The Corona Ultra RS Charged Aerosol Detector (CAD) is a cutting-edge detector designed to enhance the capabilities of ultra-high-performance liquid chromatography (UHPLC). Utilizing charged aerosol detection technology, the detector offers unparalleled sensitivity and reliability across a diverse range of applications, making it a favored choice for pharmaceutical companies, food and beverage testing, specialty chemicals, and biofuels analysis.
The Corona Ultra RS provides a consistent response that is largely independent of the chemical structure of analytes. This feature allows for the detection and relative quantification of non-volatile and semi-volatile compounds without the need for analyte-specific standards. With a dynamic range spanning over four orders of magnitude, the detector is highly effective for both trace analysis and routine quality control. Additionally, its compatibility with the most advanced UHPLC systems, such as the UltiMate® 3000 RSLC system, ensures versatility and ease of integration into any laboratory environment.
