Portable Raman Spectrometer: Rapid Detection of Illegal Additives and Pesticides

Portable Raman spectrometer, as a new generation of intelligent detection equipment, provides a solution for screening illegal food additives through the integration of laser Raman spectroscopy and network data verification technology. Combined with enhancing reagents and pretreatment equipment, it can complete the entire process from sample preparation to result determination within minutes. It is particularly suitable for grassroots law enforcement and market sampling, achieving efficient supervision with "instant testing and immediate results".

1.Technical Advantages: Raman Spectroscopy Enables Accurate Detection

The portable Raman spectrometer uses laser Raman fingerprint spectroscopy analysis technology. By exciting sample molecular vibrations with a laser to generate characteristic spectra and comparing them with a cloud-based spectral library, it can accurately identify over 200 types of illegal additives and pesticide residues such as melamine and Sudan Red. Its spectral resolution can reach up to 4 cm⁻¹, with stability controlled within 2%. Even when dealing with complex matrix samples, it ensures the repeatability and reliability of detection results.

2.Scenario Coverage: Safety Protection from Farm to Table

The portable Raman spectrometer comes with dual software systems, Uspectral Plus and FOODSAFE, supporting three core functions: data detection, public opinion tracking, and limit standard comparison. For example, during sampling inspections in agricultural markets, law enforcement officers can quickly complete sample pretreatment through the large touchscreen interface and obtain data on pesticide and veterinary drug residues such as thiabendazole and malachite green within 10 minutes. In the catering sector, the device can simultaneously detect abused additives like sodium thiocyanate and sibutramine and output compliant reports using the built-in printer. Additionally, the software module can capture hot topics in food safety in real time, assisting regulatory decision-making.

3.Hardware Configuration: Balancing Portability and Professionalism

The portable Raman spectrometer measures only 479×387×155 mm and weighs 11 kg, with a one-hand carry design that meets outdoor law enforcement needs. It is equipped with a 785 nm low-power laser with a lifespan of over 10,000 hours and adjustable output power of 0-500 mW, making it suitable for detecting samples of different concentrations. A 5-hour battery life and USB 2.0 data transfer interface ensure worry-free prolonged field operation. The spectral range covers 200-3000 cm⁻¹, with integration time adjustable from 1 ms to 65 s, enabling both the capture of characteristic peaks of trace harmful substances and the avoidance of fluorescence interference.

The portable Raman spectrometer's open customization feature for detection projects allows for rapid expansion of the spectral library for regional risk substances, such as specialized screenings for gutter oil identification and seasoning adulteration. From the laboratory to the law enforcement scene, from sampling and sending for inspection to instant determination, this device simplifies the detection process and improves detection efficiency.
