Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The Analytical Laboratory (AN) of the JET Active Gas Handling System (AGHS) is a central facility of the AGHS connected via small bore tubes to the other AGHS sub-systems. It offers various techniques such as gas chromatography, mass spectrometry, ionisation chambers, katharometers and calorimetry, to characterise the various gas samples. The detection ranges of the gas chromatograph for the six hydrogen molecules, helium, nitrogen and oxygen are from about 100ppm to 100% and for methane, higher hydrocarbons, CO and CO2 from about 10ppm to 100% with a thermal conductivity detector and a flame ionisation detector, respectively. Similar detection ranges can be achieved with the quadrupole and omegatron mass spectrometers. In addition tritiated hydrogen and hydrocarbons will be detected with flow proportional counter detectors and ionisation chambers down to the low ppm range. Inactive commissioning results will be presented.
