Research of the Rapid Embedded Quantitative Test System For Antibiotics

摘要

This system tests for antibiotic residues quantitatively. First,it used a gold-colloid strip to detect the antibiotic on which two lines would appear after about 12 minutes. One is standard line and the other is test line. The color of the test line would be different as the antibiotic concentration was changed. Then it captured the two lines information as a bit map by CMOS image sensor and sent it to S3C2410 processor based on ARM 920T core. At last it called the application to analyze the data and gave the exact antibiotic concentration value. The process takes less than 15 minutes.And the precision can be 0.5ppb.
