Direct & quick on-site material identification overcomes all challenging field conditions.
GMD is a portable Raman spectroscope that specialises in quick on-site material identification, particularly designed to inspect samples stored in different conditions. No matter whether the samples are stored in a vial / cuvette, on a slide / SERS chip, naked or in a plastic bag, the materials could be identified directly and rapidly.
On a slide / SERS chip
In a vial / cuvette
A gemstone / diamond
In addition to a variety of sample holders, the laser head could point downwards. With an objective attached and the use of a sample stage beneath, the GMD could be used for measurements with higher accuracy, suitable for laboratory study.
* Vertically downwards with an objective
The vertical head could also be switched to a horizontal head. With the flexibility of attaching different sample holders and objective, the GMD is able to overcome diversified environmental restrictions.
* Horizontal laser head with a vial holder
With an extended arm, a horizontal head and an objective, GMD is ideal for the authentication of large historical artworks where no samples could be collected from the subjects.
* Custom-made extension arm
These features enable GMD to easily identify gemstones, works of arts, minerals, pharmaceuticals, illicit drugs, food, fuel and many other industrial raw materials, making GMD an ideal solution for challenging field application in addition to laboratory study.
GMDX is a custom-made portable Raman microscope that utilises a high resolution digital camera with a high sensitivity image sensor. The XYZ 3-axis manual sample stage ensures accurate positioning with the aid of the digital image. This all-in-one compact system allows measurements to be carried out with great flexibility and mobility.
In addition to the laser safety cover and laser temperature stabiliser, the enclosed chamber also reduces environmental noises. The sample stage could be controlled from outside, making GMDX an ideal alternative for conventional bulky Raman microscope in terms of field application, including chemical, medical, pharmaceutical, botanical, biological, forensic and mineral research.
