Shodex is a globally active brand. Shodex HPLC columns are developed, manufactured, and sold by Resonac group companies. In 1965, we began working on the development of separation technology using our polymer synthesis technology as a foundation. It was to measure molecular weight of our company products. In 1974 we began selling the developed products with our brand name, Shodex. We have sales offices located in Japan, US, Germany, China, Korea, and Singapore.
The golden metal fish is the Shodex symbol. The origin behind the golden fish is that since high-performance liquid chromatography (HPLC) is an analytical technique that uses liquids, it was associated with a fish that lives in a water. The mechanical form of the fish symbolizes the Shodex products, which is supported by advanced technologies, are always swimming smoothly at the cutting edge of the era.
We, Shodex, are continuously working on developing various HPLC columns to meet our customers’ analytical needs. Among the various columns, polymer-based columns which we have strengths on, provide excellent chemical stability and following features. Using those features, we offer different types of polymer-based columns.
- (1)Modified functional groups are stable and this ensures reliable analysis for a long time.
- (2)Matrix elutes derived from the packing material is minimum which leads to low baseline noise and enables high-sensitive analysis.
- (3)A wide working pH range allows users to select various analytical conditions.
Shodex HPLC columns are available for following separation mode uses.
- Reversed phase chromatography
- Hydrophilic interaction chromatography (HILIC)
- Ligand exchange chromatography
- Ion exclusion chromatography
- Ion chromatography
- Size exclusion chromatography (SEC)
- Ion exchange chromatography
- Chiral separation
