Abstract: Metabolic phenotyping is a highly informative approach in systems biology research that enriches the understanding of the metabolic mechanisms of infectious disease pathogenesis.
Advancements in quadrupole-time-of-flight (QToF) technology have enabled the use of high-resolution accurate mass instruments for both discovery and quantitative analyses [1]. However, metabolite concentrations can vary drastically between individuals and if sample volumes are limited, the dynamic range and sensitivity of the instrument become critical. Of significant influence to metabolite sensitivity is the design of the ionization source and efficient generation of charged ions.
Here, we determine if improvements in sensitivity and reproducibility occur in the newly developed ion source vacuum-insulated-probe heated electrospray ionization source (VIP-HESI) and compare the results to a previously validated method for detection 30 physiological biogenic amines on an Apollo II ESI source coupled to a timsTOF Pro.
