Describe in detail how rotachii/hitachii 902 clinical chemistry analyzer is operated?

First enter the ID & name of patients. Then enter the position of sample tubes for patients. After that enter the list of the tests for each patient. Then enter the rack that containing samples tubes inside the machine. The analysis of sample tests started automatically.

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
