Immunoassay analyzer

Immunoassay analyzers are core clinical diagnostic instruments used for proteins, hormones, and infectious disease biomarkers with picogram-level sensitivity. High-sensitivity photomultiplier tubes (PMTs) and chemiluminescence signal chains are extremely vulnerable to power grid fluctuations, electrostatic discharge generated by rapid sampling mechanisms, and transient spikes on control and signal lines. YINT Electronics’ protection solutions integrate gas discharge tubes (GDT) for surge diversion, MOV varistors for energy absorption, TVS diodes for fast transient suppression, ultra-low capacitance ESD arrays for high-speed interfaces, and common-mode chokes to mitigate EMI noise — ensuring accurate signal reproduction and consistent batch-to-batch diagnostic results even in demanding clinical environments.
