Abstract
A system for producing a high precision blended gas product (BGP), the system comprising: a supply of a volatile analyte in liquid form; a supply of an inert carrier gas; a supply of at least one diluent gas; an analyte gasifier (AG) subsystem for receiving the volatile analyte in liquid form, nebulizing the volatile analyte and mixing the nebulized volatile analyte with the inert carrier gas so as to form an analyte gas stream (AGS); and a gas mixer (GM) subsystem for receiving the AGS from the AG subsystem and mixing the AGS with the supply of at least one diluent gas so as to produce the BGP, wherein the GM subsystem comprises: a gas analyzer (GA) for receiving the AGS and analyzing the same; a gas proportioner for receiving the AGS from the GA, receiving the at least one diluent gas, and proportioning the AGS and the at least one diluent gas based on the results of the GA so as to provide a proportioned AGS and a proportioned at least one diluent gas; and a gas mixing chamber for receiving the proportioned AGS and the proportioned at least one diluent from the gas proportioner so as to produce the BGP.
