Optical Sensor for Unknown Gas Detection

Gas sensors are usually engineered to detect a specific molecule in one of many potential categories: toxic gases, combustible gases, VOCs. A number of technologies, such as infrared, photoionization, catalytic and electrochemical, are used to test for differing molecular species. Each method has different specifications for resolution, sensitivity, temperature, and humidity range. Gas sensors are most useful with flexibility in gases detected and high sensitivity.
Patent Abstract: 
LLNL researchers have combined Raman and infrared (IR) spectroscopy methods in a single device. The sensor is able to detect, identify, and quantify a range of unknown gases.
