Interplay: Science - Society Now you need to consider The areas in Hot Pink Fitch, Alanah, Yunlong Wang, Sean Mellican, and Susan Macha: Lead Lab Teaching Instrumentation with One Analyte. Analytical Chemistry, 1996, Dec. 1, 727 A.

Designing a Standard Operating Procedure 1. You know how to select an instrumental method 2. You know how to create a calibration curve 3. You know how to assess the “precision” of the calibration curve 4. How are you going to assess the accuracy of your 1. Sampling 2. Digestion 5. How are you going to confirm the stability of the instrument?

Dates and responsible parties Laboratory certification

Validated method Document chain of custody Instrument drift is monitered Not the same as calibrated – for example checking gas flows, magnet capacity, intensity of the voltage for a source lamp, etc

Controls to document Worker/instrument/method capacity

Validated method

Internal standards

Based on your previous work 1. How many separate digestions will you need to do on your sample to assess the precision of digestion? 2. How will you confirm that the digestion procedure does not add lead to the final answer? 3. How will you confirm if your individual ability to perform the digestion is compromised? The answer to these questions results in a standard Operating procedure. Today: cosmetologists consult the literature search lists I have posted to determine which articles you need to retrieve from off campus. This needs to be done today in order to have the information back by the weekend For Friday: “loyola is killing us group” – consult the labs on the web page to find the standard operating procedure for dust wipe sampling and digestion
