a plus1 story
“Sincenowalmost 15years , theLaboratoire Interuniversitairedes
SystèmesAtmosphériques (LISA) of theUniversityof ParisXII has
beendevelopingGC subsystems foron-board spaceprobeGCMS
experimentsdedicated to the insitu analysisof extraterrestrial
environments.Mostof thecapillarycolumnsused in these subsystems
wereand still areprovidedby theRestekcompany.
Onecapillarycolumn,MXT®-17011,wasaboard theHuygensprobeof
theCassini-Huygensmissionwhichexplored successfully in2005 the
atmosphereofTitan, the largestmoonof Saturn. Four columns,
MXT®-1, 20, 1701andMXT ®-UPLOT2, are“en route”towards thecometChuryumov-Gerasimenko in the
frameof theESARosettamission launched in2004 toarriveby2014. Theywill beused for the first time
insitu analysisof acometarynucleus. And finally, so far, 4other PLOT (MXT ® U) andWCOT3,4 (MXT®-1, 20
andCLP) columnshavebeen selectedandarecurrentlybeingbuilt in theGCof theSampleAnalysisat
Mars (SAM) Pyr/GCMS instrument, partof thepayloadof theNASAMSL2009Marsexploratorymission.
Iwould like tomention that all thecolumns selected for spacemissionareSilcosteel® treatedmetal
capillarycolumnsand theyhaveall been submitted successfully to spacequalification tests suchas
vibration, radiationand thermal cycles5,whichdemonstrated their robustness for spaceapplication.
Since thebeginning, theRestekcompanyhasbeenmore thanamanufacturerprovidingLISAwith
columns. Indeed, ithasbeen stronglycollaboratingandhelpingLISA todevelopcustom-madecolumns
able tomeet the requirementsof suchanunusual scientificgoal for chromatographiccolumns. That is
whyLISA isverygrateful toRestek forbeing this ideal partnerwithout thehelpofwhich the studyand
developmentof chromatographiccolumns for spaceusecouldnothavebeenpossible.”

*For simulated distillation.
Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengthsmay have a slightly reduced
maximum temperature.
MXT®-1Columns (Siltek® treatedstainlesssteel)
(nonpolar phase; Crossbond®100%dimethyl polysiloxane)
• General purpose columns for solvent impurities, PCB congeners (e.g.Aroclor
mixes), simulateddistillation, drugs of abuse, gases, natural gas odorants, sulfur
compounds, essential oils, hydrocarbons, semivolatiles, pesticides, andoxygenates.
• Temperature range: -60 °C to430 °C.
• Equivalent toUSPG1,G2,G38phases.
MXT®-1 columns exhibit long lifetime and very low bleed at high operating tempera-
tures. A proprietary synthesis process eliminates residual catalysts that could cause
degradation and increase bleed.
