- High-accuracy flow rate for high- speed analysis
The improved motor drive circuit expands the applicable range of flow rate accuracy of ±2% to an upper limit of 8.0 mL/min. This makes it possible to use the Chromolith TM column (manufactured by Merck) for ultra-high speed analyses at high flow rate. This pump is particularly suitable for analyses in the flow rate range of 0.5 to 8.0 mL/min.
- Enhancements in flow rate accuracy and retention
time reproducibility in gradient analyses
The innovative technologies used in the L-2100 pump (SMASH) are also incorporated in this pump for providing high accuracy in flow rate and retention time reproducibility.
- Degasser incorporated in pump unit
The degasser can be installed inside the pump module. This eliminates an extra space for installing the degasser, thereby enabling a compact system configuration. Furthermore, solvent substitution can be made efficiently by means of minimum piping reconnection.
