An assessment of the Coulter counter model S

An evaluation of the Coulter S counter.

An evaluation of the Coulter model S.

This report is concerned with the performance of the fully automatic counter Coulter model S. The apparatus consists of four units two of which, the electrical power and the vacuum and air pressure units, may be placed under the bench. The counter itself and its printout must be sited side by side on the bench (Fig. 1). Apart from what can be seen on the front, the cabinet conceals a mass of el...

Evaluation of the Coulter Counter S-Plus VI

This article reports an evaluation of the Coulter Counter model S-Plus VI automatic analyser for haematology, and data are presented on linearity, carry-over, precision, accuracy and stability of the instrument, when compared with a model S-Plus IV/D.The three-part differential count provided by Coulter S-Plus VI has been compared with manual eye counting. The results show a good agreement with...

Diagnosis of a-thalassaemia trait from Coulter Counter 'S' indices

A number of patients of Mediterranean and Asian origins were found to have unexplained microcytic hypochromic red blood cells. Iron deficiency and fl-thalassaemia trait were both satisfactorily excluded in all of them. The haematological indices of these patients, obtained on a Coulter Model 'S' Counter, were found to be very similar to those seen in obligatory heterozygotes for oc-thalassaemia...

A new method of quality control for the Coulter Model S Counter.

After evaluation and comparison of many different methods, Sornas developed and recommended the sedimentation method for cytology of CSF (S6rnas, 1967; Aronson et al., 1974). The cytocentrifuge method has also been recommended recently by a few investigators (Drewinko et al., 1973; Evans et al., 1974). We have found much cell distortion with the cytocentrifuge method and very poor yields, as ha...
