Which EMC (electromagnetic compatibility) devices are helpful for the design and modification of chemiluminescence immunoassay analyzers?

The core of the device's EMC design is to "create a quiet environment for optical detection." The PMT, its high-voltage power supply, and preamplifier must be housed in a fully enclosed metal shielded box, with only a small light-entry hole. All cables entering and exiting the box pass through a feedthrough filter. The sample tray and reagent tray drive motors should be located away from the detection chamber, and their drivers are powered separately through an isolation transformer. The heater of the incubation module uses PID control, and its SSR drive terminal is equipped with RC absorption. The instrument casing is grounded as a whole, and the internal structure uses a star grounding method to ensure the cleanest possible detection ground potential.
