Apparatus for performing quantitative analysis of gaseous mixtures

Claim 1

A MULTIPLE ANALYZER WHICH COMPRISES, IN COMBINATION, MEANS FOR SUPPLYING TWO RAY BEAMS HAVING AT LEAST APPROXIMATELY THE SAME WAVELENGTH COMPOSITION AND THE SAME INTENSITY, A SERIES OF AT LEAST FOUR CHAMBERS DISPOSED ONE BEHIND THE OTHER ACROSS THE PATH OF ONE OF SAID BEAMS, MEANS FOR FEEDING THE FIRST AND THIRD CHAMBERS OF SAID SERIES WITH A SAMPLE OF THE MIXTURE TO BE ANALYZED, THE SECOND CHAMBER OF SAID SERIES COONTAINING ONE OF THE COMPONENTS OF SAID FIXTURE, AND THE FOURTH CHAMBER OF SAID SERIES CONTAINING ANOTHER COMPONENT OF SAID MIXTURE, SAID SECOND CHAMBER CONTAINING THAT OF THESE TWO COMPONENTS WHICH REQUIRES, FOR CORRECT ANALYSIS, A SMALLER THICKNESS OF AID SAMPLE OF MIXTURE THAN THE OTHER COMPONENT, THIS THICKNESS BEING THAT OF THE FIRST CHAMBER, AND SAID THIRD CHAMBER BEING OF A THICKNESS WHICH, ADDED UP TO THE THICKNESS OF SAID FIRST CHAMBER, GIVES AT LEAST APPROXIMATELY THE BEST POSSIBLE THICKNESS VALUE FOR THE ABSORPTION OF THE RAYS CORRESPONDING TO THE COMPONENT PRESENT IN SAID FOURTH CHAMBER, A SECOND SERIES OF CHAMBERS DISPOSED ONE BEHIND THE OTHER ACROSS THE PATH OF THE SECOND RAY BEAM, THIS SECOND SERIES COMPRISING AT LEAST FIFTH AND SIXTH CHAMBERS CONTAINING THE SAME COMPONENTS AS THE SECOND AND FOURTH CHAMBERS, RESPECTIVELY, BUT NO MIXTURE SAMPLE RECEIVING CHAMBER, AND MEANS FOR COMPARING THE RESPECTIVE ACTION ON A GIVEN PHYSICAL FACTOR, RESULTING FROM THE AMOUNT OF RAYS ABSORBED BY THE CONTENTS OF SAID FIRST AND THIRD CHAMBERS, BETWEEN SAID SECOND AND FIFTH CHAMBERS AND BETWEEN SAID FOURTH AND SIXTH CHAMBERS, RESPECTIVELY.
