Here are some of the most common types of HPLC pumps based on flow rates:
Nano LC pumps
These pumps are designed for very low flow rates, typically around 1 µL/min or less. They are used for highly sensitive applications such as proteomics, metabolomics, and peptide mapping.
Micro LC pumps
These pumps are designed for flow rates in the range of several tens of µL/min. They are us ed for a wide range of applications, including pharmaceuticals, environmental testing, and food analysis.
Semi-micro LC pumps
These pumps are designed for flow rates in the range of several hundreds of µL/min. They are used for applications such as drug discovery, metabolite profiling, and natural product analysis.
Analytical pumps
These pumps are designed for flow rates in the range of several mL/min. They are used for routine analytical work, such as quality control testing in the pharmaceutical industry.
Preparative pumps
These pumps are designed for flow rates in the range of several tens of mL/min or more. They are used for preparative chromatography, which involves isolating and purifying large quantities of a specific compound or mixture.
