LC eluent is vaporized and mixed with nebulizer gas in the vaporizer section and the vapor is sprayed out from the chip. Nonpolar and polar analytes can be efficiently ionized in the gas phase by atmospheric pressure photoionization (APPI) as demonstrated with polycyclic aromatic hydrocarbons (PAHs...
Acapillary tubewith the bottom end immersed in a water container. 2. The top end of the capillary tube is close to a Venturi constriction (Fig. 9.7). Mechanism of action 1. A high-pressuregas flowsthrough the Venturi, creating a negative pressure. ...
1. A method of reducing sample deposition on the sampling orifices of an inductively coupled plasma mass spectrometer having a nebulizer, the method comprising: introducing a nebulizer add-gas into the nebulizer, the add-gas comprising SF6. 2. The method described in claim 1, wherein the SF6...
not available for EP0573457of corresponding document: WO9215354 A nebulizer for introducing a liquid in fine droplet form into a gas flow, including a reservoir (24) for the liquid, an outer wall (16), a base wall (17) of generally conical shape, the base wall extending from a lower ou...
The unique design consists of a high-efficiency MicroMist nebulizer, low volume, on-axis spray chamber, and a MicroJet gas adapter that entrains and shapes the nebulizer aerosol plume, reducing cell deposition onto the spray chamber walls and increasing transport efficiency. Laser Ablation is a ...

Discrete frequency noise in the aerosol generated by a Meinhard nebulizer or a direct injection nebulizer was primarily caused by pulsation in the liquid flow from the pump. By use of a pulse-free pump, such as a gas displacement pump or a dual piston pump for liquid chromatography, the ...
Plots of signal intensity as a function of RF power, nebulizer gas flow rate, and intermediate gas flow rate are shown in FIGS. 4-6 for several elements across the mass range using the HEN19and for an optimum solution uptake rate of 85 μL/min. The short torch adapter design10when used...
