^aPrecision values are percent relative standard deviation. The limit of detection (LOD) and limit of quantitation (LOQ) are reported in micromolar (bold, top values) and μg/L (bottom values). The linearity and limit values are the means of the three different batches (n = 3) and include standard deviation (±value).
