NANO-MICRO-SPECTRO – Lake Superior State University student Julia Peterson gets to know the chemistry lab's latest analytical acquisition, a BioSpec-nano Micro-volume UV-Vis Spectrophotometer. The instrument analyzes samples by measuring how they pass or absorb light from a precisely calibrated Xenon flash lamp. Sample sizes can be incredibly tiny - down to 1 microliter or 0.00020288411948900794 of a teaspoon. The instrument will bolster student and faculty research in biochemistry, forensic chemistry, and environmental science. LSSU's Environmental Analysis Lab will also use it, along with quantitative DNA methods (q-PCR), to measure fecal contamination at regional beaches and waterways. Run a Web search on "LSSU physical science" and "LSSU environmental lab" to read more about these programs and services offered through Lake State. Peterson is a junior pre-professional biochemistry major from Brighton, Mich. (LSSU/John Shibley)
