Chemical analysis sample control

摘要: A method of controlling spectroscopic analysis in which a sample liquid concentrate form and containing an element interest, is nebulized carried into zone by pressurized support gas. The invention comprises regulating the flow rate gas to control density atoms present so as be within measurable range. controls uptake at nebulizer, that reduced dividing before nebulizer one part by-passes but nevertheless directed total remains constant. In apparatus for carrying out method, through automatically when overrange condition detected, correction factor applied read-out each reduction all rates representative quantity interest sample.
