HPLC Systems

High-performance liquid chromatography (HPLC) systems are essential tools in analytical chemistry, offering precise separation, identification, and quantification of components within complex mixtures. These sophisticated instruments employ a combination of pumps, columns, detectors, and software to analyze samples in diverse fields. HPLC systems work by forcing a pressurized liquid solvent containing the sample mixture through a column packed with a stationary phase. The interaction of the sample components with both the mobile and stationary phases leads to separation based on properties like polarity, size, and charge. This separation allows for accurate detection and quantification, supporting workflows in pharmaceutical analysis, environmental monitoring, food safety testing, and more. Common applications leverage techniques like UV-Vis spectroscopy, mass spectrometry, and... + More

Common applications leverage techniques like UV-Vis spectroscopy, mass spectrometry, and fluorescence detection, enhancing the versatility of HPLC systems from manufacturers like Agilent, Thermo Fisher Scientific, Waters, and Shimadzu. Advanced HPLC systems empower researchers with features like automated sample injection, gradient elution, and sophisticated data analysis software for seamless operation and interpretation. Whether it's an Agilent 1260 Infinity II or a Waters Alliance e2695 system, the selection of an HPLC system depends on specific research needs. From method development to routine quality control, these instruments provide crucial analytical data across various scientific disciplines. HPLC plays a vital role in chromatographic analysis, contributing to advancements in research areas like drug discovery, proteomics, and metabolomics. The technique is also crucial in sample preparation and purification for subsequent analyses, demonstrating its broad applicability in modern laboratories. ALT carries a wide selection of pre-owned, refurbished HPLC systems. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished HPLC systems from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
