Used to process priority stat samples and the fastest way to process a sample.
STAT table
the sample probe/liquid level detector dispenses samples and or diluent, and detects liquid level. Sample is aspirated from the tube/cup and dispensed into the cuvette wheel
Sample transfer unit
Two reagents probe/liquid level detectors dispense reagent and or diluent, and detect liquid level. The probe assemblies are designed for up and down collision detection. Reagent is aspirated from R1 and R2 compartment and dispensed into the cuvette wheel.
Reagent transfer unit
Mix bars used to mix the reagent and sample in the cuvette
Mixing unit
Consist of a halogen lamp, lenses, a diffraction grafting, and a photodetector to measure the amount of light transmitted through the reaction solution in the cuvette
Photometry unit
Cleans, rinses, and dries the cuvettes automatically
wash nozzle unit
Define ISE unit
Diluted samples is passed through sodium, potassium, and chloride ion selective electrode to determine the concentration by comparing the electrical potential different to the reference electrode.
The screen to check system messages relating to sample status and analyzer status.
Home outline
Check analyzer status menu: Blue
no error
Check analyzer status menu: yellow or orange
non fatal error. the analyzer can be started
Check analyzer status menu: Red
Fatal error. The analyzer can’t be started
3 important sample requirements for the instrument to sample correctly.
• should not contain fibrous material or fibrin, except for WB. • No air bubbles • Dispense sample volume in the quantity required for analysis plus the dead volume
Rack colors: white
used for analyzing routine samples
Rack colors: Blue
used for calculation of reagent blanks for creation of calibration curves
Rack colors- yellow
used for creating of calibration curves
Rack colors- green
used for analysis of QC samples
Rack colors- orange
used for manual repeat run analysis
Rack colors- red
used for emergency sample analysis
Daily variation chart for QC- green
normal data
Daily variation chart for QC- yellow
data outside the range of the single check level programmed in QC specific
Daily variation chart for QC- orange
abnormal data (data not included in the QC statistical values)
What colors do the operator observe on the analyzer maintenance screen if the analyzer requires maintenance and what are the meanings of the colors?
Orange- over due Yellow- expiring The colors for daily maintenance appear 3 hours before the maintenance check.
List 3 reasons that teh instrument may not be able to calculate a result
• mechanical error has occurred • outside fo cuvette walls or the cuvette wheel is wet • in the rate rxn, fewer than 3 photometric readings statisfy the assay creteria specified in teh specific test parameters
List the first possible causes and corrective actiosn to be taken for the errors
sample can be severly lipemic, icteric, hemolytic or can contain excessively large amount of the analyte being tests. dilute the sampel and run the test again.
