TRANSFER-FREE ELECTROPHONE REQUIREMENTS AND ELECTROPHONE REQUIREMENTS FOR THE PURPOSE OF THIS PROCEDURE

摘要

In a non-carrier electrophoresis process to separate a sample substance into its constituent parts, the sample is first subjected to coarse fractionation followed by a second-stage fine fractionation. In the first stage is conducted at high linear flow speed over a short migration distance. A smaller number of fractionating points is used in the first stage than in the second stage. The process stages may be conducted in parallel, in series, or in a combination of parallel and series. An independent claim is also included for an electrophoresis apparatus with a separation chamber, electrodes, sample and fraction sections. The separation chamber is sub-divided into smaller chambers with electrodes each serving two fraction chambers,.
