• Syringe pumps control the volume and flow rate of reagents through the pneumatic
components.
• Shear valve is an integrated multi functional valve for segmenting precise volumes of
blood.
4.3 Small Sample Mode (SSM) – optional
Instruments which have the small sample module (SSM) installed can be used for taking
sample from a small amount of whole blood sample, which is not enough for normal
sampling.
• SSM measurements are only open vial measurements.
• At least 250 µl of sample is necessary for reliable sampling.
• The analyzer will aspirate 25 µl of whole blood and put it in to the pre-dilution
chamber to dilute it to 1:6.
• After pre-dilution, the needle will take 100 µl of diluted sample into the shear valve
and ´ELite 5´ is going to proceed with the normal measuring process.
