ChemScan: Utilizing Advanced Spectroscopic Techniques for Real-Time Analysis

ChemScan process analyzers leverage a combination of powerful spectroscopic techniques to provide continuous and accurate measurements of critical parameters in environmental and water treatment applications. These techniques, including Raman spectroscopy, Near-Infrared Spectroscopy (NIR), and X-ray Fluorescence (XRF), offer unique advantages and capabilities:

1. Raman Spectroscopy:

• Principle: Raman spectroscopy analyzes the unique vibrational patterns of molecules, allowing for identification and quantification of specific compounds. When a sample is irradiated with a laser beam, some of the light is scattered inelastically, resulting in a change in frequency. This frequency shift, known as the Raman shift, is characteristic of the molecule's structure and can be used for identification and quantification.
• Advantages: Non-destructive, provides detailed molecular information, suitable for various analytes, including organic and inorganic compounds.
• Applications in Environmental & Water Treatment: Monitoring chlorine residuals, dissolved organic carbon (DOC), pesticides, and other pollutants.

2. Near-Infrared Spectroscopy (NIR):

• Principle: NIR spectroscopy measures the absorption and reflection of near-infrared light by a sample. This technique exploits the overtones and combination bands of molecular vibrations in the near-infrared region.
• Advantages: Rapid analysis, high sensitivity, suitable for analyzing complex mixtures, non-destructive.
• Applications in Environmental & Water Treatment: Monitoring turbidity, pH, conductivity, and other parameters in drinking water and wastewater treatment.

3. X-ray Fluorescence (XRF):

• Principle: XRF involves bombarding a sample with X-rays, causing the atoms to emit secondary X-rays with characteristic energies that correspond to the elements present.
• Advantages: Provides elemental composition information, fast analysis, non-destructive.
• Applications in Environmental & Water Treatment: Measuring metal content in wastewater, monitoring soil and sediment contamination, and analyzing heavy metals in drinking water.
