EXTREMA is a high-performance liquid chromatograph (HPLC) that brings together the best of JASCO’s technology. You can build the optimal system for your purpose from a variety of units, including UHPLC, RHPLC (Rapid Separation HPLC), semi-preparative pumps, and high-sensitivity detectors. The chromatography data system, ChromNAV, renowned for its operability and processing functions, now offers enhanced functionality and user-friendliness with its upgrade to Ver. 2.0. This version includes various improvements, making it more efficient and intuitive for users.
System lineup
There are three types in the lineup: HPLC/RHPLC, UHPLC, and Prep-HPLC. Many units are available, and you can build the optimal system by combining units suited to your purpose.
UHPLC
Ultra High Performance Liquid Chromatography (UHPLC) uses columns packed with ultrafine particles of 2µm or less, enabling separation at high pressure (up to 130 MPa). This method allows for high-speed separation while maintaining high separation efficiency. Compared to conventional HPLC, UHPLC significantly shortens analysis time, reducing it to just 1/5 to 1/10 of the usual duration. Additionally, it minimizes the amount of mobile phase solvent used, cutting it down to nearly 1/10, thus enhancing both efficiency and sustainability.
HPLC/RHPLC
Rapid Separation HPLC (RHPLC) provides a high-speed analysis method that spans the range from conventional HPLC to some UHPLC applications. This analytical system utilizes fully porous packed columns with particle sizes of 2 to 3 µm and core-shell columns. Moreover, it supports measurements in the medium pressure range (30 to 70 MPa), positioning itself as the future standard analytical method.
Prep-HPLC
Preparative High Performance Liquid Chromatography (Prep-HPLC) focuses on isolating and purifying target compounds with high purity from synthetic products and natural substances. EXTREMA, equipped with a semi-preparative pump, enables its use as a semi-preparative high performance liquid chromatograph (Prep-HPLC). Additionally, it facilitates micro- and ultra-micro-preparative separations when integrated with an RHPLC or UHPLC system.
Unit Lineup
One can construct a system by combining a wide range of units according to the intended purpose, allowing for flexibility and customization.

Hardware
AS-4050/4050i for HPLC
The basic model AS-4050/4050i serves as the best model for conventional HPLC, holding up to 60 samples. Users can opt for sample cooling. The AS-4050i, an inert type, uses no metal materials in the flow paths that contact the sample solution or mobile phase.
AS-4150 for RHPLC, AS-4250 for UHPLC
The high performance models, AS-4150 and AS-4250, offer advanced capabilities. The AS-4150, with a maximum pressure resistance of 70 MPa and a shortest injection time of 30 seconds, suits RHPLC applications. It also supports sample dilution and pre-column operations. The AS-4250, designed for UHPLC, features a maximum pressure resistance of 130 MPa, making it ideal for high-pressure applications.
For preparative use AS-4058
The large volume injection model AS-4058 can inject up to 10mL (standard is 5mL). It is used in combination with semi-preparative pumps such as PU-4087.
