Hello Good People!

Well, this is an odd question, but...

Many years ago, I saw an article in Scientific American about
someone, somewhere who was going to etch a gas chromatograph
device into silicon, I guess for miniaturization purposes.  Does a modern
day, contemporary, device such as this exist??

I dropped Sci. American about the time they had a cover story emblazoned
with the notion that protons 'might' appear/create themselves,
'spontaneously'
in 'space', even I knew this was wrong.

Well, colledge physics was confusing and I never did pick up this magazine
again to see if this little machine had been created.  So,if you know of
such
a thing, please let me know where I might find something like this, I want
to
hook it up to a pic to sort of make an analysis machine,


--thanks
