Abstract
Techniques for performing data acquisition and analysis are described. A multi-mode acquisition strategy may be performed which iteratively selects mass isolation windows of different sizes in different scan cycles to acquire experimental data. The mass isolation windows selected may provide for acquiring elevated energy scan data for a defined set of m/z values. Single scan data analysis may be performed. Data analysis may include forming precursor charge clusters, chaining precursor charge clusters having the same mass to charge ratio to form peaks profiles, and using criteria to align precursor and product ions of the experimental data. Unsupervised and supervised clustering may be performed using a database and composite ion spectra formed from experimental data. Also described are a small molecule acquisition enhancement and additional techniques applicable for biopharmaceutical and other applications.
