(ă-kī'răl),
Not chiral; denoting an absence of chirality.

achiral

pertaining to the absence of chirality in a compound, as in stereochemical isomers.

achiral

adjective Referring to a molecule or material which is superimposable on its mirror image—i.e., does not display “handedness”

Built on the company's UrtraPerforrnance LC (UPLC) technology, the sys tem offers up to 10x shorter run times, reduces solvent usage by as much as 95% and cuts the cost of analyses by as much as 99%, while giving laboratories a greener alternative to normal phase chromatography for chiral and achiral separations.
System offers greener separations option
Hence, a chiral medium gives more freedom to adjust (decrease or increase) the reflection and transmission, because it can be controlled by variation of three parameters ([epsilon], [mu] and k) instead of two parameters ([epsilon] and [mu]) as in the case of achiral medium [2-4].
