Weight of Standard = 5.0mg.
Purity of Standard = 99.2%
Diluted to 100mls for stock standard.
4mls of stock standard diluted to 100mls for working standard (this is the standard injected).
Weight of Sample = 2000mg.
Diluted to 50mls, then 5mls of this into 50mls for final sample solution (this is the sample injected).
Injection volume of standards/samples = 5 microlitres.
Formula in method for % (w/w)=
Weight Adjusted Sample/Weight Adjusted Bracketing Standard x (Purity/100).
Empower:
Average by (Amount or Concentration?)
