摘要：

The possibilities for multicapillary tubes with channels 3-10 mu m in diameter and a total number of channels of about 2 x 10(5)-10(6) to be used as chromatographic columns are studied. It is shown that substances with a sufficiently high boiling point can be separated at temperatures of 20-30 degrees C in 2-3 min with an efficiency of about 1500 theoretical plates per meter (300 theoretical plates for a 20-cm column).
