Miniaturisation of sample systems constitutes one of the most promising techniques to improve both efficiency and analysis time of onsite sampling. Yet the modification of current systems to suit a portable and miniaturised format has proven very difficult. One of the key aspects for such compact sample analysis is the development of new chromatographic supports. Capillary and chip formats have taken a more defined role in developing miniaturised and portable systems, increasing the pressure on the development of novel chromatographic materials.
