Problems solved by technology

In the early days, due to the relatively backward semiconductor integration technology, the potentiostat was mainly composed of a large number of discrete components, which had shortcomings such as bulky, complex structure, and poor constant potential control, which limited its application range.
[0004] At present, domestic potentiostats used for laboratory electrochemical performance testing are not suitable for actual engineering field applications due to their large size, heavy weight and uneasy portability.
However, the existing potentiostats used in actual engineering applications have low measurement accuracy, large control errors, inconvenient operation, and low intelligence, which cannot meet the needs of on-site electrochemical testing.
Moreover, the existing detection technology for trace vitamins in food has disadvantages such as complex detection methods, long detection time, high detection cost, and difficulty in popularization, as well as single application of detection devices, which cannot meet actual needs such as food safety.

Abstract

The invention discloses a portable potentiostat application platform based on vitamin B detection and aims to overcome defects of low measurement precision and large control errors of an existing potentiostat. The portable potentiostat application platform is characterized in that a power module is connected with a power input end of a microcontroller module; a D / A (digital-to-analog) conversion module converts digital quantity of the microcontroller module into analog quantity and transmits the analog quantity to an operational amplifier detection module; an A / D (analog-to-digital) conversion module converts sampling data of the operational amplifier detection module into digital quantity from the analog quantity and transmits the digital quantity to the microcontroller module; pull-in of a relay unit module is controlled through switching of high and low levels of a PC port in the microcontroller module, so that the connection state of a working electrode of the operational amplifier detection module is controlled; a key display module sends set parameters to the microcontroller module for processing and displays data received from the microcontroller module; an RS485 transmission module is connected with the microcontroller module and transmits detected signals to a GPRS (general packet radio service) wireless communication module. The portable potentiostat application platform based on vitamin B detection can detect trace vitamin B and can be combined with an electrochemical impedance test system for application.

Description

technical field [0001] The invention belongs to the technical field of electrochemical detection, and relates to a portable potentiostat application platform based on vitamin B detection. It can accurately detect the content of trace elements (especially vitamin B) in food, and has strong self-designed functions, which can be combined with other detection systems. Background technique [0002] Vitamin B (VB) is an important biological redox coenzyme in cells, and it is a kind of nutrient necessary for the body to maintain its normal life. For the addition of vitamin B in food, especially in infants and breast milk foods, the added amount must be strictly controlled through detection, so it is necessary to find a simple, efficient and rapid detection method. Vitamin B analysis methods mainly include fluorescence analysis, high performance liquid chromatography, ultraviolet spectrophotometry and electrochemical analysis. The electrochemical analysis method is a kind of analy...
