Astec chirobiotic tag guard column (ss)

Astec CHIROBIOTIC™ CSPs (chiral stationary phases) interact
with polar, ionizable and neutral analytes via multiple molecular
interactions. This versatility means that the same Astec
CHIROBIOTIC column can be successfully used in a variety of
mobile phases, a significant benefit over CSPs that operate only in
a single mode, normal or reversed-phase, for example, and must
be dedicated to those mobile phase systems. However, the most
interesting feature of Astec CHIROBIOTIC CSPs is the presence of
ionic interactions, which allows them to be used in polar ionic
and reversed-phase modes for sensitive LC-MS operation.
. The truly differentiating feature of Astec CHIROBIOTIC
CSPs is the presence of ionic interactions. These interactions are
unique to Astec CHIROBIOTIC CSPs and are responsible in large
part for their desirable retention characteristics toward polar and
ionizable analytes in aqueous and non-aqueous solvents.
