High-performance liquid chromatography (HPLC) is pivotal to
the purification of high-value compounds, from small molecules up
to biomacromolecules. Most commonly employed chromatographic
modes are reversed phase (RPC), hydrophobic interaction
(HIC) and ion-exchange chromatography (IEC), as well as their
combinations, which all typically operate under an organic solvent
or salt gradient . Apart from environmental stress, thispractice is associated with reduced product bioactivity and
increased costs particularly in the pharmaceutical and
biotechnological sector, where target-components are sensitive
and purification costs represent a major part of the overall production
costs Temperature-responsive chromatography has been
proposed as an alternative method to overcome above mentioned
limitations
