Week 1 Day 2

This morning we continued to read articles and catch up on latest research in the field.  Then in the afternoon we started making calibration samples.  I am making 10 samples, each 10 mL.  They each have 1 ppm of Co, 0-5 ppm of Mg and Na, and 0-1 ppm of P.  The rest of the sample is water.  I started out with the water.  Came out fine on the percent errors.  However I had to redo three of the samples next, when I added the Co.  Third, I added the Na.  Some of the percent errors were a little high, but not high enough to redo the samples.  Today I will finish adding the Mg and P.
