NMR and IR spectroscopy are comparable to MS in identification potential if there are a relatively large amount of analytes and a simple composition of a sample under analysis. In NMR, algorit

In non-target/unknown analysis, approaches to identification should be validated, which include evaluation of pertinent databases, spectral libraries, predictor programs, identification/classification algorithms, and so on. Interlaboratory studies provide assessment of laboratory

General principles for identification through the use of chemical tests and instrumental measurements are formulated. Qualitative analytical procedures and approaches to implement them are classified. Component

False results are demonstrated to be attributes of determination of low analyte amounts by screening methods. Formulas for calculating rates of true and false, positive and negative results are given. The rates are derived bo

An example is the presence of a particular mass chromatographic peak in a rather wide range of the retention parameter. Most chromatographic

Andrea Maurer,Marina Müller,Gabriele Siegert divided into meaning and statistical data. Knowledge with regard to the origin, properties, and use of chemical compounds is very essential in order to be able to propose and reject candidate compounds for identification. Prior information about samples analyzed is important in order to gather full
