Percent coefficient of variation

Compounds	Target Ion m/z	Qualifier Ion(s) m/z	t_R(min)	r²
1,4-dichlorobenzene (IS)	152	150, 115	8.89	N/A
Propoxur	110	152	17.49	0.987
Transfluthrin	163	91, 335	20.71	0.988
Bioallethrin	123	79, 136	22.53	0.994
Cyfluthrin	206	226	31.84	0.999
Cypermethrin	181	209	32.99	1.000

¹Percent coefficient of variation is calculated as the standard deviation/mean recovery x 100
