Radiation food and drug rapid detection device

PPSL-18Radiation food and drug rapid detection devicebelong toLight stimulated luminescence（PSL system，also known asLuminescent system,Composed of a pulse excitation light source (infrared excitation light source), a sample chamber, a detection probe, a photon counting system, and a control unit, it is used for rapid identification of whether food and drugs have been irradiated. Widely used for rapid screening of traditional Chinese medicine decoction pieces, solid preparations containing raw powder, spices, seasonings, etc., it can effectively identify samples treated with ionizing radiation (irradiation) at a dose of 1kGy or above. Comply with the Guiding Principles for Photoluminescent Identification of Irradiated Traditional Chinese Medicine in 2025 National Drug Standard "Guiding Principles for Photoluminescent Identification of Irradiated Traditional Chinese Medicine"

As an efficient and economical method for microbial sterilization, inhibition of plant germination, and extension of food shelf life, irradiation technology has been widely used in fields such as food and medicine. However, just like genetically modified foods, the effects of irradiated food and drugs on the human body are still unknown. For the long-term consideration of human health and safety, developed countries such as Europe and America have long strengthened their supervision of irradiated food and drugs. In China, with the increasing public awareness of food safety and the government's attention, food and drug regulatory authorities have also begun to strengthen their supervision of irradiated food and drugs to prevent irreversible consequences caused by the abuse of irradiation technology in the future.

Chinese medicinal herbs, spices, etc. usually contain or carry minerals (inorganic substances, silicates, etc.). When exposed to ionizing radiation (irradiation), these minerals store energy through their structural voids. When stimulated by excitation light, these stored energies will be released in the form of photons.OslIdentification method is a method of identifying whether traditional Chinese medicine decoction pieces and solid preparations containing raw powder have been subjected to ionizing radiation (irradiation) based on the number of photons released.

PPSL-18Radiation food and drug rapid detection deviceadoptdiameter50mmPi'sSample dishThe required sample quantity is extremely small,Single sample testing time only takes 60 seconds.

The PPSL-18 is designed to be compact and small in size, requiring only one data cable to connect to a computer for operation. All testing processes, except for sample collection and placement, are completed by software operation.
