Provided is a frit having a body comprising a matrix material, and a plurality of microcapillaries formed within the matrix material, the microcapillaries substantially aligned with a longitudinal axis of the body. The frit may comprise a microstructured fibre, such as a photonic crystal fibre. The fit may be coupled to a fluidic conduit such as a chromatography column and/or a nanoelectrospray emitter. The frit may be used in applications such as solid phase extraction, electrospray ionization mass spectrometry, microreactor systems, and filtering particles in any fluid system where there is a need to retain particles.
