Iron Analysis

Thursday May 5th
More iron analysis today. We started by picking up our samples in AESB (ag engineering building). The muffler gets over 500 degrees celsius, so we had to let them cool for awhile before we could remove them. We transported them back to the lab (goodness it was hot outside!) and let them cool a but longer in the polar fridge (we went inside for while to cool down ourselves). Once the samples were cool enough to analyize we labelled our tubes and weighed out the ashes into each tube. We then mixed our reagents (chromogen and BHT solutions; highly acidic). We then diluted to our recommended amount and analyzied our samples in the spectrophotometer. It was actually pretty rewarding to do the same procedure from my first couple weeks at internship. This time it was with real samples, but I still feel more confident knowing I've come so far in my research skills.
