AUTOSAMPLER FOR SFC AS-2059-SF Autosampler
When using supercritical carbon dioxide as a mobile phase, it replaces the content of the sample loop with supercritical carbon dioxide with each injection. Continuous introductions of samples requires the aspiration of the next sample after safely discharging the carbon dioxide in the sample loop and fully replacing it with an organic solvent. The AS-2059-SF can safely discharge carbon dioxide in the sample loop and continuously inject samples. The injection method can be selected as either a fixed injection volume that fills the entire sample loop or a variable injection volume that introduces the sample in a portion of the sample loop. The variable injection volume method is also capable of full injection with zero sample loss. Temperature Control
The optional sample-warming unit (TC-2059) can control the temperature of a sample between 4ºC and 60ºC in 1ºC increments (temperature control precision: ±1ºC).
Supercritical Fluid Component
Supercritical fluid systems require a pump for transferring liquid carbon dioxide.
Whichever SFC system you choose, from analytical to semi-prep to prep scale, we have an SFC fraction collection system to match your needs.
Supercritical fluid systems that use carbon dioxide add a modifier solvent when boosting the degree of extraction freedom.
Density changes due to changes in temperature have a major impact on the separation and extraction process on supercritical fluid systems.
Evaluating optical characteristics under a supercritical state requires a detector and a high-pressure resistant cell
JASCO offers the BP-2080, which is capable of automatic pressure control, and the BP-2080-M, which is capable of manual pressure control.
Achieving extractions and chromatograms with high reproducibility on a supercritical fluid system requires stable temperature control.
JASCO offers a variety of valves available for system upgrades, including automatic valves for channel switching and distributing, stop valves for cutting off channels, etc.
