Pumps

High-performance liquid chromatography (HPLC), ultra-performance liquid chromatography (UPLC), and liquid chromatography-mass spectrometry (LC/MS) systems rely on precise and dependable pumps for solvent delivery and gradient formation. These pumps provide the driving force for mobile phase flow through the chromatographic column, ensuring consistent and accurate results. They operate by precisely metering and mixing solvents at high pressures, enabling the separation and analysis of complex mixtures in applications such as pharmaceutical development, environmental monitoring, and food safety testing. Advanced features, like those found in Agilent's 1260 Infinity II series or Thermo Fisher's Vanquish Horizon systems, allow for sophisticated gradient control, flow rate adjustments, and integration with autosamplers and detectors, enhancing overall system performance and facilitating various chromatographic... + More
