PEN2 is our small, fast and robust identification system for gases and gas mixtures. The detection of the gases is performed with an array of gas sensors.

Single compounds or mixtures of gases can be identified after a training step by using the pattern generated by the sensors. The instrument provides a fast and easy answer like "god" or "bad", "yes" or "no" depending on the needs of the user.

Because of its particular sampling strategy our detector can be operated in the laboratory, or in mobile applications in the environment as well as online for process control applications.

EDU is a fully automatic sampling and desorption device. The system works as a stand-alone unit performing continuos cycles with the steps sampling, thermal desorption, injection, cleaning and cooling automatically. With the adsoption technique compounds of interest can be adsorbed on the tubes, but also a pre-separation of the compounds of interest during sampling is possible.

Depending on the target substance and the sampling time the detection limit can be improved by some orders of magnitude. Especially when working with an electronic nose as a detector it has the advantage that disturbing or non smelling compounds like water, methane or ethanol are not trapped, permitting a better correlation to human smell perception.

	Increased Selectivity
	Automatic Cycles from Sampling to Thermal Desorption
	Easy and Fast Exchange of Sampling Tubes
	Stand-alone Unit
	Programmable Device
