Future trends in technical careers. Isotope ratios via Cavity Ring-down Spectroscopy
Filed under: Position Searching, Technicians, Observ. Trends
Posted by: site admin @ 7:33 am

History has seen the invention of techniques be
the forerunner of major breakthroughs– mass
spectroscopy, hplc, nmr and many others.

Last February, I attended a lecture featuring
Dick Zare describing Cavity Ring-down
spectroscopy
that he and his colleagues have
developed.  It can be used to measure C, H,
O, N isotope ratios.  Applications for this method
include:


  - water sources in mixed streams
  - geographical origin of plant species
  - early detection of ulcers
  - geochemistry of coal and petroleum reserves
during exploration
  - understanding the sources and sinks of
“greenhouse gases”  2
