The was held at INGV of Palermo from 13 to 17 November 2017. 

Results

The first, still preliminary, data on the field measurements performed by using of GC equipment and two different laser-based instruments provide reliable and comparable results. 

Most of the participants are still carrying out laboratory measurements with their own instruments. The results will be later compared with those already obtained at INGV-Pa labs during the workshop.

An important issue raised during the analytical operations is the selection of appropriate mixing standards for the quantitative calibration of the instruments, which strongly depends on the type of sample (gas from the water column, gas from interface water table/atmosphere or atmospheric gases). This issue will be further discussed among the infrastructures and more comparative tests are planned.
