Detectors

High-performance liquid chromatography (HPLC), ultra-performance liquid chromatography (UPLC), and liquid chromatography-mass spectrometry (LC/MS) systems rely on sophisticated detectors to analyze separated compounds. These detectors employ various principles, including UV-Vis absorbance, fluorescence, refractive index, and mass spectrometry, to quantify and identify analytes in complex mixtures. The detector's role is crucial in providing sensitive and selective detection, converting the separated components into measurable signals. They support workflows involving sample preparation, chromatographic separation, and data analysis for applications such as pharmaceutical development, environmental monitoring, food safety, and proteomics research. Precise and reliable detection from manufacturers like Agilent, Waters, and Thermo Fisher Scientific ensures accurate results in these critical applications. Different detector types cater to specific analytical needs. For... + More

Precise and reliable detection from manufacturers like Agilent, Waters, and Thermo Fisher Scientific ensures accurate results in these critical applications. Different detector types cater to specific analytical needs. For instance, UV-Vis detectors are commonly used for analyzing compounds with chromophores, while fluorescence detectors offer enhanced sensitivity for fluorescent molecules. Mass spectrometry detectors, often coupled with LC systems (LC/MS), provide detailed structural information and enable precise identification of compounds, even in complex matrices. Selecting the appropriate detector, considering factors such as sensitivity, selectivity, and compatibility with the chosen chromatography technique, is crucial for successful analysis. Researchers rely on brands like Sciex and Shimadzu to provide robust and dependable detectors that meet the rigorous demands of modern analytical laboratories. ALT offers a selection of pre-owned and refurbished detectors, each backed by a standard 90-day warranty that can be upgraded to a three-year warranty, along with ALT's lifetime support. Because they're refurbished, detectors from ALT are typically priced 50%-80% lower than the cost of new instruments, helping labs stretch their budget further without compromising on quality. - Less
