UPLC Analysis of Benzalkonium Chloride (BAC) in Consumer Products using ACQUITY UPLC CSH C18
7 May 2013This application note presents an alternative to the USP method for the quantitation of Benzalkonium Chloride (BAC). The analysis of BAC is performed with a Charged Surface Hybrid (CSH) C18 stationary phase under UPLC® conditions. Results demonstrate improved peak shapes with significant reductions in both analysis time and solvent consumption.

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. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Waste WaterEnvironmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Bacterial DetectionBacterial detection uses methods such as cell culture, microscopy, and biochemical assays to identify harmful or beneficial bacteria based on their morphological and metabolic charactersistics. These techniques support disease diagnostics, food safety, and microbial research.
