Well NIOSH, EPA and NASA was developing miniature technology in the 1970's! See report at the link below. http://nepis.epa.gov/Exe/ZyNET.exe/20006W7O.TXT?ZyActionD=ZyDocument&Client EPA&Index=1976+Thru+1980&Docs=&Query=700780184+miniature+gas+chromatograph&T ime=&EndTime=&SearchMethod=3&TocRestrict=n&Toc=&TocEntry=&QField=pubnumber^% 22700780184%22&QFieldYear=&QFieldMonth=&QFieldDay=&UseQField=pubnumber&IntQF ieldOp=1&ExtQFieldOp=1&XmlQuery=&File=D%3A\zyfiles\Index%20Data\76thru80\Txt \00000002\20006W7O.txt&User=ANONYMOUS&Password=anonymous&SortMethod=h|-&Maxi mumDocuments=10&FuzzyDegree=0&ImageQuality=r75g8/r75g8/x150y150g16/i425&Disp lay=p|f&DefSeekPage=x&SearchBack=ZyActionL&Back=ZyActionS&BackDesc=Results%2 0page&MaximumPages=1&ZyEntry=1&SeekPage=x The instrument was profiled in Scientific American during this period. Developing miniature intelligent detectors has been a decades old goal. -----Original Message----- From: DCHAS-L Discussion List [mailto:DCHAS-L**At_Symbol_Here**list.uvm.edu] On Behalf Of Kristi Ohr Sent: April 22, 2010 7:13 AM To: DCHAS-L**At_Symbol_Here**LIST.UVM.EDU Subject: Re: [DCHAS-L] Interesting Article For Contaminant Detection If you're interested in this sort of thing, check out Nate Lewis at Caltech. He makes electronic noses (and I believe he actually was the first to do so). He showed a video at a talk one time that showed robots with these noses that were able to respond to "smells". ________________________________ From: DCHAS-L Discussion List on behalf of Andrew Gross Sent: Wed 4/21/2010 9:51 PM To: DCHAS-L**At_Symbol_Here**LIST.UVM.EDU Subject: Re: [DCHAS-L] Interesting Article For Contaminant Detection Hi Everyone! Sensors and biosensors have been a personal interest of mine for a long time. Their application to defense is obvious, however it is not hard to see the expanded roles they will play in EHS. That being said, I found this article on CNN, it doesn't say much as far as scientific knowledge (almost laughable actually) but I thought that many of you would take interest in this type of research considering how it can be applied. I don't know much about this specific sensor, but if anyone is interested in opening a discussion, you can consider me an informed enthusiast willing to share what I know. http://news.blogs.cnn.com/2010/04/21/security-brief-cellphones-to-smell-bioc hem-attack/?hpt=C2 -Andrew On Wed, Apr 21, 2010 at 2:39 PM, Ralph Stuartwrote: > Pathology tables for Trimethylolpropane triacrylate (rats) (TR-576) have > been updated and are available on the NTP website at URL: > http://ntp.niehs.nih.gov/go/35528 > A complete set of data tables (body weight, clinical observations, survival, > and pathology) for studies planned for peer review are available on the NTP > website at URL: > http://ntp.niehs.nih.gov/go/peerreview > >
