Abstract: PURPOSE: To obtain a filler for a high speed chromatography, by using synthetic macromolecules as fillers in a chromatography in which polyethylene glycol is used as a sample and water as an eluate, and selecting such macromolecules among the mentioned macromolecules that have sample eluting time prolonging behaviors as the temperature rises and that permit separating hydrophilic substances at a high accuracy.  
     CONSTITUTION: A polymerization catalyst and a suspension stabilizer are added to a monomer, such as ethylene glycol dimethacrylate, tetramethylolmethane triacrylate, or ethylene glycol diacrylate. The resulting mixture is subjected to water suspension polymerization as it is agitated, to obtain polymerized particles having a particle size of 5W200 microns. These particles are dried, and the dried particles are dispersed into water to check them as to whether they get wet. Such particles that are wetted with water are collected and used as fillers in a chromatography in which polyethylene glycol is used as a sample and water as an eluate. Among the particles used in this chromatography, particles which have sample eluting time prolonging behaviors as the temperature rises are selected. The polymerized particles thus selected are used as fillers for a high speed liquid chromatography.

IPC: B41J11/20
Filed: 1989-03-30
Abstract: PURPOSE:To print letters even on a thin medium without problems by providing an integral platen at a position different in phase from a dividing platen, and a switching mechanism which retracts said dividing platen from the printing position, and at the same time, advances said integral platen to the printing position. CONSTITUTION:In printing on a thin medium such as a chit, a platen link 7 as a switching mechanism is suitably stretched to a direction A, so that an integral platen 1 is rotated in a direction B. As a result, the integral platen 1 is advanced to the printing position, and simultaneously a dividing platen 2 is retracted to perform printing. At this time, a printing head 9 is retreated in order not to obstruct the rotation of the integral platen 1. In the state where the integral platen 1 is switched to the printing position, the integral platen 1 has a continuous flat surface, without representing steps as the dividing platen 2. Therefore, the thin medium is printed in the flat state, thus preventing unclear printing.
