Automatic immunoassay analyzer LYOFIA8

for clinical diagnosticmicrofluidicfluorescence

This device is based on fluorescence immunoassay technology and intended to be used in combination with the detection kits manufactured by our company to quantitatively detect analytes in human serum, plasma or other body fluid samples in clinical practice. And it is for professional use only, not for self-testing of untrained individuals, nor for near-patient testing. Contraindications: None. Analyzer Summary This device is a quantitative determination analyzer developed basing on modern optoelectronic technology and intended to be used in combination with fluorescent immunoassay strips to detect relevant parameters of human samples. The detection results could be used for clinical auxiliary diagnosis. The analyzer applies a time-resolved method for detection. The principle is to use the characteristics of the wide Stocks shift and long duration of the lanthanide elements labeled in the test strip, that is, after removing the excitation light, the lanthanide elements can still maintain the continuous emission of the emitted light for a long time. However, other substances that can be excited to emit fluorescence cannot generate emission light in a very short time after the excitation light is removed. It is the application of the time-resolved method for detection that after turning off the excitation light for a certain period of time, and after other interfering substances cannot generate the emitted light, the light intensity is read. Through the optimized design of the optical path and the amplifier circuit, the weak fluorescence emission light signal can be detected, so as to achieve the purpose of reducing the background and interference.
