System Summary
The Liasys analyzer performs up to 200 tests per hour (without ISE module), featuring continuous loading capability and computer-controlled analysis. It supports endpoint, kinetic, bichromatic, and differential assay types, with precision better than 1% CV at 3 µL volume.
Key Subsystems Covered:
Reaction Plate: 60 cuvettes, automatic washing/drying, 37°C temperature regulation.
Sampling Arm: Capacitive liquid-level sensing, reagent preheating, automatic washing, and variable volume diluter.
Photometer: Halogen lamp (6V/10W), double-channel interferential filter wheel (340–620 nm).
Optics & Electronics: Dual HITACHI H8/3048 microcontrollers, RS232/parallel ports, and programmable logic arrays for motor control.
Maintenance Modules: ISE (Na⁺, K⁺, Cl⁻ electrodes), pumps, solenoid valves, and peristaltic systems.
Diagnostic Utilities: Integrated CPU-level test routines for ADC, PWM, and motor driver verification.
Safety & Precautions
Covers chemical, electrical, and mechanical hazards, emphasizing:
Handling of reagents and biological samples.
Electrical isolation and grounding precautions.
Use of protective gear to avoid mechanical entanglement with probes or moving components.
