High-Precision and Low-Cost Wireless 16-Channel Measurement System for Malachite Green Detection

Focusing on the issue of the malachite green traditional test methods such as large volume, high cost and high complex, this paper proposed a novel multi-channel electrochemical malachite green detection system. Specific recognition properties of malachite green DNA adapter is employed to realize accurate sensing of concentration of malachite green, which can achieve precise detection of malachite green concentration with low noise and high precision. The maximum measurement capability of multi-channel acquisition system is 16 samples in a batch. According to the experimental results, malachite green could be detected quantitatively in the range from 10(−3) μg/mL to 10 μg/mL, which performs well in the test of malachite green residues in aquatic product transportation.
