Normalization, baseline correction and alignment of data to assess changes in volatile production during infection of potato plants by Phytophthora infestans

摘要

One of the most time consuming steps in comparing chromatographic profiles is the manual identification of specific peaks in the paired chromatograms. Software has recently been developed to enhance this procedure. For this paper, results from manualpeak selection performed during previous research were compared to the outcome of the "MetAlign~(TM)" software package. This confirmed the discrimination and identification of three volatile compounds related to Phytophthora infestans infected potato plants. Automation of the matching procedure allows the creation of field sensors based on commercially available field-portable gas chromatographic equipment for detection of the disease in the field.
