Restek is bringing the speed and reliability of Raptor LC columns into the HILIC realm with the addition of the Raptor HILIC-Si column. The Raptor HILIC-Si column simplifies the switch to HILIC because it delivers rugged Raptor performance, provides SPP column speed for faster analyses than traditional FPP silica columns, retains polar compounds without ion-pairing reagents, and is fully reliable, efficient, and selective with LC-MS compatible mobile phases.

Simultaneous, enantiomer-specific identification of chiral molecules in multicomponent mixtures is extremely challenging. With mass-selected photoelectron circular dichroism (MS-PECD) using an electron–ion coincidence imaging spectrometer, a compound can be identified as chiral without the need for any prior enantiomeric separation or enantiomer-selective complexation.
