Problems solved by technology

However, few studies have been reported with the aim of simplifying sample handling
Sample processing is an essential and important part of electrochemical detection. When detecting some common substances, the operation is cumbersome and time-consuming, and sometimes takes up most of the entire detection process, and the technical requirements for operators are also relatively high.
Although there are related commercial kits that can achieve rapid preparation for this type of analyte, multi-step pipetting and mixing operations are still inevitable

Abstract

The invention relates to the technical field of detection, in particular to a handheld suction type electrochemical detection device capable of processing a sample automatically. The handheld suction type electrochemical detection device comprises a handheld electrochemical detector, and the handheld electrochemical detector comprises a sampling mechanism and an electrochemical monitoring mechanism; the sampling mechanism comprises a sampling sucker and a liquid transferring device, and the sampling sucker comprises a reagent tank or a filter core; the electrochemical detection mechanism comprises an electrode and an electrochemical control device, and the electrode is arranged in the sampling sucker; the liquid transferring device and the electrochemical control device are integrated into a handheld shell; a connector is fixed to the shell, the connector is detachably connected with the sampling sucker, an electrode interface is fixed in the connector, and the electrode interface is connected with a detection port of the electrochemical control device; when the sampling sucker is connected with the connector, the electrode is connected with the electrode interface. By means of the sampling mechanism, the sample can be sucked in and exhausted out to be prepared, filtered and the like; thus, automatic treatment of the sample is achieved; by means of the electrochemical monitoring device, the sample can be electrochemically detected.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an electrochemical detection device. Background technique [0002] The electrochemical detector includes a detection electrode and an electrochemical control device, and the detection port of the electrochemical control device is connected with the detection electrode. The electrochemical control device controls the electrochemical reaction conditions, collects the current information at the electrodes, and realizes the collection and reading of detection data. [0003] Traditional electrochemical detection instruments are bulky and expensive, and detection can only be performed in laboratories. When testing outdoor samples, a series of cumbersome steps are required for sampling, transportation, storage, sample processing and testing. [0004] Nowadays, in the fields of environmental water pollution detection, soil pollution detection, crop pesticide residues, food safety det...
