At present, there are five major heavy metals that are highly toxic to the human body: lead, mercury, chromium, arsenic, and cadmium. These heavy metals cannot be decomposed in water, and when combined with other toxins in water, they can form more toxic organic or inorganic substances, which are even more toxic when consumed by humans. The GB2762-2017 food safety standard specifies the limits of heavy metals such as lead, cadmium, mercury, arsenic, and chromium in various types of food, including meat, grains, vegetables, fruits, aquatic products, and drinking water. The GB13078-2017 Feed Hygiene Standard also specifies the limits of arsenic and lead in feed and its raw materials.
At present, the detection of heavy metal content is mainly carried out using atomic absorption spectroscopy. Shanghai Xiongtu Biotechnology Co., Ltd. has launched a new generation of rapid heavy metal detection instrument based on electrochemical method, which can quickly, easily and accurately quantify the content of various heavy metal ions in grains, feed, food, traditional Chinese medicine materials, vegetables, and aquatic products. High detection sensitivity, wide linear range, good stability, wide adaptability, compact and portable instrument, beautiful appearance, and networked traceability., Applicable to food safety regulatory departments at all levels, as well as fields such as grain and feed processing.

Rapid quantitative detection product for heavy metals

Product introduction

1. Using the principle of anodic stripping voltammetry, detect sample varieties including raw grains, finished grains, miscellaneous grains, industrial grains, etc; It can detect not only finished grains such as rice and flour, raw grains such as brown rice and whole wheat, but also vegetable oil, drinking water, breeding fresh water, non dairy liquid drinks, beer, Baijiu, soy sauce and vinegar.
2. The heavy metal detection items in grain include lead and cadmium, which can be detected simultaneously in one test. The detection can be completed in 15 minutes, and the pre-treatment process does not require concentrated acid or heating digestion, making the operation very convenient.
3. Use screen printed electrodes, which can be used immediately without polishing or maintenance, and do not require electrode treatment or coating during testing; The instrument uses the Android system and is easy to operate.
4. The test results can be printed on site, and the data can be exported for analysis and recording purposes. It can also be expanded to test other food safety projects.
