Vibration and X-Ray Spectroscopy Related Facilities

Alfa Chemistry offers a variety of modern spectrometers to help you with your groundbreaking study. Infrared spectroscopy equipment, Raman spectroscopy instruments, and X-ray and ultraviolet photoelectron spectroscopy instruments are among the professional tools and sample accessories in our analysis laboratory.

Infrared Spectroscopy

The sample is bombarded with polychromatic light in infrared spectroscopy, and photons are absorbed when the frequency (energy) of the absorbed light matches the energy required for a specific bond to vibrate within the sample. The molecule dipole moment must change during the vibration process for the vibration to have infrared activity. The following are some of our infrared spectroscopy facilities:

• Bruker Tensor 27 FTIR with HYPERION II Microscope
• VERTEX 80v FT-IR Spectrometers
• SNOM Microscopele
• Bruker MPA Near Infrared Spectrometer

Raman Spectroscopy

The sample is bombarded with monochromatic light in Raman spectroscopy. The scattering of photons can be inelastic or elastic. During this interaction, inelastic scattered light (Raman scattering) loses or acquires energy, and the released photons include information about the sample's molecular structure. Rayleigh scattering occurs when elastic dispersed light has the same energy as the incident laser. Because Raman scatters just one out of every million photons, modern Raman equipment are intended to filter out Rayleigh light. The polarizability of the electron cloud around the molecule must vary when the molecule vibrates, which means the form, size, or orientation of the electron cloud surrounding the molecule must change.

The following are some of our Raman spectroscopy facilities:

• Renishaw Raman inVia Reflex and Bruker Innova AFM
• Bruker MultiRAM FT-Raman Spectrometer
• Renishaw RA816 Bioanalyzer

X-Ray and Ultraviolet Photoelectron Spectroscopy

The binding energy of a material, which is a property of chemical structure and molecular bonding, is measured using photoelectron (or light emission) spectroscopy. Surface characteristics are measured using X-ray (XPS) or ultraviolet (UPS), which is a very sensitive technology.

The following are some of our X-ray and UV photoelectron spectroscopy facilities:

• Thermo Scientific K-Alpha +XPS/UPS System
• Malvern Panalytical Portable XRF Analyzer
• Bruker Tracer 5i XRF Spectrometer
• Bruker ARTAX800 µ-XRF Spectrometer

Portable Instruments

When the location, size, or fragility of the sample cannot be used for laboratory analysis, Alfa Chemistry's portable analysis tools can support on-site analysis. The following instruments are available for use with our portable instrumentation:

• Bruker ALPHA Portable FTIR Spectrometer
• Bruker BRAVO Handheld Raman Spectrometer
• Enwave EZRaman Portable Raman Spectrometer
• Viavi MicroNIR Field Handheld NIR Spectrometer
