    • A method of fabricating a chromatographic column and columns produced by such a method are disclosed. The method includes: (a) obtaining a tube comprising two open ends and a lumen with a diameter of 75 microns or less extending between the two open ends; (b) depositing a liquid silicate composition into the tube lumen at a first open end of the tube; (c) forming a porous ceramic material from the composition in the tube lumen at a location near the first open end such that a space is formed between the ceramic material and the open end that is substantially free of the ceramic material; and (d) forming a tapered emitter having an orifice diameter of less than 3 microns at the first open end.
    • 公开了制造色谱柱的方法和通过这种方法生产的色谱柱。 该方法包括:(a)获得包括两个开口端和在两个开口端之间延伸的直径为75微米或更小的内腔的管; (b)在所述管的第一开口端将液体硅酸盐组合物沉积到所述管腔中; (c)在靠近第一开口端的位置处从管腔中的组合物形成多孔陶瓷材料,使得在陶瓷材料和基本上不含陶瓷材料的开口端之间形成空间; 和(d)在第一开口端形成孔径小于3微米的锥形发射器。
