standard for the d.c. impedance, r.f impedance and optical light scatter parameters of the

VCS module of Coulter® Models STKS, MAXM and GeneS Hematology Analyzer

systems. Models STKS and MAXM analyzers equipped with 5-part differential

capability only require aspiration of the CDS LTX-Control Latex Particle Suspension

through the secondary mode aspiration inlet with the analyzer set to function F55. STKS

and Gene$S analyzers equipped with 5-part differential and reticulocyte capability require

aspiration of the CDS LTX-Control Latex Particle Suspension through the secondary

mode aspiration inlet with the analyzer set to function F57.
