Separation Science Applied to Analyses on Biological Samplescific examples to illustrate various aspects. Despite notable advances in the separation technology that must precede the application of a specific measurement procedure and I or detection device, many problems and difficulties remain. The difficulties are compounded by the development of instrument

Sample Handling in Forensic Toxicologysamples received for this purpose vary in quantity, variety and quality. The quantity and variety depend on the pathologist; the quality depends on the condition of the deceased and, to a lesser extent, on the pathologist. The task of the toxicologist can be assisted by good medical and circumstanti

Isotope-Labelled Materials as Internal Standardsquicker and easier than alternative methods and sometimes is the only solution to the problem. Chromatographic separation followed by mass spectrographs (MS) detection of test and isotopic labelled materials is generally considered to be the definitive analytical technique but is not without its dif

Approaches for Determining Ethylenediamine and its Metabolites: Use of [14C]- and [D4]-Ethylenediami, resins and dyestuffs, is present in cutting oils and wetting agents, and is used in pharmaceutical formulation. Our interest in ethylenediamine stems from its presence in the widely used bronchodilator drug, aminophylline, which consists of theophylline and ethylenediamine in a molar ratio of 2:1.

Selective Sample Preparation Techniques for Trace Analysisistorically [cf. R.P. Maickel, #A-1 -..], solvent extraction has been the principal technique used for sample preparation; now solid-phase materials such as bonded silicas and small-particle resins are becoming accepted as convenient and efficient extraction sorbents. Two types of these solid-phase

Optimization Strategies for Chromatographic Analysis of Multi-Component Mixturestion conditions have been chosen, e.g. type and mode of use of chromatographic column and mode of detection, a number of continuously tunable variables can be used to optimize the overall analytical procedure. Necessarily a criterion has to be defined that permits an objective judgement of the resul

Chemically Bonded Stationary Phases in (HP)TLCLC on chemically bonded phases occupies a rather modest position. This is in marked contrast with the situation in HPLC where much work is done with chemically bonded phases, especially C-18 and C-8 modified silicas. Still, in recent years the widespread use of these apolar stationary phases in what
