Abstract

High throughput laser desorption (LD) mass spectrometry was used to study the rapid detection of malaria parasites in blood. The LD mass spectra of intact heme contained a series of structure-specific ions and signal intensities were quantitatively correlated with the sample parasitemia. Pulsed ion extraction was optimized for ion focusing and transmission at m/z 1200. A unique time of flight (TOF) multi-array system for increasing the throughput of blood screening for malaria was tested by simultaneous acquisition and analysis of multiple mass spectra.
