Question

Hello, I'm looking to verify I'm doing these correctly. Please show all steps, so I can figure out where I'm going right/wrong. I will hit like if comes back correct. Thank you! Have a good evening!

2. internal standard method A forensics lab performs trace analysis for residues of the explosive triacetonetriperoxide (TATP), using an HPLC separation method combined with mass spec detection. conc, ng/ul Current for Current for 1.854 4.385 Sample TATP, UA DADP.

Plot the TATP data twice, with internal standard correction (form the ratio). Attach your data plots showing equation of line and R2 values. fuse all good graphing conventions once without internal standard correction, and once
