Week 2 - Day 3

Today the veteran put the foreign powers to the test by pulling out an old batch of DNA and left us alone to test the ions present in the solution. The foregin fact passed fairly sucessfully with most of the data corresponding to Johns previous tests. One of the calibrating solutions (80ppb) had a out lying concentration of Cobalt, which threw the calibration and results off a little. But all and all a good day, and feeling more comfortable using the equipment.
