Configuration : Console type automatic analyzer, with analytical and operation units integrated Principle : Discrete type, random access, single-line multi-analysis system; entire reaction monitoring system Analytical methods : Colorimetry (absorbance measurement), ion selective electrode method (ISE; option) Throughput : Colorimetry ; 200 tests/hr (Photometry only max. 300 tests/hr inclusive of ISE) No. of analysis item s : Colorimetry ; 36 ISE ; 3 (Na, K, Cl) Serum indexes ; 3 Calculation item s ; 8 Reaction time : 10 minutes max.; 3, 4, 5, 10 minutes for concentration calculation (same as Model 7070/7170) Measurable samples : Serum (or blood plasma) and urine; one sample kind per channel Application : Emergency (stat) and routine analyses Test item selection : Via entry from operation panel, entry from system interface, entry from no. of items settable (11 kinds), Sampling mechanism : Pipetter driven by stepping motor 2 to 50 μ L of sample/test (in 0.1 μ L steps) Pipetting mode : Normal ; prescribed volume discharged at cell bottom Aqueous sampl e; system water solution for sample probe internal rinsing usable as STD-1 Sample pre-dilution not performed Insufficient sample detectio n : Resistance detection method Sample ID : Barcode reader (option) Following code shemes are usable in combination; CODE 39, CODE 128, INTERLEAVED 2 OF 5 , NW7 (Modulas 10, Modulas 16) Automatic rerun : Auto rerun function not provided Stat sample analysis : Routine sample analysis interruptible for stat sample analysis Sample carryover : Sample carryover evasion function available; 2 kinds of detergents settable on sample disk inner row, Reaction disk : Turntable type disk (10-minute reaction per rotation) Reaction cell : Optical path length 6 mm (area 6 × 5 mm) No. of reaction cells : 48 Reaction cell control : One rotation + one pitch feed (18 seconds) Sample pipetting positio n : One position (fixed) Reagent pipetting positio n: One position (fixed) Reaction temperature : 37 ± 0.1 ° C (warm water circulating system) Stirring : By means of stirring rod rotation Timing for stirring; after each addition of R1,R2,R3 Stirring possible for a minimum volume of 100 μL, 1 -4 1.4 Reaction System Reaction disk : Turntable type disk (10-minute reaction per rotation) Reaction cell : Optical path length 6 mm (area 6 × 5 mm) No. of reaction cells : 48 Reaction cell control : One rotation + one pitch feed (18 seconds) Sample pipetting positio n : One position (fixed) Reagent pipetting positio n: One position (fixed) Reaction temperature : 37 ± 0.1 ° C (warm water circulating system) Stirring : By means of stirring rod rotation Timing for stirring; after each addition of R1,R2,R3 Stirring possible for a minimum volume of 100 μ L Stirring position : One position (fixed) Reacting solution volum e : Minimu m ; 250 μ L (minimum required volume for photometry) Maximu m; 500 μ L (temperature control, rinsing upper limit) Photometric position : One position (fixed) Cell rinsing : After completion of photometry (rinsing 3 times; rinsing with detergent not performed) Carryover evasion : Rinsing for carryover evasion possible; throughput may decrease by specifying cell carryover evasion
