Table A2.

Determination of the Limit of Detection (LoD) and Limit of Quantification (LoQ) values for all hydrogel-based ethanol sensors in Section 3.4.

Sensor	sL [mV]	b [mV/vol%]	LoD [vol%]	LoQ [vol%]
Sensor #9	1.46	2.28	2.11	3.78
Sensor #10	0.16	1.72	0.31	0.55
Sensor #11	0.13	2.60	0.17	0.31
Sensor #12	0.17	3.13	0.18	0.32
Sensor #13	0.04	2.61	0.06	0.10
Sensor #14	0.53	2.66	0.65	1.17

s_L: standard deviation of the sample without the analyte, b: slope of the calibration curve (sensitivity).
