a

Excitation (λex) and emission (λem) wavelengths.

b

LDR = linear dynamic range in ng mL−1 extending from the limit of quantification (LOQ) to an arbitrarily chosen upper linear concentration.

c

LOQs were calculated using LOQ = 10SB/m.

d

LODs were calculated using LOD = 3SB/m, where SB is the standard deviation of 16 blank measurements and m is the slope of the calibration curve.

e

Relative standard deviation (RSD) = SF/IF x 100, where SF is the standard deviation of the average calculated from three emission measurements at medium linear PASH concentrations within same day.
