2.3 operation
The analyzer is a self sufficient system that uses some peripherals, such as Mo-
nitor, Mouse, keyboard and printer.
The analyzer consists in three parts:
-
Reagent plate Chamber:
plate containing 30 On-line reagents with a choice to
cool or leave the reagents at room temperature.
- Sample plate: consisting of 4 segments each holding 10 primary
tubes and 10 small plastic cups for automatic pre-di-
lution. The center of the plate is reserved for 4 STATS,
and 16 places for Standards and controls.
- analytical System: consists of a reaction plate with 39 quartz cuvettes,
sitting in a liquid bath at 37°C. A built-in multi-filter
photometer measures the mAbs of the samples di-
rectly in the cuvettes. A built-in Wash system auto-
matically washes and dries the cuvettes after use for
a continuous operation.
A reagent probe (with a built-in liquid level sensor) aspirates the reagent and
transfers it into the quartz reaction cuvette. The Reagent is incubated in the
liquid bath at 37°C for 90 sec. During its incubation time, it is measured (this
becomes the reagent/cuvette BLANK for each test).
The Sampling Probe (with its built-in liquid level sensor and mixer) aspirates and
deposits the sample by mixing i into the warm reagent to start the reaction.
Both Sampling and the Reagent arms are automatically washed both internally
and externally, dried and are ready to prepare the next sample.
The 12 seconds operational cycle consists in:
- a) Reagent aspiration, dispensing and measurement Reagent/Cuvette
BLANK
- b) Sample aspiration, dispensing, mixing, a sample measurement
- C) A final sample measurement and calculation
- d) Wash and dry cuvette
-
e)
Measurement of 20 samples in each cycle. (Each sample is measured every
24 sec – 2 working cycles)
