The characteristics of supercritical fluid vary greatly due to changes in pressure. Achieving extraction and chromatograms with high reproducibility on a supercritical fluid system requires a device that can perform pressure control in a stable manner. JASCO has solved the problem by developing a pressure regulating system which operates on different principals from conventional regulators. JASCO offers the BP-2080, which is capable of automatic pressure control, and the BP-2080-M, which is capable of manual pressure control. Select a pressure control valve suited to the intended purpose of your SFC/SFE system.

Supercritical fluid systems require a pump for transferring liquid carbon dioxide. JASCO offers the PU-2080-CO2 for analysis applications, the PU-2086-CO2 for applications ranging from analysis to preparative isolation, and the PU-2088-CO2 for high-volume preparative isolation. Select a pump suited to the desired application.

Use this supercritical fluid autosampler to measure multiple-specimen samples by means of SFC. This unit is for continuously injecting samples. This unit introduces a sample into the sample loop and then injects it into supercritical carbon dioxide by switching an injection valve. 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 introduction 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 fixed injection volume that fills the entire sample loop or 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.

Evaluating optical characteristics under a supercritical state requires a detector and a high-pressure resistant cell. The monitoring of samples in supercritical fluid is possible by replacing the flow cell section in one of JASCO’s liquid chromatography detectors with a high-pressure resistant cell. Select a detector suited to the intended purpose of your SFC/SFE system including:

	UV-2070/2075 UV/Vis Detector
	MD-2010/2015 Diode Array Detector
	CD-2095 Circular Dichroism Chiral Detector
