    Abstract: In an axial-flow cylindrical preparative chromatography column that utilizes a piston to close off the top of the resin space inside the column and thereby eliminate void spaces at the top of the resin, a sight glass is incorporated in the column wall to allow monitoring of the packing height and density as the packing material is being placed inside the column, as well as the position of the piston head relative to the packing while the piston is being lowered to consolidated and/or compress the packing. By observing the column interior through the sight glass, the operator can assure that the column receives a more uniform packing density and can minimize the risk of damage to the packing material by excessive force from the piston head.

    Abstract: L'invention concerne un procédé de détermination des fractions volumiques respectives d'hydrocarbures saturés, oléfiniques et aromatiques dans un échantillon d'un produit pétrolier liquide distillant en dessous de 315 °C, dans les conditions opératoires définies dans la norme ASTM D 1319-03, lequel procédé se distingue du procédé normalisé par le fait que le relevé des résultats d'analyse et l'exploitation de ceux-ci se fait non pas par un opérateur humain, mais au moyen d'un système d'acquisition et de traitement d'images numériques comprenant au moins une caméra numérique à dispositif à transfert de charge (CCD) et un ordinateur avec un programme informatique de traitement des images numériques enregistrées.
