[Blood ethanol assay by gas chromatography]. / Dosage de l'éthanol sanguin par chromatographie en phase gazeuse.

Blood ethanol measurement can be performed by gas chromatography if the samples are diluted before tungstate-sulfuric acid deproteinization. A good knowledge of linearity area is needed for to obtain with this method the same results than with the oxydimetric method.

[Improved enzymatic method for determination of serum triglycerides with a centrifugal analyzer (author's transl)]. / Adaptations à l'analyse centrifuge d'une méthode enzymatique de détermination des triglycérides sériques.

The authors describe an enzymatic triglycerides method adapted to the Centrifichem Centrifugal Analyzer according to a two points kinetic process with a delayed initial reading. Such protocol eliminate the interfering substances with rapid kinetic specially free glycerol at low levels. Correlatively, the choice of the standard is very significative. The method is rapid and permits a good approach to triglycerides levels without arbitrary correction for free glycerol.
