Sysmex XS-1000i Automated Hematology Analyzer
Fluorescent flow cytometry and advanced cell counting in a space-saving footprint makes the Sysmex® XS-Series Automated Hematology Analyzer an excellent choice for laboratories that have smaller sample volumes. Available with and without an auto sampler, the XS-1000i offers 21 testing parameters and closed tube sampling to assure operator safety. It requires less than four feet of counter space and uses only 20 µL of sample.

Proven Technology
Red Blood Cells and Platelets RBCs and PLTs are counted in a dedicated channel using the direct current detection method with hydrodynamic focusing technology to minimize coincidence or recirculation. Automatic discriminators separate the two cell populations based on complex algorithms. The intensity of the electronic pulse from each analyzed RBC is proportional to the cell volume. The hematocrit (HCT) is directly determined based on the count and volume detection of each individual RBC. Even with samples at extremely low or unusually high concentrations, the Sysmex cell counters analyze RBCs and platelets with uncompromised precision and accuracy. Hemoglobin Analysis - The Sysmex sulfate lauryl sodium (SLS) method for hemoglobin analysis is a cyanide-free method. Hemoglobin is determined in a separate channel, minimizing interference from high leukocyte concentrations. The SLS method shows excellent correlation with the reference method. With very short reaction times, this method is ideal for high throughput analyzers.Fluorescent Flow Cytometry - Traditional flow cytometry is considered the best method for the differentiation of cell populations. However, traditional flow cytometry requires the use of costly antigen-antibody reagents and the procedures can be cumbersome and time consuming. Fluorescent technology enables the XS-1000ito reliably differentiate normal WBC populations from abnormal WBC populations. The sensitivity of the unique application of fluorescent flow cytometry gives the lab a high level of confidence in reporting accurate WBC Differentials, even on critical patient samples when the WBC count is low. WBC Differential - Fluorescent labeling is a milestone for the routine WBC differential. Fluorescent measurement reveals the nucleus-plasma ratio of each individually stained cell, enabling the XS-Series analyzers to differentiate five reportable WBC populations. The combination of side scatter (inner complexity of the cell), forward scatter (volume) and fluorescence of nucleic acid material determines the classification of each WBC. The XS-Series utilizes an Adaptive Cluster Analysis System (ACAS) instead of conventional discriminators to separate cell populations into well defined clusters. This three-dimensional measurement of WBC provides an accurate and precise differential, even in highly pathological samples.
