Tab. I.
Analytical data of the acrylamide standard solution analysed by HPLC-UV: linear regression equation (peak area/conc.) and correlation coefficient (R2) calculated in the linearity range 0.05-2 μg/g at wavelengths 210 and 200.5 nm; limit of detection (LOD, s/n = 3/1) expressed as μg/kg; limit of quantification (LOQ, s/n = 7/1) expressed as μg/kg; intra-day RSD and inter-day RSD (n = 3).
| Linear regression equation | R2 | LOD (μg/kg) | LOQ (μg/kg) | Intra -day a RSD | Inter-day b RSD | Wavelength |
