ABSTRACT:
The invention features an improved interface between a microfluid chip and a mass spectrometer. It has been found that by connecting a very fine tube (or "interface tip") to an outlet port of a microfluid chip, the sensitivity of the mass spectroscopy analysis of materials exiting the outlet port of a microfluid chip is greatly enhanced.
