Errors in differential infrared carbon dioxide analysis resulting from water vapor.

abstract：:A short list of the twentieth century's dominant figures in photosynthesis would unquestionably include Otto Warburg. One of his many discoveries, the 'bicarbonate effect' remains a lasting puzzle to his heirs in the field. Recent developments in this area of research have renewed interest and call for a re-examinatio...
