The SLS technology is especially effective at assessing
downstream gas quality as gases from different sources, including
biogas, shale gas and substitute natural gas, are added to the gas
distribution stream.

Gas chromatography is used to analyze the quality and chemical
composition of natural gas and is a core component of Smart Grid
solutions for natural gas. Gas chromatography also has multiple
laboratory applications.

“The addition of this innovative gas chromatography technology
from SLS further strengthens Elster’s position in the emerging
biogas and shale gas markets. These sources of gas require precise
volume and quality measurement as they are mixed in with more
traditional natural gas sources,” said Michael Calovini, executive
vice president of Elster’s international gas business.  

Elster plans to integrate the technology from SLS into its
existing gas measurement and quality solutions at its gas quality
competence center in Dortmund, Germany. The new technology will
extend Elster’s existing gas quality portfolio of fast sensor
systems (gaslab Q1) and high-end process gas chromatographs (EnCal
3000) with an additional series of smart micro-gas chromatographs
for energy measurement applications.
