Abstract: Hydrogen Sulfide detection and measurements has evolved exponentially over the past twenty years. One of the early methods was spot measurement of the gas stream using the so called Dragger tubes. These tubes are made with different scales for different concentrations by companies such as Dragger and Sensodyne. This method was quick and fairly inexpensive. The main problems encountered using this method are the lack of accuracy and not having continuous monitoring to the gas stream. Furthermore, this procedure requires a dedicated person to perform this measurement in a regular basis. In the Eighties many company started to use the microprocessor based system to provide a continuous and accurate detection and measurement of the HS level in the monitored gas stream. Since then the use of microprocessor has evolved exponentially with new technology emerging in an incredible speed.The methods of detection vary significantly depending upon the media used as the sensing element. The most common methods are the thin film Solid-state Sensor, electro-chemical sensor, lead acetate tape, and infrared analysis.
