieve sugar separation is suitable for separating monosaccharides, oligosaccharides, and sugar alcohols.SUGAR KS |
series |
|
Combining volume exclusion and coordination exchange modes to achieve carbohydrate separation. The exclusion limits of each column are different, so the appropriate column can be selected based on the molecular weight of monosaccharides, disaccharides, oligosaccharides, and polysaccharides. |

Ion chromatography column
|
Ion chromatography is divided into two methods: with suppressors and without suppressors. Shodex columns for analyzing anions and cations are available for both inhibitory and non inhibitory systems. We also provide columns for practical post column derivatization analysis of transition metal ions and rare earth metal ions. Please select the column based on the analysis requirements and ion types. |

Polymer carrier normal phase and reverse phase chromatography column
Shodex's polymer carrier chromatography column has a longer lifespan and a wider pH range compared to silica carrier chromatography columns.
Organic acid specific column
Generally, organic acid analysis can be achieved through ion exclusion, ion exchange, and reverse phase modes. The Shodex organic acid specific column RSpak KC-811 introduces ion exclusion, volume exclusion, and reverse phase composite modes to achieve the separation of multiple organic acids. When using KC-811, KC-G is generally used as a protective column for samples, and KC-LG is recommended for samples with high impurities.
Shodex chiral column
The Shodex ORpak and Shodex AFpak ABA-894 series produced by Shodex use fillers with coordination groups, which can identify various optical isomers. There are three types of coordination groups: α, β, and γ cyclodextrin derivatives (CD), L-amino acid derivatives, and bovine serum albumin.
