Peak Detection Algorithm Based on Second Derivative Properties for Two Dimensional Ion Mobility Spectrometry Signals

Abstract: Abstract. In this paper we propose a novel peak detection algorithm for 2-dimensional analytical data. The proposed algorithm utilizes the properties of the second derivative and curvature of (regular) surfaces to perform peak detection. Raw data used in this study for performance demonstration were obtained by a hyphenated system called gas-chromatographic column ion mobility spectrometer (GC-IMS). GC-IMS is a two stage technique for separation of gasphased (organic) compounds. Despite the good performance of… Show more

“…Furthermore, the possibility of false positive responses in IMS determination may result in the presence of different compounds with a similar 1/ K 0 value. Peak detection algorithm for two‐dimensional analytical data based on derivative algorithm can minimized those limits and second‐derivative algorithm was most used . To increase the discrepancies of these two edible oils, first‐ and second‐derivative algorithm were involved, which were provided by the IMS work station software.…”

“…derivatives (Arteaga-Falconi et al 2015;Slodzinski et al 2013) especially when considered in conjunction with the structure of p(C) itself. These results are not sensitive to correlations because p(C) does not depend upon whether the observed values are clustered or spread out in time or space.…”

“…The first and most obvious one is to look for descending zero crossings of the first derivative. Sometimes, though, the peaks are hidden, so one must resort to looking at the second derivatives (e.g., Arteaga-Falconi et al 2015;Slodzinski et al 2013). Examples of the usefulness of this approach are illustrated below.…”
