Current methods use different
achiral stationary phases for diastereomer separation, while chiral columns are used for enantiomer separation [14, 15, 18].
The method validation was performed on spiked biological samples and found to produce complete separation of the synthetic cathinone enantiomers on
achiral capillary GC column in addition to sensitive detection of low concentrations in the [micro]g/L range better than the previous reported methods that use EI and positive CI ionization mass spectrometry.
In most cases differences in activity in either qualitative or quantitative terms are observed between enantiomers.") Enantiomers would only have the same effect if the target binding site were
achiral, and pretty much every molecule in your body of reasonable size is chiral.
not resolved by the
achiral column, only two peaks are observed.
Since the helical shape itself is chiral, if we can synthesize a polymer with a stable one-handed helical structure from an optically inactive
achiral monomer, the polymer must be optically active.
The others are
achiral polarization settings that are sensitive to different vibrational modes.

achiral and chiral pharmacokinetic behavior of intravenous oxfendazole coadministered with piperonyl butoxide in sheep.
In this unique class of optical materials formed by mixing chiral and
achiral nematics (with or without polymer stabilization), the molecules self-assemble into tightly wound defect-spirals that form 3-D cubic or BCC lattices with sub- wavelength lattice constants.
This relationship not only enables us to investigate the relationship among the regions and crossings of a reduced alternating
achiral knot but also their relationship to the vertices, edges and faces of the corresponding planar graphs..
