[Critical study of a new method for measuring total CO2 in plasma (author transl)].
A new analyser for total CO2 in blood--Ericsen E-100--has been tested and its performances compared with those of the manometric Van Slyke apparatus. Ericsen E-100 makes it possible to measure very small samples (50 microliter) in a short time (35 s). It appears that Ericsen E-100 underestimates total CO2; the higher the total CO2 the larger the error. Simple improvements are suggested, especially concerning the way injection is performed in the reaction chamber.
