The main scientific goal within the project -Two-dimensional high performance liquid chromatography in microfluidic chip devices- is the development of a miniaturized analysis system for fast analytical characterization of complex sample mixtures by multidimensional chip-based chromatography. Central aspect of the research work is the dead volume-free coupling of two pressure-driven chromatography units with particulate stationary phase by applying lab-on-a-chip technology. With this approach based on highly efficient coupling of chromatographic columns the great potential of multidimensional HPLC in microfluidic chips will be systematically investigated. Thereby, it should be possible to exploit the benefits of multidimensional nano-HPLC and to smartly bypass the technical hurdles of this technology, which are well documented in literature. Within the project microfluidic systems for two-dimensional chip chromatography are developed and the possibilities and limitations of this promising technology will be evaluated in detail.

该项目的主要科学目标-微流控芯片设备中的二维高效液相色谱-是开发一种小型化分析系统，用于通过多维芯片色谱法快速分析复杂样品混合物。研究工作的中心方面是通过应用芯片实验室技术将两个压力驱动色谱单元与颗粒固定相无死体积耦合。该方法基于高效耦合色谱柱，将系统地研究多维高效液相色谱在微流控芯片中的巨大潜力。因此，应该有可能利用多维纳米HPLC的好处，并巧妙地绕过该技术的技术障碍，这在文献中有很好的记载。在该项目中，开发了用于二维芯片色谱的微流体系统，并详细评估了这种有前途的技术的可能性和局限性。
