High-Quality Raman Spectrometers
BroLight's Raman spectroscopy instruments enable non-destructive, non-contact analysis of chemical and biological samples with no pretreatme
Raman spectroscopy serves as an ideal analytical tool for investigating biological specimens and chemical compounds in aqueous solutions. Raman spectroscopy produces clear and sharp spectral peaks, making it particularly suitable for quantitative analysis, database matching, and qualitative studies through differential analysis. With a broad spectral range of up to 4000 cm⁻¹, Raman spectroscopy enables the analysis of both organic and inorganic substances. Furthermore, Raman measurements require no sample pretreatment and offer a range of advantages—such as non-contact operation, non-destructiveness, real-time capability, rapid detection, and the ability to analyze materials directly through transparent packaging.
What is a Raman spectrometer?
A Raman spectrometer is an analytical instrument among photonics instruments used to measure the Rayleigh scattering effect, which is a type of light scattering that occurs when light interacts with matter. Raman spectrometers 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 machine consists of three components: the laser, the spectrometer itself, and the sampling interface. A Raman laser has a narrow linewidth, small form factor, low power consumption, and an extremely stable power and exciting wavelength output. The precision-engineered Raman 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.
How Does a Raman Spectrometer Work?
A Brolight Raman spectrometer operates by directing a laser beam onto the sample. The resulting Raman-scattered light is collected and channeled into the Raman spectrometer, where it is dispersed into its constituent wavelengths. A highly sensitive detector then captures this signal. The final output is a Raman spectrum—a plot of intensity versus wavelength shift—that reveals unique molecular vibrational fingerprints, enabling precise substance identification and the study of molecular interactions.
Raman spectroscopy is a "fingerprint spectrum" of molecular vibrations. Different molecules of substances have different vibrational frequencies, hence it is often used as an important basis for substance identification.
In Raman spectroscopy tests, there is no need to touch the samples, which makes it very convenient for testing and analysis of both liquid and solid samples. During the test, BRM-760X series is selected as the incident light source. According to the requirements of detection sensitivity, BIM-6002A or BIM-6703 series spectrometers are chosen to collect spectra. The light conduction uses SIM-6131 series Raman probes, and the corresponding test accessories are selected for liquid and solid samples respectively.
