| 摘要 |
<p>The invention concerns a non-thermosensitive liquid medium for analysing, purifying or separating species in a channel and comprising at least a polymer consisting of several polymeric segments. The invention is characterised in that said polymer is of the irregular block-copolymer or irregular comb-like polymer type and has on the average at least three junction points between polymeric segments of different chemical or topological nature. The invention also concerns methods for analysing, purifying or separating species using a non-thermosenstive separation medium.</p> |
