Adsorbents for TLC Adsorbents for coating TLC plates

302 This chapter gives a detailed description of the adsorbents manufactured by MACHEREY-NAGEL for coating of TLC plates. Especially for quantitative investigations, however, we recommend our ready-to-use layers with these adsorbents, since production of high-quality homogeneous layers for reproducible separations requires intense practical experience in coating techniques, which today is not a...

A Plasma Reactor for Solid Surface Modification

A general purpose plasma reactor has been designed and built to be used in various fields such as metallurgy, and microelectronics. The important aspects of the system design are : (a) the chamber can be evacuated to a base pressure of approximately 5 X 10-7 Tom; (b) capabilities for thermal bake out at 150°C, and nitrogen pre-burn at a pressure of about 3 X 10-3 Torr; (c) substrate holder whic...

Investigation of the Effect of Plasma Polymerized Siloxane Coating for Enzyme Immobilization and Microfluidic Device Conception

This paper describes the impact of a physical immobilization methodology, using plasma polymerized 1,1,3,3, tetramethyldisiloxane, on the catalytic performance of β-galactosidase from Aspergillus oryzae in a microfluidic device. The β-galactosidase was immobilized by a polymer coating grown by Plasma Enhanced Chemical Vapor Deposition (PEVCD). Combined with a microchannel patterned in the silic...
