Hi
A solution of 50 mL contains compound A with unknown concentration. The peak area from GCMS for this compound is A1.
The same solution is treated to remove compound A. After treatment the solution volume is reduced to 30 mL and compound A also reduced to some extenet. The peak area from this sample is A2.
In this case how to calculate the removal % of compound A using peak area information?
Generally, we can calculate the removal % from peak area using the formula (A1A2)/A1 *100.
How do we calculate the removal percentage when volume is changing? Do we need to consider the change in volume when the removal % is calculated from peak area?
Thanks
