Raman spectroscopy is a spectroscopy technique which can be used for rapid identifica-
tions of chemicals. The Raman effect occurs when a light (f.eg. from a laser) interacts with
the sample molecules. Light scattered from the molecules gives rise to a spectrum that typ-
ically consists of a series sharp lines and can be considered to constitutes molecules finger-
print of the analyzed substance.
The Arx instrument is a hand-held Raman spectrometer which can be used without for-
mal training in spectroscopy to obtain chemical identity of substances as well as verify the
quality of known substances in order to be able to make immediate action decisions in the
field. The Arx is a standalone instrument that operates without need for other components.
However, generating measurement reports, user management and management of user
defined libraries is performed using the PC software Chemdash. The use of the Chemdash
software requires basic PC knowledge. Laser training is needed for all users since the in-
strument includes class 3B invisible laser.
This manual describes the basic functions of the instrument. Functions may be different
depending on the hardware and/ or software version in the device. The manual covers Arx
devices with embedded software functionality version 5.5.0 or later.
The software version is shown in the “About” window. The serial number of the instrument
is printed on the back of the instrument (S/N) and is also shown in the “About” window for
software.
Please NOTE that you can access ChemDash 2.0 only if your instrument is running
software version 5.5.0 or later. If your instrument is running an older version, please
upgrade the firmware first by following the instructions in the Firmware Upgrade
Guide on serstech.com
