The objective of the study was to maximize throughput without introducing a significant number of additional chromatographic co-elutions not separable by deconvolution, whilst transitioning from a standard 30 m column to a 15 m column.
LECO's proprietary deconvolution software, embodied as NonTarget DeconvolutionTM, was leveraged to maintain exceptional peak fidelity of the qualitative analysis, while the Target Analyte Find feature was utilized for robust quantitation and to establish method detection limits for organonitrogen pesticides spiked in QuEChERS strawberry extracts.
