Logbook of the GC/MS

Entry Name Date
The oil for the pump exchanged IG 09/02/2010
Exchanged 2 filaments and the temperature sensor on the source IG 20/11/09
Filament 1 broken. Simultaneously filament 2 gives error. After restarting the MS filament 2 works. Two new filaments are being ordered IG 06/10/09
In ISR, Device was connected to pipes full of water. Both GC and MS show huge amounts of water! Need to regenerate the columns (high T, detectors off) M.C. 10/6/09
Device moved to ISR by Ivan, tests of Stefano's gas with RPCs drawing high currents M.C. 9/6/09
GC/MS sent to SRA. Problem: double peaks in GC PPU column. SRA claims MSD Filaments are broken M.C. 15/04/09
Switch on GC/MS after repair. MS working fine M.C. 15/01/09
GC/MS back from SRA. Xmas shutdown... M.C. December 09
Area of MS signals varying significantly. SRA claims they need to repair the injection pump. Machine sent to SRA 1st week of November. M.C. October 09
The MS fillement exchanged I.G. 03/10/08
Power failure in build. 190. GS/MSD not switched off properly I.G. 27/8/08
Started firsts analysis with Filament 2 Ar@OV1@20min Files:ArgoninOV1flush I.G. 26/8/08
Changed 2 MSD filaments I.G. 22/8/08
