Lower limit of quantitation and limit of quantitation were determined based on signal to noise ratio.
* Limit of Quantitation - Six spiked sample solutions prepared where approximate signal to noise of compounds of interest is 10.
The performance characteristics that should be validated will vary depending on the purpose of the procedure and may include accuracy (precision and bias), limit of detection, limit of quantitation, linearity, working range, and selectivity.
Furthermore, limits of detection determined with the zero calibrator are generally far below the lowest concentration that can be reliably quantified in human serum [functional sensitivity (13,14) or limit of quantitation (LOQ) (15)].
Limit of quantitation (LOQ) measured as three times the LOD was 0.33 ng, 0.24 ng, 0.3 ng and 0.78 ng for GABA, Put, Cad and TY reading up to FID, respectively (Table 1).
The limit of detection and limit of quantitation for the method validation of H acid and Koch acid is derived from the residual standard deviation of a regression line based on detection limit co-efficient, and quantitation limit co-efficient 10.
The limit of detection (LOD) and limit of quantitation (LOQ) were the concentrations of a compound at which its signal-to-noise ratios were detected as 3: 1 and 10: 1, respectively.
It is typically not possible to determine the true upper limit of quantitation (ULOQ) and lower limit of quantitation (LLOQ), as QC material within a characterized range is not available (e.g.
Compared with participants in homes with levels below the limit of quantitation, those in households with quantified levels of S[O.sub.2], N[O.sub.2] and [H.sub.2]S were twice as likely to report doctor-diagnosed asthma; participants in homes with quantified levels of S[O.sub.2] were more likely to report wheezing symptoms.
