Regression equation, the limit of detection (LOD), the limit of quantification (LOQ), and relative standard deviation (RSD) for MIT, CIT, OIT, and triclosan.

Target	Regression equation	Correlation coefficient	LOD (mg L^−1)	LOQ (mg L^−1)	RSD in the same day^a %	RSD in 6 days^a %
MIT	Y = 0.8360X − 0.0598	0.9999	0.11	0.36	1.8	2.4
CIT	Y = 0.6460X − 0.0308	0.9998	0.08	0.28	2.5	3.8
OIT	Y = 0.4180X − 0.0309	0.9997	0.12	0.38	2.8	3.9
Triclosan	Y = 0.3601X − 0.0245	0.9995	0.06	0.21	1.9	2.9

Y = peak area, X = mean concentration (mg L⁻¹), linear range = 1.0–5.0 mg L⁻¹, and ^an = 10.
