Portable Raman spectrometer with docking station

Type of infrastructure:

Portable Raman spectrometer with docking station.

Technical description/model and performance:

The Bruker BRAVO portable Raman spectrometer features a class 1 NIR diode laser, operating at 6 different lines with a patented
fluorescence mitigation (SSE). It can be used connected to a computer or on its own. It is lightweight (2.5 kg) and portable, with a convenient touch screen. Data and reports can be transferred wirelessly or up-/downloaded via the docking station. Battery life is ca. 4 hours, but there is an additional battery and a charger.
Measuring tips are changeable for point-shoot mode and vials.

Field of application:

The instrument is used for the chemical compositional analysis of a wide range of bulk samples, from solids to liquids or even gases. It is portable and thus can be taken to samples that require special handling and/or cannot leave their location (fume hoods, sterile environments, laboratories for genetically modified organisms). It uses a class 1 laser, and thus can be used without special eyewear. It is fast (typical measurements take 1-5 m

inutes) and sensitive. Due to built-in fluorescence mitigation (SSE) and low laser power, even dark, fluorescing and weak scattering samples can be analysed.

Basic Mode of Operation:

The instrument is extremely easy to operate, essentially "point and shoot": place the sample (either natively or in a transparent container, such as a glass vial) in front of the instrument at the beam exit. Specify file name and recording conditions (such as spectral range, time of exposure), and collect a spectrum. White light can disturb the results and thus it is advantageous to block white light entering the beam path (either by forming a good contact between the beam exit and the sample, or covering the sample or measuring in dark).


The instrument is placed in the Chemistry building, 1st floor (basement), KB.C1 (B1.09.01).

Access to the Instrumentation:

The instrument can be operated by anyone with a valid license. Courses for acquiring such a license are held regularly (twice a year), see: http://www.kbc.umu.se/english/visp/visp-courses/
Booking of the instruments can be done online with a valid license at the following link:

Other Information:

The instrument is portable and thus can be taken from the laboratory.
