Particle-size analysis of aeolian dusts, soils and sediments in very small quantities using a Coulter Multisizer
This paper evaluates the Coulter Multisizer for sizing soils, aeolian dusts and other sediments which are only available in small quantities.

The granulometry of samples of marine and estuarian slime has been measured using two different methods. The first uses sedimentation (Sedigraph 5000 E) while the second counts the particles (Coulter Counter TA II). A good correlation of the results
of the two machines exists for the fraction between 50 m and 2 m and a reasonably good correlation exists for smaller particles, in consideration of a modification of the method of extrapolation of the HP 87 programme of the Coulter Counter.

Results of a traditional sedimentation technique for grain-size analysis (the sieve-pipette method) were compared with those of a laser diffraction grain-size analyser, the Coulter LS-100. Milled quartz samples and silty soil samples were used

Des analyses microgranulométriques de seston récolté en baie du Mont Saint Michel, effectuées à l'aide d'un compteur de particules Counter Coulter TA 2 ont fait l'objet d'un traitement informatique par application du logiciel d'analyses

Statistique traditionnelle, mode et analyse multivariée en granulométrie. Le mode indique les changements granulométriques dans le profil. L'analyse multivariée est utilisée sur les résultats du compteur Coulter, et révèle l'intérêt des limons
