  • What is the best way to do trace metal sampling?

    All samplers contaminate or distort in some way. • Plastics may leach metals from ultraviolet inhibitors, metal-organic plasticizers, (rarely) metal catalysts. • Teflon has a rough porous surface into which ions, fine charged particles, and very fine particles may become attached. Errors may occur in your first sample due to these trapped trace elements. • ...

  • What are Kemmerer bottles?

    Based on a 1927 design by Dr. George Kemmerer, University of Wisconsin, the Kemmerer bottle has long been favored by limnologists and fishery biologists. With few moving parts and a foolproof trip, it offers a trouble-free life. Clear acrylic cylinders have the advantage of being transparent: you can see the sample before removal. You can also install thermometers inside acrylic samplers. ...

  • Buying time in suspended animation - Case Study

    Imagine being suspended in time—having your metabolism slow, heart rate decrease, and temperature drop. For Dr. David Kraus, Sulfide Biologist at the University of Alabama, linearity and precision matters. Dr. Kraus and other scientists are discovering that by administering small amounts of H2S, they can buy time in suspended animation. In 2005, Dr. Kraus decided to take his experiments ...
