Frequently Asked Questions (FAQ)
Q
What technology does this Raman detector use to achieve compact size and high signal efficiency?
The device utilizes Transmission Body Phase Grating (VPG) technology combined with spatial direct coupling and confocal technology. This combination allows the instrument to maintain a small and lightweight form factor while still achieving large-flux Raman signal acquisition and highly accurate substance identification.
Q
How 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, with a standard detection time of ≤ 5 seconds (tested with pure ethanol). This makes it approximately 10 times faster than other Raman detection devices currently available on the market.
Q
Can this device detect substances through packaging or containers without opening them?
Yes. The device features penetration detection capability, allowing it to detect substances through white paper, envelopes, plastic bottles, brown glass bottles, and other semi-transparent materials — without any need to open or sample directly from the container.
Q
Is this device suitable for outdoor or harsh environment use?
Absolutely. The device is built to military design standards with an IP67 protection rating, making it waterproof, dustproof, and shockproof. It operates reliably across an operating temperature range of -20℃ to 50℃, and meets the requirements of GJB1751A-2007 General Specification for Poison Alarms for shockproof and anti-fall performance.
Q
How large is the substance database, and can it be expanded?
The device comes with a material spectrum database that can accommodate more than 10,000 substance types. The database is expandable based on user needs, allowing organizations to add specific chemical agents, explosives, or other substances relevant to their application scenarios.
Q
Does the device support connectivity with other systems or computers?
Yes. The device is equipped with both an RS485 communication interface and a USB interface, enabling seamless integration with external systems, computers, or data management platforms. It also features a 3.5-inch LCD screen for on-device result viewing and is powered by a rechargeable 18650 lithium battery supporting over 8 hours of continuous use.
