JASCO is also the world leader in the field of Circular Dichroism Spectropolarimeters and Vibrational Circular Dichroism Spectrometers. With the introduction of HPLC in the mid-1970's JASCO's experience in highly sensitive and accurate optical systems led to the development of a series of chromatographic detection systems. Fixed and variable wavelength UV/Visible and Fluorescence detectors were introduced featuring excellent sensitivity and reliability in compact modules.

In order to offer complete HPLC systems JASCO developed a variety of novel solvent delivery systems as well as other accessories such as column ovens, autosamplers, and PC based control and analysis software. Today JASCO offers a wide variety of HPLC modules, accessories and analysis software. The new JASCO LC-4000 Liquid Chromatography series is designed to operate at pressures approaching 15,000 psi for either gradient or isocratic separations, providing researchers with a powerful tool when using the new generation of small particle columns. LC-4000 Series includes a versatile series of components offering unique flexibility to build systems for routine and specialised applications. LC-4000 features the widest choice of optical HPLC detector: UV, diode array, fluorescence, chemiluminescence, CD, chiral and refractive index detector. Finally JASCO’s modular Supercritical Fluid Chromatography and Supercritical Fluid Extraction platforms provide a low-cost, fast, green technology with reliable and worry-free performance for a wide variety of applications.
