Electrochemical cells have been in use for gas detection for over 50 years. In that time, many types of detection cells have been developed. A gas is a potential candidate for electrochemical detection if it oxidizes or reduces at standard conditions and if a suitable membrane material exists to control diffusion.
For gases that meet these criteria, electrochemical cell technology offers inherently linear response and good precision at low concentrations. Linearity allows calibration with only two points. If the atmosphere is used as one point, only one supplied calibration gas is required to calibrate an electrochemical gas detector.
Each gas requires a cell tuned to that specific gas. However, since the outputs of the cells are similar, the basic electronics, data management, and transmission process can be supported by a common modular platform.
Analytical Technology has used this characteristic of electrochemical detection to develop a common platform, the F12 Toxic Gas Transmitter. This fixed point gas monitor platform supports the detection of oxygen and over thirty different gases, many in multiple ranges.
In facilities that have multiple gas detection needs, the use of a common platform has financial, operational, and reliability advantages. Installation is simplified because installing the platform in multiple instances is simply a repetition of the first installation. Instrument technicians also have a single device to learn, simplifying their job and improving their speed and performance.
Electrochemical cell detection is a proven technology. The Toxic Gas Transmitter puts this reliable technology into a practical and easy to use system that is capable of detecting a variety of gases using a common platform.
