Shodex
About the product
Shodex columns are used in High Pressure Liquid Chromatography (HPLC) for the analysis of compounds in liquid samples. The HPLC columns are mainly packed with polymer-based particles and offer unique and alternative performance for all major separation techniques. The columns are used in research, universities, small and large analytical laboratories, quality control and routine analysis.

Application
The products help researchers in the pharmaceutical, food, synthetic materials industry, as well as the environmental, biotechnological and life sciences sector.
Analytes:
- Proteins, peptides, amino acids
- Nucleic acids
- Organic acids
- Saccharides
- Drugs, metabolites
- Chiral compounds
- Vitamins, hormones, neurotransmitters, lipids
- Anions and cations
- Polymers
Features
Usually, the polymer-based HPLC columns show several advantages:
- pH stability for polymer-based columns is mostly pH 2-13
- longer lifetime because the material itself shows strong chemical resistance
- very low or negligible bleeding which makes them appropriate for mass spectrometry (MS), light scattering (LS) and charged aerosol detectors
