High Performance Liquid Chromatograph Chromaster PLUS
The Chromaster® PLUS is engineered to meet the evolving needs of modern laboratories, bridging the gap between conventional HPLC and high-resolution UHPLC. Built on three core pillars—Performance, Functionality, and Reliability—this system offers an "HPLC for today and tomorrow". Whether you are performing routine analysis or pushing the boundaries of high-speed, high-resolution research, the Chromaster® PLUS provides the robust stability and ease of use required for consistent, world-class results.
Overview
-
Entry-Level UHPLC Capability (60 MPa)
The system supports a pressure range up to 60 MPa, making it compatible with both conventional 40 MPa methods and advanced columns containing $2.0μm or smaller particles. This allows for improved resolution and significantly shorter analysis times.
-
Unparalleled Retention Time Reproducibility
Featuring Hitachi’s unique high-speed feedback real-time control and High Frequency Mode (HFM), the 5110/5160 pumps ensure extremely accurate solvent delivery for highly reliable results.
-
Extremely Low Carry-over (≤ 0.003% )
Thoughtful engineering of tube connections and injection port shapes eliminates dead volume, ensuring minimal carry-over for even the most persistent components7. The 5260 model further enhances this with a built-in two-solvent washing function.
-
Versatile Column Management
The system offers generous column compartments, with the 5310 Oven easily accommodating up to three 300 mm analytical columns9. It includes a block-type Peltier pre-heating function to deliver excellent peak symmetry and shape.
-
Innovative "Tool-less" Usability
Designed for maximum convenience, the system features a unique MEM column fitting that can be secured by finger-tightening while maintaining pressure tolerance up to 140 MPa.
-
Space-Saving Safety Features
A built-in 3-liter waste tank is housed directly within the column oven, freeing up laboratory floor space and improving overall operational safety.
