For example, we have built unique probes for real - time NMR studies of catalysts under operating conditions, single - particle laser ablation mass spectrometers for analysis of aerosol particles, and the nanospray desorption electrospray ionization instrument for highly sensitive analysis of minute samples.

The most broadly useful methods for chemical and biochemical samples use electrospray ionization - mass spectrometry (ESI - MS). (pnnl.gov)
He adds that the microscope's electron beam is more powerful than natural settings, but the gelling effect could affect the lifetime of electrospray thrusters in low - Earth and geosynchronous orbit. (sciencedaily.com)
