Measuring Analyte Concentrations in Liquids

InactiveUS20080137065A1Higher kinetic energy mixingSmall dropletSamplingComponent separationElectrical mobilityDroplet size
A high performance liquid chromatography system employs a nebulizer with a flow restriction at the exit of its mixing chamber to produce finer droplets, and an adjustable impactor for increased control over droplet sizes. Downstream of the mixing chamber, the nebulizer can incorporate tubing that is permeable to the sample liquid, to promote aerosol drying through perevaporation. A condensation particle counter downstream of the nebulizer uses water as the working medium, and is adjustable to control threshold nucleation sizes and droplet growth rates. A particle size selector employing diffusion, electrostatic attraction or selection based on electrical mobility, is advantageously positioned between the nebulizer and the CPC.

Method and system for vacuum control

Methods and systems are provided for adjusting a fuel injection split between a direct injection and a port injection based on engine vacuum demand. When more intake manifold vacuum is required, relatively more direct injection is used to take advantage of the associated throttling for generating vacuum. The vacuum may then be used for canister purging, crankcase ventilation, or actuating an engine vacuum consumption device.

A liquid atomizing nozzle

The present invention provides a nozzle capable of multiple atomizing steps of a liquid. In one configuration the nozzle provides atomization of a liquid fluid in a first direction and subsequent post atomization of the same liquid in a second direction to form a counter-flow nozzle. Accordingly, the liquid fluid to be dispensed is atomized in at least two separate stages causing improved atomization and the creation of particulate matter size of the liquid within a specified droplet spectrum. Furthermore, the present invention provides these features through an improved and simplified design providing potential cost savings to the end user due to the more effective operation of the nozzle and more efficient dispensing of fluid agents.
