Infrared Spectroscopy (IR) Analysis

At CD BioSciences, we are at the forefront of leveraging the power of Infrared Spectroscopy (IR) to provide comprehensive environment-friendly materials performance analysis services. IR spectroscopy is a versatile analytical technique that utilizes the infrared region of the electromagnetic spectrum, ranging from 0.78 μm to 1000 μm in wavelength, to study the composition and properties of a wide range of materials.

What is Infrared Spectroscopy (IR)?

Infrared radiation interacts with the molecular bonds within a sample, causing them to vibrate and absorb energy at specific wavelengths. This unique absorption pattern serves as a "fingerprint" for the sample, enabling the identification and quantification of its chemical constituents. By analyzing these IR absorption spectra, our team of experts at CD BioSciences can gain valuable insights into the structure, composition, and behavior of various environmental materials.

Infrared Spectroscopy (IR) in Environment-friendly Materials Performance Analysis

• Sub-boiling Distillation
  The sub-boiling distillation method, pioneered by researchers at the National Institute of Standards and Technology (NIST), utilizes IR radiation to gently evaporate the surface of liquids, such as analytical reagents, without the formation of aerosol particles. This prevents contamination and produces highly pure compounds for use in various analytical procedures.
• IR Drying Techniques
  IR drying techniques directly transfer heat from IR sources to the sample, enabling rapid and uniform drying without the need for hot air or steam. This approach offers significant advantages over traditional drying methods, including reduced energy consumption, precise temperature control, and the prevention of sample damage or overheating.
• IR Combustion and Volatilization
  Researchers have developed IR-based combustion and volatilization methods to transform solid and liquid samples into gaseous forms, improving the accuracy and sensitivity of trace element analysis through techniques like atomic spectrometry. This streamlined sample preparation workflow minimizes the environmental impact of the analytical process.
• Focused Infrared Lightwave Ashing (FILA) and Automated Focused Infrared Microashing (AFIA)
  These state-of-the-art IR-based ashing techniques utilize the rapid and uniform heating capabilities of infrared radiation to completely digest organic matrices in environmental samples. This eco-friendly approach reduces waste generation and enhances the quality of the resulting sample solutions, facilitating efficient multi-element analysis.
• IR-assisted Wet Digestion
  By harnessing the intense heating power of IR lamps, researchers can accelerate the wet digestion of various environmental matrices, such as soil, sediment, and biological materials. This IR-assisted approach significantly reduces the time and resources required for sample preparation while maintaining the integrity of the analytes.
