Example text
ACS Symposium Series; American Chemical Society: Washington, DC, 2015. ch002 For example, during the irst EPA certiication for the Water Lab in 1974, the lab failed to accurately determine the sulfate ion concentration in the unknown sample provided. The analyst was concerned because he was conident that he had performed the analysis to the best of his ability. The oficial who had supplied the sample from the EPA explained that he had diluted the 10 mL sample with Ozarka brand water purchased from a Safeway.
Peer mentorship also allows analysts to learn important techniques within the lab. This was recently highlighted in the turnover of our ICP analyst. Our ICP-MS is an expensive instrument to operate due to the cost of parts and argon used to operate the instrument. Warm up of the instrument takes almost an hour and typical analysis takes several hours. Procedures must be followed exactly or the results are excessively costly. For the last two years, we had a dedicated student analyst running the ICP for both the lab and departmental student research projects.
Analytical techniques are also applied during the instrumental section of the class. The irst several experiments enforce the concepts of UV-Vis spectroscopy, then in the next experiment, iron is determined by colorimetry in method SM 3500-Fe D (4). In this technique, HACH Ferrover® packets are added to a water sample and an orange-red color results if dissolved iron is present. The students irst determine the wavelength of maximum absorbance and plot absorbance at this wavelength versus concentration.
