“…The works included in this table are those in which the lowest LODs were obtained. MS detection has been employed in other works on chiral analysis by CE but LODs close to or above 10 25 M were generally obtained [125][126][127][128][129][130][131][132][133]. The basic instrumentation in CE-MS [134] allows, once the electrophoretic separation is performed, the introduction of the analytes in the mass spectrometer using an interface, usually a sheath liquid interface, which enables the establishment of the electrical contact and the nebulization of the solution.…”

“…[31][32][33][34] Nestes casos, para evitar a contaminação do detector pelos componentes não voláteis do eletrólito (tensoativos, ciclodextrinas, etc), uma alternativa de acoplamento denominada preenchimento parcial (PF -partial filling) foi proposta. 35 Em PF-MEKC, por exemplo, o capilar é primeiramente preenchido com o eletrólito apropriado para o acoplamento com MS (volátil), seguido pela introdução do eletrólito micelar e, finalmente, pela injeção da amostra. Os analitos se separam no eletrólito micelar de acordo com suas hidrofobicidades e, então, migram para o eletrólito volátil, livre de tensoativo, seguindo em velocidade constante até o detector.…”

“…Moreover the identical masses of analytes that are just resolved in a chiral separation system are a very reliable indication of the presence of two enantiomeric compounds. However, to avoid ion-source contamination, chiral selectors such as cyclodextrins must be prevented from entering the detector, eg by the use of a partial filling technique (Tanaka et al, 1998;Muijselaar et al, 1998).…”
