WebMS requires expensive instrumentation and maintenance costs can be high. The charged aerosol detector (CAD®) is a mass-sen- sitive detector capable of directly measuring any nonvolatile and many semivolatile analytes. WebA common high performance liquid chromatography (HPLC) method uses fluorescent labelling, but derivatization procedures can be time consuming. Presented here is an …

WebThe CAD detector was developed to allow for near-universal response between analytes separated by LC, but it has been noted that differences still exist between analytes, which need to be considered in CAD quantitation [33,34]. We, therefore, began by studying the HILIC-CAD response factors of common PSTs for which CRMs were available. As a general recommendation for HILIC standard methods, select a 100 or 150mm long column, packed with 3 - 5µm particles and with a 4.6mm id, if using UV detection. If HILIC is coupled to MS or CAD detection, use a smaller column, e.g. 100 x 2.1mm or 50 x 2.1mm, packed with 3-5µm particles. black and brass vitra wall clock https://frenchtouchupholstery.com
