Water HPLC Ultra Pure
Water HPLC Ultra Pure (CAS 7732-18-5) is a high-grade solvent rigorously purified for critical analytical applications.
Description
Water HPLC Ultra Pure, identified by CAS number 7732-18-5 and chemical formula H2O, represents the pinnacle of solvent purity engineered for demanding High-Performance Liquid Chromatography (HPLC) and other sensitive analytical techniques. This product undergoes an extensive purification process employing multiple stages, including deionization, reverse osmosis, photo-oxidation, and distillation, followed by microfiltration to eliminate trace organic compounds, inorganic ions, particulates, and microorganisms. The stringent quality control measures ensure ultra-low levels of absorbance in the UV range, minimal residue after evaporation, and consistently low conductivity. This highly purified water serves as a foundational component in laboratory settings where background interference must be meticulously minimized, thereby enhancing the accuracy, reproducibility, and sensitivity of analytical results across a broad spectrum of scientific disciplines. Its exceptional purity makes it indispensable for methodologies requiring precise and uncontaminated matrices.
Applications
Water HPLC Ultra Pure is indispensable across numerous scientific and industrial sectors. Its primary application is as a mobile phase component or diluent in High-Performance Liquid Chromatography (HPLC), enabling accurate separation and detection of analytes in pharmaceuticals, biotechnology, food and beverage analysis, and environmental monitoring. It is also critical for sample preparation in mass spectrometry (MS) and inductively coupled plasma mass spectrometry (ICP-MS) to prevent contamination and ensure method integrity. Furthermore, it is utilized as a high-purity solvent for reagent preparation, calibration solution formulation, and as a blank in spectrographic analyses where even trace impurities can compromise results.
Storage & Handling
Store in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials. Minimize exposure to air to prevent contamination. Use clean, dedicated equipment for transfer. Avoid prolonged contact with reactive metals or acidic/alkaline substances. Maintain good laboratory hygiene practices.
