<p>An NIR sampling system designed to provide a stable gasoline sample stream to an NIR analyzer. Preferred design elements include a temperature-controlled stream moving through an inverted coalescer whereby gas bubbles are removed through an overhead stream. Elevated pressure is used to reduce degassing as well. Two or more prototype fuels can be injected to calibrate the instrument over a range and prove accuracy before and/or after analysis of a sample.</p> |
