What a Quaternary Pump HPLC System Can Do: One Instrument, From Routine QC to Impurity Analysis and Dissolution Testing
Share
Method development staff run into the same practical problem constantly: different tests require very different mobile-phase ratios, and re-preparing mobile phases every time a method changes is inefficient. That's exactly the problem quaternary pump design is built to solve.
Quaternary Pump vs. a Standard Dual Pump
A standard dual-pump system typically handles a mixing ratio between only two mobile phases. A quaternary pump can deliver four mobile phases simultaneously, with the four channels combinable in any proportion — covering a much wider range of method-development scenarios without needing to re-blend a premixed mobile phase for every new method.
The EasySep-5010 HPLC System's quaternary pump design comes standard with a built-in four-channel online degasser that automatically degasses in-line to avoid bubbles from mixed mobile phases; it also has an in-line automatic plunger-cleaning function, with configurable cleaning programs for automated in-line cleaning that reduces manual intervention.
From Routine QC to Complex Method Development: What One Instrument Can Cover
The value of a modular design is flexibility — the same hardware, by swapping detector combinations and adjusting mobile-phase ratios, can cover a wide range of very different test types:
- Content and uniformity assay: the foundation of routine QC release testing
- Related-substances and impurity-profile analysis: demands higher resolution and detection sensitivity, often requiring gradient elution paired with a DAD detector's simultaneous multi-wavelength detection
- Dissolution testing: needs stable, reproducible mobile-phase delivery and precise column-temperature control
- Food and environmental contaminant screening, biochemical and natural-product analysis: applications extending beyond pharma, to labs with a broader range of test targets
For a lab, this means not having to configure a separate dedicated instrument for every category of testing — a single modular platform can flex its configuration as testing needs change.
Three Column-Oven Control Modes
Method development frequently requires adjusting column-temperature strategy for different samples. The EasySep-5010's column thermostat is software-controlled with real-time temperature display, and can hold multiple columns simultaneously with software-configured automatic switching for easy operation, with a wide temperature range and fast heating for higher efficiency.
Frequently Asked Questions
Q: Can the EasySep-5010's four quaternary-pump channels be combined freely?
