Raman Spectroscopy

Field Portable to handheld, a Full Range of Raman Solutions

Raman spectroscopy, a molecular spectroscopy which is observed as inelastically scattered light, allows for the interrogation and identification of vibrational (phonon) states of molecules. As a result, Raman spectroscopy provides an invaluable analytical tool for molecular finger printing as well as monitoring changes in molecular bond structure (e.g. state changes and stresses & strains).

In comparison to other vibrational spectroscopy methods, such as FT-IR and NIR, Raman has several major advantages. These advantages stem from the fact that the Raman effect manifests itself in the light scattered off of a sample as opposed to the light absorbed by a sample. As a result, Raman spectroscopy requires little to no sample preparation and is insensitive to aqueous absorption bands. This property of Raman facilitates the measurement of solids, liquids, and gases not only directly, but also through transparent containers such as glass, quartz, and plastic.


Handheld Raman Spectrometers

The development of handheld Raman spectrometers has drastically changed the way the industry conducts quality control for incoming raw materials. Raman has always provided advantages over other methods in that it does not require sample pre-treatment or direct contact with the sample, and has the unique capability of being able to test a sample directly through a transparent packing material like glass or plastic. With the added benefit of portability, handheld Raman spectrometers considerably increase efficiency by eliminating the need for additional space and wet chemistry.

Additionally, the intuitive onboard software doesn’t require the user to have virtually any knowledge of analytical chemistry in order to use the instrument on a routine basis. You do not need a high level of operator expertise or exhaustive sample preparation procedures to use handheld Raman equipment in a production environment or for remote field applications.

B&W Tek is dedicated to providing you with the best handheld Raman solutions possible. The NanoRam is the first handheld Raman spectrometer of its class to feature laboratory grade performance and computer processing in the palm of your hand. This revolutionary tool is quickly becoming the industry standard for quality control, forensic analysis, and anti-counterfeiting. The NanoRam is the ideal solution for incoming material identification and verification, at-line sampling, final inspection, and counterfeit drug detection. By combining state of the art TE cooling and spectrum stabilized laser technology, the NanoRam is the most sensitive and repeatable handheld spectrometer ever designed to identify harmful and non-conforming materials.

LIBS - Laser induced breakdown spectroscopy

Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites samples. In principle, LIBS can analyse any matter regardless of its physical state, be it solid, liquid or gas. Because all elements emit light of characteristic frequencies when excited to sufficiently high temperatures, LIBS can (in principle) detect all elements, limited only by the power of the laser as well as the sensitivity and wavelength range of the spectrograph & detector.


NanoLIBS


The NanoLIBS is a state-of-the-art handheld Laser Induced Breakdown Spectroscopy instrument using elemental analysis for identification and investigation of raw materials such as ionic salts such as NaCl and KCl within a regulated environment.
