Abstract
A scanning analyzer unit comprises a scanner device, a signal amplifier, an analog/digital converter, a driver device, a controller device, a computing unit, and a RS-232 interface. After chemical, biological, or chemi-enzymatic reaction, a resulting color change of a testing support through reacted multi-chromogens therein is quantified by means of the scanning analyzer unit. Via the sensitivity differences of the multi-chromogens at a fixed wavelength of the scan, multi-analyte concentrations of wide range variations in one sample can be simultaneously assayed.
Claims4
A scanning analyzer unit, for analyzing a sample in a testing support, the scanning analyzer unit comprising:
- a scanner device, for scanning the testing support suitable for supporting a reaction of analytes in the sample to achieve a color separation, wherein the scanner device outputs a test signal corresponding to concentrations of the analytes in response to scanning of the testing support after the reaction of the analytes, and wherein the scanner device comprises a light emission diode (LED) array;
- a signal amplifier coupled to the scanner device to amplify the test signal;
- an analog/digital converter coupled to the signal amplifier, wherein the analog/digital converter converts the amplified test signal into a digital test signal;
- a computing unit, coupled to the analog/digital converter, for receiving and analyzing the digital test signal to output a control signal and to obtain concentration values of the analytes;
- a controller device, coupled to the computing unit, for receiving the control signal and outputting a driver signal according to the control signal;
- and
- a stepping motor, coupled to the controller device and the scanner device, for receiving the driver signal and driving the scanner device to measure the concentrations of the analytes.
