Table 2 Mean recoveries (in percent), RSD (intra-day and inter-day, n = 6) for matrix-matched (C) and (G) at three levels of spiking (83, 166 and 333 mg kg-1) measured over 2 days. Limits of quantitation (LOQ, S/N = 10) for matrix matched (C) and (G) expressed as milligrams per liter and milligrams per kilogram
