Coulter Counter Model `S' System

An evaluation of the Coulter S counter.

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...

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...

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...

Estimation of lymphocyte percentage and number on the Coulter Counter, Model S Plus Phase II.

The Coulter Counter Model S Plus Phase II provided precise measurements of lymphocyte percentage and count and carry-over was negligible. Lymphocyte percentage values agreed well with those from the stained blood film except when the percentage was high and in these circumstances the instrument gave underestimates. When making artificial mixtures with increasing lymphocyte count a progressive u...
