Abstract:
... A new carbazole-based spherical microporous polymer (Car-BDA-POP) was fabricated by employing 4,4′-biphenyldicarboxaldehyde (BDA) and carbazole as monomers via a one-step and non-metal catalyst synthetic approach. It was then explored as an adsorbent for solid-phase extraction (SPE) of some chlorophenols (CPs). Under the optimized extraction conditions, the established Car-BDA-POP-based SPE couple ...

Abstract:
... Parahydrogen hyperpolarization has been shown to enhance NMR sensitivity in urine analysis by several orders of magnitude if urine samples are prepared by solid phase extraction (SPE). We present a different approach, developed for minimal sample alteration before analysis. Removing SPE from the workflow allows to retain a wider range of metabolites and paves the way towards more universal hyperpo ...
