Abstract
In an embodiment of the present ambient ionization experiment, the abundance of background chemicals relative to ions of interest is decreased by pulsing the carrier gas used to generate the excited species directed at the sample. The excited species are stepwise directed at the sample reducing the overall abundance of background chemicals introduced into the ionizing region. In an embodiment of the present ambient ionization experiment, the combination of stepping the sample in front of the excited species and pulsing the carrier gas used to generate the excited species increases the sensitivity of detection.
