Chromatography (HPLC-GPC)

High-performance liquid chromatography (HPLC) is a technique used to separate compounds dissolved in a liquid sample and allows qualitative and quantitative analysis of what components and how much of each component are contained in the sample.

It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column.

Shimadzu DGU-20A5R HPLC Degassing Unit

Removing dissolved gases in mobile phases is an important step for ensuring proper function of pump check valves, and to prevent outgassing in the detector flow cell. The degassing units feature extremely efficient degassing in a low-volume, compact design. Each degassing unit can be powered by a LC-20A or LC-30A series pump, and the pump control panel can display the degassing unit vacuum level.

Shimadzu RID-20A Refractive Index Detector

Inheriting the stability and extensibility that are the strengths of the Prominence series, the new RID-20A model of differential refractive index detector is designed with a new reference-cell auto-purge feature and validation support function.

Shimadzu CTA-20A Prominence HPLC Column Ovens

Large-capacity, forced hot-air circulation units, the CTO-20A HPLC column ovens precisely regulate the temperature around the column. Automatic fan-speed control varies with the set temperature to provide stable analysis that is not influenced by the ambient temperature.

Shimadzu LC-20AD Parallel Double Micro Plunger Type

The LC-20AD offers the most stable solvent delivery performance in the world. With an automatic pulsation-correction mechanism and high-speed micro plunger drive, it achieves pulse-free solvent delivery. Improvements in solvent-delivery control firmware have significantly improved performance in the micro-flow-rate range below 50 µL/min

Shimadzu SIL-20A HT Autosampler

A total-volume injection type autosampler, the SIL-20A enables high-speed injection and high-throughput sample processing without wasting sample. It is designed to ensure greater stability, with improved durability attained through modifications in valves and sample loops. Multiple vial and plate types are supported, and a control vial rack isolates standards from analytical samples.
