Abstract

High-throughput MALDI-TOF-MS-based detection of biological agents by using fully-automated peak extraction and baseline estimation method was discussed. For the experiment, MS signal was first deconvolved into a baseline and a set of elemental spectral lines. The baseline was then estimated using a novel non-linear, low-pass filtering algorithm. It was suggested that the technique yields the set of peak centers, signal/noise values, and uncertainities required for peak-matching-based algorithms for agent detection and identification.
