What Is Spectroscopy

Protea FTIR Vs. GC in Gas Analysis PDF
Protea AtmosFTIR

• A Replacement for many GC Apps

• a huge compedia o revolutionary Gas Analysis instruments

• analayis of up to 50 mixture components by HighRes IR simultaneously
   

• Anyhing which has a NON- symmetrical molecule
  eg but NOT H2, O2, N2, Ar,He, CCl4 (? perhaps)
  but also highly specific for toxics, NO2, NH3,

• some ~ 100ppB to low  % !

normally large spectra cell(Quartz)200cc
> very long path length ( via multi relection cells ) determines sensitivity > LODs
HIgh Flow rates >a few 100cc/min > 1 litre/min

Problems ( for us !)

High Tech , ultra-expensive, protected by “academics”
market dominate by business “gurus” protective > “attempts to corner the market”
perhaps stifled by patents ?

• NEEDS INNOVATION  and commercialising
  Maybe PROTEA Systems ? (watch this space ! )

• at least NO LN required ( ambient and MAX Temp ???)

• a design compromise,  resolution vs speed and need for a sample drier

• vs COST!  . . . and hopefully now within reason !

now MKS  ( > a “megopoly” > far too big for us  ?and  “ still a-bit-over-the-top ? “ )

• cell Temps ambient to 190degC(Viton seal?) > but with the beauty of GraphiteFerrules (?)
   ( maybe even higher ! . . . might they Be-a-Ware ! . . . ever !

• scans > 1/sec

• MKS 70cc Cell and inert ( DURSAN-coated
  > apparantly LN cooling require > a maor limitation for practical use and TOO New car emmission level technology ?
   

• but the High Res > does apparantly reduce interference from water & CO2
  5scans/sec but up to 10HZ
                                                                 > My guess > “megabucks” ?

In Australia don’t confuse with MKS(Foods) a “Take-a-Way”
 but also listed by John Morris > amongst “ many others” !

> the WORLD DOES Evolve < AND at the “speed of light” via “THE Internet”
> that’s if U can sort the Good from the “crap”
but MKS ??? anyone !

NDIR
Single Element Sensor
Multiple cell System NOW emerging as in-Series Sensor ”systems”

> & Affordable

generally large cells, path length for enhanced sensitivity

100ppM to100%v/v sensitivity

Manual Injection ( small sample 1-5cc)into a flowing purified gas stream
> @ reduced sensitivity - possibilities !
eg biochem APPS

:   fermentation cells ( CH4/CO2 Greenhouse R&D “ projects”,
:   CO2 sequestration

ASK ! re “unique” Analytical possibilities !

BUt we try NOT to speculate too much on projects viability
> often in the “lap of the gods” authentic scientists and not the folly of
“pseudo” scientists > the media and somewhat ignorant bureaucrats > politicians ? > “extremists”
 nor money grubbing opportunists !

• Chromalytic > intense interest !

• “Collaboration” seeked

• NOT for the” Faint-of-Heart” ( Guts !)

Our “general “policy” is to educate the Analyical Chemistry scientiic community to new technology\

Our more invovlement ? > as opportuniies continue open-up !
. . . belatedly perhaps ?

Let us be part of “YOUR” Learning curve we’ll leave it up to the
“bean counters” to exploit the situation the best they see fi

THE World “powers that be” have no regards for patents anyways >
 “extortion of small inventors” > business !

see also our “NEW” Technologies www.chromtech.net.au/newtechnologies.htm >intro
prime examples being
glass capillary columns technolgy commercialisation
“fast” GC
and our intense interest in TOF-MS ( and via some similar-mindeda collegues) at the ANZMSS )
‘thru  the ‘70s-80s >
HP CounterCurrentLC
& more recently new FTIR in particular as a potential replacement for GC

Personally I heve been intensely interested in ALT Nuclear Energy since the ‘70s
also at the risk of being also CANCELLED by the “(Australian) Establishment “mentality” !
