Enantiomeric separations by capillary electrophoresis in pharmaceutical analysis
, 1999 The chiral capillary electrophoresis mechanism is studied by evaluating the enantiomeric separations of a series of local anaesthetic analogues, the sixteen different optical isomers of a tetrapeptide and a series of glycyl, alanyl and leucyl dipeptides.

Enantiomer separation using membrane systems [PDF]
, 2002 Many compounds applied in the agrochemical, food and pharmaceutical industry contain one or more chiral centers. The enantiomers of these compounds often have different effects on their targets.

Enantiomer fractions instead of enantiomer ratios
, 2000 The use of enantiomer ratios (ERs) to indicate the relative amounts of a pair of enantiomers in a sample has some disadvantages. Enantiomer fractions (EFs) are proposed as all alternative expression to eliminate the difficulties.

Monolithic enantiomer-selective stationary phases for capillary electrochromatography
, 2006 Monolithic materials have become a well-established format for stationary phases in the field of capillary electrochromatography. Four types of monoliths, namely particle-fixed, silica-based, polymer-based, and molecularly imprinted monoliths, have been ...

Enantiomer separation by ultrafiltration of enantioselective micelles in multistage systems [PDF]
, 2000 The Food and Bioprocess Engineering Group of Wageningen University, The Netherlands, is developing a new enantiomer separation system that is based on ultrafiltration (UF) of enantioselective micelles containing chiral selector molecules.

Enantiomer ratios, patterns and levels of toxaphene congeners in human milk from Germany.
, 2002 High resolution gas chromatography (HRGC) coupled to quadrupole negative ion chemical ionization (NICI) mass spectrometry (MS) was used to investigate congener patterns, levels and enantiomer distribution of selected toxaphene congeners (#26, #41, #44 ...
