The Amino Acid Geochronology Laboratory 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.
