Chapter 1: Techniques

Aquascan Techniques for Real-Time VOC Monitoring

Aquascan systems utilize a combination of advanced analytical techniques to achieve real-time monitoring of volatile organic compounds (VOCs) in water. These techniques ensure accurate identification, quantification, and continuous analysis of VOCs, providing valuable insights into water quality.

1.1. Gas Chromatography (GC):

Gas chromatography is a fundamental technique employed in Aquascan systems. It separates individual VOCs based on their volatility and interaction with a stationary phase within a column. The separated VOCs are then detected and quantified by a suitable detector, providing a unique signature for each compound.

1.2. Mass Spectrometry (MS):

Mass spectrometry complements GC by providing precise molecular weight information for each separated VOC. MS bombards the separated molecules with electrons, creating ions that are then sorted by their mass-to-charge ratio. This information further aids in identifying and quantifying specific VOCs with high sensitivity.

1.3. Automated Sampling and Data Processing:

Aquascan systems integrate automated sampling and data processing for efficient operation. Continuous water samples are automatically collected and analyzed, eliminating manual intervention and ensuring consistent data flow. The collected data is processed in real-time, generating alerts and reports based on predefined thresholds and parameters.

1.4. Other Techniques:

In addition to GC-MS, other techniques may be incorporated into Aquascan systems depending on the specific application and requirements. These include:

• Headspace Analysis: This technique captures VOCs from the headspace of water samples, simplifying their analysis.
• Purge and Trap: This method extracts VOCs from water using a purge gas and traps them for subsequent GC-MS analysis.
• Spectrophotometry: This method measures the absorbance of specific wavelengths of light, providing information about certain VOCs present in water.

Conclusion:

The combination of these advanced analytical techniques enables Aquascan systems to deliver accurate, continuous, and real-time monitoring of VOCs in water. This empowers water treatment facilities to proactively address potential contamination, ensuring cleaner and safer water for all.
