General Description
TheSENSIT®InfraredEthaneDectector,referredtoas“IRED”,isdesignedtodetectthepresenceof
ethanegasinamethanegassample.TheIREDcandetect250partsperbillion(ppb)upto500ppm
ethane.TheIREDisusedtodetermineifmethanedetectedintherangeof50-2000ppmisofsimilar
make-uptothatofpipelinegas(whichcontainsethane)orisnaturallyoccurringmethanefromother
sourcessuchasorganicdecay.TheIREDisnotdesignedforhighconcentrationsordeterminingactual
ethanecontentfromwithinapipeline.
TheIREDsensesgasusingInfrared(IR)AbsorptionSpectroscopyincombinationwithanelectronic
narrowband-passlter.Thistechnologyutilizesaninfraredlightsourcewithanoutputthatischanged
when certain gases absorb the light output.  The lter only allows specic light wavelengths to be
monitoredandmeasured.TheconcentrationofgasisproportionaltotheamountofspecicIRlight
absorbedandisdisplayedinPPBorPPM.
TheIREDhasalargedisplay indicatingbothsustainedandpeakreading concentrationsandother
instrumentfunctions.Aninternalpumpprovidesrapidsamplingintothedetectionchamber.Bluetooth
data transmission provides communication of real time and stored data. Optional GPS with Data
Loggingallowforfurtherrecordingoftime,dateandlocationdata.

Ethane (C2H6) to Methane (CH4) Ratio
WiththeuseofaSensitIREDandPMDyoucanaccuratelyandefcientlydeterminethepercentage
ofethaneinamethanesamplebetween50-2400ppm.Therearetwomethodstoachievethedesired
resultswhichareoutlinedbelow.Thepicturebelowdepictsthetelescopicprobe(barholeprobemay
alsobeused)attachedtotheinletoftheIRED(withpumpon)andthePMD(withpumpoff)inlet
attachedtotheexhaustoftheIRED.Thisallowsbothdevicestoosimultaneouslyanalyzethesame
sample.

Method 1 - Procedure for IRED/PMD Paired Sample Analysis to
Simultaneously Analyze the Same Sample
1. WiththeprobeofchoiceattachedtotheinletofthePMD(PumpOn),searchforanacceptable
stablesamplesizerangingfrom50-2400ppmCH4.
2. DisconnecttheprobetubingfromthePMD(leavetheprobeinplace).TurnthePMDpumpoffand
attachthepairinghosetotheIREDexhaustandthePMDinlet.
3. StartthezeroingprocessontheIRED.Uponthecompletionofthezeroprocess,theIREDwill
beepanda120secondscountdowntimerwillbedisplayed.
4. Attachtheprobeofchoicethatisstillinplacefromstep2totheinletoftheIREDandpressthe
“B”buttontostartthetest.Thetestwilllast40seconds.
5. Duringthetest,monitorthePMDmethanereadings.Notethepeakmethanereadingduringthe
40secondtest.Thiswillberequiredtoestablisharatio.
6. Attheendofthetest,theIREDwilldisplay“RESULT”andbeep.Thepeakethanereadingwillbe
displayed.
7. Basedonthepeakmethaneandethanereadings,referencethemethane/ethaneratiochart
providedinthissection.
8. Repeatsteps1through7toperformanotheranalysis.
Method 2 - Procedure IRED/PMD Independent Sample Analysis
1. WiththeprobeofchoiceattachedtotheinletofthePMD,searchforanacceptablestablesample
sizerangingfrom50-2400ppmCH4.
2. StartthezeroingprocessontheIRED.Uponthecompletionofthezeroprocess,theIREDwill
