The plume of neutral molecules, clusters, and particles can be ionized with a second laser or through interactions with charged particles or ions. Laser post-ionization can be done under vacuum or atmospheric pressure but higher pressures are needed for interaction with particles or gas phase ions.<\/p>\n<\/div><\/div>\n\n\n\n

A laser can be used to ablate material that merges with highly charged droplets from an electrospray. With this approach, materials can be analyzed under ambient conditions with the spatial resolution afforded by a focused laser.<\/p>\n<\/div><\/div>\n\n\n\n
