A typical qualitative analysis of complex samples like herbal extraction samples using tandem quadrupole instruments can require multiple injections. Comprising samples run in MS scan mode and then further injections in daughter ion mode. For a complex sample creating the daughter ion method can be a laborious process. Each parent needs to be manually identified and a separate daughter scan created for each parent. Use of survey scan eliminates the need for a second acquisition. Survey scan allows automatic switching from one scan type to another based on various user defined triggers. For improved sensitivity survey scan can also utilize ScanWave for the MS and DS modes.
