Protect food and drug safety, starting from heavy metal detection

 "toxic wolfberry" triggered hot debate

Recently, CCTV's in-depth report on the "poisoned wolfberry" incident has aroused wide concern in the society. According to reports, in Qinghai Golmud, Gansu Jingyuan and other main wolfberry producing areas, some merchants in order to improve the quality and appearance of wolfberry, illegal use of sodium metabisulfite for "color enhancement", and even direct use of industrial sulfur smoking, and sulfur contained in lead, arsenic, sulfur will cause serious damage to the human liver or kidney. As a representative of "medicine and food homology", wolfberry is widely used in food, beverage, health care products and other fields. And under the processing of some criminals, it looks like the grain is full, bright and red wolfberry, but it has a huge food safety risk.

The "toxic wolfberry" incident once again sounded the alarm of food and drug safety. Food safety is a major issue related to people's livelihood, directly related to people's health and life safety. Ailiben Technology has been committed to the detection of heavy metals in food and drugs for a long time, and the food and drug heavy metal detector developed by Aliben Technology provides a new solution for food detection, food safety and Chinese medicine quality control.

Technical principle

International Patent: "A device for Direct Analysis of solid ablations based on plasma jet", Application number: PCT/CN2018/120782PJ-AES is a high-performance spectral instrument for direct analysis of solid samples based on the principle of atomic emission spectroscopy. It has built-in self-developed plasma excitation source with high energy density, and the high-temperature plasma directly acts on the surface of the solid sample. The elements in the sample are vaporized and excited at high temperature, and corresponding characteristic spectral lines are generated during the process of de-excitation back to the ground state. The composition and content of the elements in the sample are obtained by analyzing the characteristic spectral lines.

Characteristic function

Excitation from adaptation

The excitation source intensity is automatically adjusted according to the sample type to obtain the best excitation effect.

Automatic adjustment function

Instrument startup self-test, to achieve the best detection state.

Instrument intelligent protection

The instrument has automatic warning function to prevent the damage of the instrument caused by unexpected situations.

Intelligent software system

One key operation to complete automatic sampling and analysis, can quickly identify abnormal samples.

user-defined

Users can customize elements and detection limits according to their own needs.

Product highlights

It takes only 3-5 minutes from sample preparation to detection.

The test results are accurate and comparable with the national standard method.

High sensitivity, the detection limit of Cd can reach 0.01ppm, breaking the bottleneck and limitation of the original solid sample direct analysis technology.

Solid injection eliminates the need for complex chemical pretreatment.

Within 90 seconds, the full spectrum signal in the preset band can be obtained simultaneously, covering most metals and some non-metallic elements.

It is an environmentally friendly green detection technology without chemical reagents such as acid and base

Application field

Grain detection

Rapid detection of heavy metal elements in rice, rice, wheat and other food crops.

Food safety

Rapid detection of heavy metal elements in food such as bacteria, vegetables and dairy products.

Chinese medicine quality control

Rapid detection of heavy metal elements in roots, stems and leaves of different Chinese herbs.

Environmental analysis

Rapid screening of soil heavy metal pollution.
