SAFE EthanTest

Simple and automatic analysis of gas

In practise, there will always be locations where gas is emanated, making a gas analysis necessary. It should be guaranteed from the analysis that the located gas is natural gas and not biogas (fermentation gas or marsh gas). 
The differentiation occurs by the evidence of ethane (C2H6) in gas. Ethane is only in natural gas and therefore is suitable as a clear indicator for evidence. The SAFE EthanTest contains a chromatographic separating column in which the gas sample is broken down and is let out for a delayed period of time. The small-molecular methane is the first to reach the sensor and is displayed. Ethane then follows after a certain interval, if it is natural gas. This technology has already been on the market for years. However, the operation was rather complicated and only very experienced personnel could make clear statements. But that is the end of that! 

The main focus of the development was on reliable analysis and completely trouble-free use. The user does not need to mix a sample of a suitable concentration nor evaluate the measurement results. Even measurement inaccuracy at low service temperatures could be eliminated by tempering and temperature monitoring of the chromatographic column.  

In practise, this means: 

  • Taking the service box to the measurement site
  • Activate device and connect sensor
  • Feed sensor into sensor hole and start analysis at the touch of a button
  • SAFE absorbs a gas sample and displays its concentration in vol.%
  • The gas sample passes through the chromatographic column and the display of methane and ethane (if applicable) takes place
  • The results display shows the clear results alongside the measured gas concentrations
  • A results protocol is printed out and in addition, the measurement is saved in the memory
  • Robust complete system in a service box
  • Fully automatic sampling and analysis
  • Reliable measurement result within five minutes
  • Automatic valudation by the measurement system
  • Documentation of the measurement with the built-in printer
  • Data memory and infrared interface to transfer all measurement data to the PC
