Raman spectrometer – FAQs

What is a Raman spectrometer?

A Raman spectrometer is an analytical instrument used to measure the Rayleigh scattering effect, which is a type of light scattering that occurs when light interacts with matter. Raman analyzers are powerful tools for non-destructive analysis and characterization of a wide range of materials, providing valuable insights into their molecular composition and structure.

A Raman spectroscopy device consists of three components: the laser, the spectrometer itself, and the sampling interface. In a Raman spectrometer from Metrohm, all three components are developed and manufactured by Metrohm Spectro.

A Raman laser has a narrow linewidth, small form factor, low power consumption, and an extremely stable power and exciting wavelength output. The spectrometer is characterized by a high resolution, low noise, small form factor, and low power consumption. The sampling interface allows for precise, easy, and safe sampling. Metrohm offers various sampling interfaces and attachments to automate sampling in any situation from trace detection to through container analysis to data collection from across the room.

How does a Raman spectrometer work?

MIRA XTR DS, Raman spectroscopy, defense and security, first responders, no-contact testing, handheld Raman, narcotics, illicit drugs, Contact Ball Probe

The laser beam of the Raman analyzer is typically directed onto the sample, and the Raman scattered light is collected and directed into the spectrometer. The spectrometer disperses the scattered light into its different wavelengths, which are then detected by a sensitive detector.

The resulting Raman spectrum, which represents the intensity of scattered light at different wavelengths, provides information about the molecular vibrations and can be used to identify substances or study molecular interactions.

What is a Raman spectrometer used for?

Handheld Raman spectroscopy devices for Raman applications, e.g., defense and security

Raman spectrometers are used for identifying unknown materials and verifying or quantifying known materials. Raman spectroscopy is a non-destructive analysis technique that allows for fast and safe analysis, as no sample preparation is needed and, in some cases, samples can even be analyzed in their original packaging.

Applications of Raman spectroscopy include raw material verification, quality control of incoming goods, identification and analysis of active pharmaceutical ingredients (APIs), additives and excipients, and identification of illicit or counterfeit substances such as drugs.

What is the difference between handheld and laboratory Raman systems?

Handheld Raman systems are small, lightweight, easy-to-use, and require little to no training. Handheld Raman systems are capable of fast analysis and identification of unknowns in the field.

Laboratory Raman systems offer a higher resolution and sensitivity compared to handheld Raman systems. With the higher sensitivity of benchtop Raman systems, it is also possible to quantify substances down to low concentrations, while handheld Raman systems are often used to fulfill identification and qualification needs.
