Frequently Asked Questions
QWhat technology does this Raman detector use to achieve its compact size?
The device utilizes Transmission Body Phase Grating (VPG), spatial direct coupling, and confocal technology. This combination enables a small volume design while maintaining large flux Raman signal acquisition, resulting in a lightweight unit of only 694g.
QHow fast is the detection speed compared to other Raman devices on the market?
The device can produce detection results in as little as 3 seconds, making its detection speed approximately 10 times faster than other Raman detectors currently available on the market. The specified benchmark is ≤5 seconds using pure ethanol as a reference sample.
QCan this device detect substances through packaging materials?
Yes. The device supports penetration detection, allowing it to detect substances through white paper, envelopes, plastic bottles, brown glass bottles, and other micro-transparent materials — without requiring the sample to be opened or extracted.
QWhat is the accuracy rate and how large is the substance database?
The device achieves an accuracy rate of more than 99%. Its built-in material spectrum database supports over 10,000 substance types, and can be further expanded to meet specific user requirements and deployment scenarios.
QIs the device suitable for field use in harsh environments?
Absolutely. The device is rated IP67, making it waterproof and dustproof. It also meets the shockproof and anti-fall requirements of GJB1751A-2007 (General Specification for Poison Alarms), and operates reliably across a wide temperature range of -20℃ to 50℃.
QHow long can the device operate on a single battery charge?
The device is powered by a rechargeable 18650 lithium battery and supports continuous operation for no less than 8 hours, with a measurement capacity of at least 25 detections per hour under standard ethanol verification testing conditions.
