초록 ▼

Liquid from a liquid chromatograph or other sample source, preferably assisted by a high velocity coaxial gas jet, is sprayed through a capillary tube producing a flow in a first direction of charged droplets. A flow of heated gas, in a second direction different from the first direction, intersects the droplet flow at a region upstream of an orifice. The flows mix turbulently, with the second flow helping to evaporate the droplets to produce ions and helping to move the evaporating droplets toward the orifice, providing a focusing effect. Ions are drawn through the orifice into a mass analyzer and analyzed. Alternatively the flows of liquid and heating gas can be directed toward each other and at right angles to the axis through the orifice, and the inhaling effect of the orifice can be used to draw droplets toward it, or a third gas flow can be used for this purpose. The heated intersecting gas flow typically provides an increase in sensitivity (ion counts per second) of between 10 and 100 times. Heating the droplet plume also allows controlled desaturation of ions and in increase in the number of charges on them, without degrading the ions.

대표청구항 ▼

A method of analyzing ions from trace sample molecules in a liquid, comprising the steps of: (a) providing a chamber having a capillary tube therein, said capillary tube having a free end, said chamber having an orifice member spaced from said free end and having an orifice therein, (b) directing said liquid through said capillary tube and out said free end, (c) generating an electric field in said chamber between said free end and said orifice member, (d) producing from said free end a first flow, of charged droplets of said liquid, and directing said first flow in a first direction, (e) producing a second flow, of gas, and heating said second flow, (f) directing said second flow in a second direction different from said first direction for said second flow to intersect said first flow at a selected region for turbulent mixing of said first and second flows in said region, (g) the heated gas from said second flow acting to assist evaporation of the droplets in said first flow to release ions therefrom, (h) and drawing at least some of the ions produced from said droplets through said orifice into an analyzer located outside said chamber beyond said orifice member.
