We get some FAQs here in the analytical lab…one recurring question here at Gateway is “Why did/didn’t you do Raman?” During foreign particulate matter investigations, the use of spectroscopy is pretty common. Spectroscopy allows us to study the way a material interacts with energy, in order to identify a material. Sometimes, a scientist may use […]

The Gateway Analytical lab currently houses a Bruker Optics SENTERRA Raman Microscope with green and red lasers for spectral data collection. A high performance Raman microscope spectrometer, this system contains an internal continuous calibration mechanism that ensures better than 0.1cm-1 accuracy and precision without the need for external standard calibrations. The system also offers high performance confocal depth profiling via FlexFocusTM, Automatic Fluorescence Rejection (AFR) using shifted excitation Raman difference spectroscopy and an open architecture for the study of larger samples with high lateral resolution.

Fourier transform infrared spectroscopy (FTIR), a term originating from the mathematical algorithm required to convert the raw data acquired, is an analytical technique used to obtain an infrared spectrum of solids, liquids or gases. Simultaneously collecting spectral data in a wide spectral range, FTIR is used to rapidly evaluate and identify materials, contaminants, adhesive performance and quality control screening.

For decades, industries such as materials science, forensics and environmental science have used scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS) as a routine analytical method. The development of automated particle analysis quickly expanded this method’s application, laying the foundation for fast, efficient analysis of microscopic particulate. Today’s automated SEM/EDS systems are routinely used for forensic gunshot residue analysis, environmental particulate characterization, wear debris testing, particle sizing and identification of raw materials in industrial and pharmaceutical products, inclusion testing, etc.
