A solution of 50 mL contains compound A with unknown concentration. The peak area from GC-MS 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 (A1-A2)/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
