ABSTRACT:
A device for interfacing between a microbore liquid chromatograph and a mass analyser. In such a device, liquid from the liquid chromatograph is sprayed through a stainless steel capillary tube into the atmospheric pressure ionization chamber of a mass spectrometer. A voltage of e.g., plus or minus 3 KV is applied to the stainless steel tube, and a nebulizing gas, e.g. nitrogen, is directed at high velocity past the tube tip through another tube encircling the stainless steel tube. The combination of the nebulizing gas and the electric potential disperses the liquid at room temperature into a fine mist providing an increased and more stable ion signal without thermal decomposition of the compounds being analysed.
