Why water purity matters

ELGA LabWater
15 Nov 2024

Water is essential to the pharmaceutical industry. The quality of the water must be controlled throughout the production, storage and distribution processes, particularly for microbiological and chemical contaminants.

One of the most common techniques used in pharmaceutical production to verify drug purity is high performance liquid chromatography (HPLC). Due to the detailed analysis HPLC can generate, purified water is crucial for obtaining clear HPLC data. Explore how important purified water is in HPLC analysis, and discover how to avoid errors such as ghost peaks from dissolved compounds or blockages from microorganisms.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.HPLCHigh-performance liquid chromatography (HPLC) is a technique for separating, identifying, and quantifying components in mixtures. It is widely used in chemical, pharmaceutical, and environmental analysis to ensure purity and identify unknown compounds.
