| The Amino Acid Geochronology
Laboratory at the Institute of Arctic and Alpine Research (INSTAAR)
was developed to address the timing of Quaternary events using
a relative dating technique that has a temporal range greater
than that of several common absolute dating techniques. Originally,
many of the sample types analyzed in the lab were Canadian Arctic
mollusks, but sample types have branched out over the years
to include bird eggshells, algal remains, synthetic amino acids,
and more. Our instrument capabilities have increased over the
years as well. Beyond the traditional ion-exchange liquid chromatograph,
we also use a reverse-phase liquid chromatograph that has up
to 100 times greater sensitivity. With these tools we are able
to handle a broad assortment of sample types and sample sizes.
This enables us to address a wider range of questions in Quaternary
geology. |
