Test entry
- making solutions:
- remember solubility rules
- is solid hygroscopic ? NaOH solution better than solid.
- mass based best: volumes change with Temperature etc
- ppm = mg/kg for water density = 1
- use balance
- significant figures
- can use hydrate but need to use hydrate's molar mass
for ICP fill with LCMS water -- least amount of ions
use plastic flasks for small, accurate ionic concentrations
To Do
- Find a procedure template
- Find link to calculate mass for each reagent
- Find a glossary of techniques and equipment
- Add MSDS link
Today's Task List
- weighing boat weighs .54011 g
- added 1 g of PVOH
- boat with residues: .54242 g
- PVOH mass: 1.54011 - .54242 g
- added 500 microliters dialdehyde with 1000 microliter pipette
- transferred to Teflon dish
