Abstract:Despite of exhaustive literature information, analysts are still fronting serious problems in estimating the uncertainty of measurement (UOM), mainly because of the intrinsic difficulties in choosing an appropriate approach and/or of an inadequate background in statistics and metrology fundamentals. Sometimes, additional problems, at present under debate, make their efforts even more stressful. In this paper, attention is mainly paid to intra-laboratory estimation of UOM, the most frequent situation. After a s… Show more
“…The energy separation of the major excursions in the first derivative of the carbon KLL spectrum varies with the chemical state [13]. It was suggested that the value of this separation in a certain energy range also increases the certainty that the carbon is present as contamination.…”

“…For example, alkaline treatment of 5-methylamino-4-nitroisoxazole 218 leads to oxime 219 along with methylamine [309]. The process proceeds with initial nucleophilic attack at the 5-position of the isoxazole ring.…”
