    • The invention provides improved methods and apparatus for fluid chromatography, and is particularly appropriate to high-pressure liquid chromatography carried out using eluent flow rates less than 1 μl/minute, for example on nanoflow columns. In both single- and multi-dimensional chromatography systems, especially those comprising trapping media to facilitate injection of relatively large volumes of sample on to nanoflow columns, the on-line addition of a diluting solvent enables stronger eluents and sample solvents to be employed without causing premature release of analytes from the trapping media or the degradation of the second dimension chromatographic separation. The invention may be advantageously used for two-dimension reverse phase/reverse phase separations, especially for the separation of complex mixtures of peptides.
    • 本发明提供用于流体色谱法的改进的方法和装置,并且特别适用于使用小于1mul /分钟的洗脱液流速进行的高压液相色谱法,例如在纳流方柱上。 在单维和多维色谱系统中,特别是包含捕集介质以促进将相对较大体积的样品注入纳流柱上的系统,在线添加稀释溶剂使得能够使用更强的洗脱液和样品溶剂而不引起 从捕集介质过早释放分析物或第二维色谱分离的降解。 本发明可有利地用于二维反相/反相分离,特别是用于分离肽的复杂混合物。

    • An apparatus for conveying fluid comprising a first tube and a second tube. The first tube has a first end and a second end, an inner wall and an outer wall. The inner wall defines a passage for fluid and an outer wall has at least one first receiving section for receiving an inner wail from the second tube. The second tube has a first end and a second end, an inner wall and an outer wall. The inner wall defines a chamber for receiving the first tube and has at least one second receiving section for receiving the outer wall of the first tube wherein at least one of the first tube and the second tube are drawn down such that the first receiving section and the second receiving section of the first tube and the second tube are in close proximity to each other and sealed.
