and Measuring Concentrations ·
Tasks for
Today o
Organize
information from chromatograms retention times peak areas
o
Use Excel
to make a standard curve for your group’s anion
peak area is proportional
to anion concentration use data from entire class (15+ points!) find equation of the best fit line to use in
spreadsheet calculations o
Identify
anions in each drinking water use retention times
known from anion standards o
Find
concentration of each anion in each drinking water convert peak areas
into concentration via spreadsheet
calculations use best fit lines
from standard curves Week 2 Report o
Data section due today at end of lab o Email Excel workbook to yourself before
leaving today. o
Work independently
on report calculations/questions o
