Tasklist for Friday, September 2, 2016
- Take one of the pipetters and test its accuracy and precision. Use a minimum of 10 trials.
- Measure the conductivity of tap water, DI water, HPLC water, and LCMS water
- Measure the water content of a sample of CaCl2
- Measure the fluorescence of pure water. Was it clean?
- Prepare several stock solutions
- 100 mL 200 ppm Malachite Green
- 100 mL 3 wt% bentonite
- 200 mL water + 40 g Na2SO4 + 4 mL H2SO4 (conc.)
- 250 mL 1.0 M HCl solution
- 250 mL 0.2 M sodium bicarbonate solution
- Prepare PVOH films
- 1 g PVOH + 0.5 mL 8% glutaraldehyde in 12 mL water
- 1 g PVOH + 0.1 g bentonite + 0.5 mL glutaraldehyde in 12 mL water
- 1 g PVOH + variable amount of a crosslinking agent (either equivalent moles of glyoxal or a different quantity of glutaraldehyde) w/o clay
- Read over the bead protocol here
- Prepare 50 mL of PVOH / bentonite / HCl
- write a procedure for producing beads using all your PVOH solution
