PhD 2 in Environmental & Water Treatment: A New Era of Gas Detection

Chapter 1: Techniques

Traditionally, gas detection in environmental and water treatment primarily relied on **single-gas detectors**. These devices were limited in functionality and often cumbersome to operate. They typically employed techniques like:

• Electrochemical Sensors: Measure the current produced by a chemical reaction with the target gas.
• Infrared Sensors: Detect gases by measuring the absorption of infrared radiation.
• Catalytic Bead Sensors: Utilize a bead coated with a catalyst that changes resistance when exposed to specific gases.

**PhD 2 technology** introduces a paradigm shift by integrating **multiple gas sensing techniques** within a single, portable device. These advancements include:

• Electrochemical Array: Multiple electrochemical sensors are integrated to detect a wider range of gases simultaneously.
• Miniaturized Infrared Spectrometry: Advanced micro-spectrometers enable the analysis of infrared spectra, allowing for the identification and quantification of multiple gases.
• Metal Oxide Semiconductor (MOS) Sensors: These sensors react to the presence of specific gases by changing their electrical conductivity.

These techniques, when combined, enable **real-time, multi-gas detection** and enhance the accuracy, sensitivity, and versatility of gas monitoring in environmental and water treatment applications.
