Precision And Accuracy

Abstract Second derivative ultraviolet (UV) spectroscopy is used for the identification and quantitation of nitrates in water, with satisfactory precision and accuracy. Nitrite interference is eliminated with sulfamic acid; interference from organic matter can be cancelled with the use of second derivative UV spectroscopy. The nitrites can be calculated indirectly.

Abstract A method for the quali-quantltatlve evaluation of pentachlorophenol (PCP) in solid matrixes has been developed. The procedure Is based on solid-liquid extraction of solid samples (leather or wood), followed by purification on a cyanopropyl column and determination of the preservative by second derivative UV spectroscopy considering the PCP A peakthrough value (304-297 nm). The method allows rapid PCP determination In the concentration range 1-40 μg/mL; any matrix interference is avoided by the purification step and recoveries of the preservative were 99.12% (RSD% 0.13) for the leather matrix and 98.03 (RSD% 0.17) for the wood matrix.
