DESI is a technique typically used for imaging style applications, investigating compound localization within a sectioned tissue or on a sample surface.
DESI can also be used as a direct rapid sample delivery source for screening a variety of samples such as blood product lipid profiling, drug library screening or cell culture monitoring. This technique could also potentially increase speed of sample analysis in applications such as real time reaction monitoring or bioreactor upstream and downstream sample analysis.
In order to maximize sample throughput, sample acquisition occurs with all data a single line pass and single data file, rather than as individual per-sample acquisitions.
To then simplify subsequent data analysis, as most processing software expects each sample to be a unique data-file, RapidExtract segments the data into individual per-sample .raw files suitable for downstream analysis.
