Sensitive, yet tough. That's nanoDESI. The nanospray Desorption ElectroSpray Ionization technique, a novel method created at Pacific Northwest National Laboratory to analyze tiny samples of atmospheric aerosols. This new technique requires no sample preparation and provides a reliable, simple way to introduce these samples into a mass spectrometer for detailed analysis of their molecular content. With nanoDESI, scientists are breaking the sensitivity limits of conventional approaches.
