A gas analyzer is provided which is comprised of two gas sample flow loops joined at an angle to each other, one being an eductive loop that originates and returns to the chamber or conduit from which a gas sample is to be drawn and the other being a convective loop that joins in fluid flow communication with the eductive loop at a point upstream from its eductor device.

A method for sampling a gaseous fluid in a chamber comprising, withdrawing a continuous flow of sample gas along a first loop type flow path extending from said chamber through a flow inducing device and back to said chamber, joining inlet and outlet legs of a second loop type flow path at substantially the same location along the length of said first loop type flow path, positioning said second loop type flow path upstream of said flow inducing device, withdrawing a portion of said sample gas along said second loop type flow path through said inlet leg thereof, electrochemically sensing the condition of said gas in said second loop type flow path, and returning said sensed gas through said outlet leg of said second loop type flow path to said first loop type flow path upstream of said flow inducing device.
