Miniaturized sample preparation combined with liquid phase separations

Journal of Chromatography A, 2003
Miniaturized sample preparation methods designed as the sample pretreatment for liquid phase separations, such as liquid chromatography, capillary electrophoresis and capillary electrochromatography, have been reviewed especially for the on-line coupling of the sample preparation process and the separation process.

Preparation and Separation of DNA‐Wrapped Carbon Nanotubes

Current Protocols in Chemical Biology, 2015
AbstractPurification of single‐chirality single‐wall carbon nanotubes (SWCNTs) from their synthetic mixture is a prerequisite for many applications. DNA‐controlled carbon nanotube (CNT) purification has evolved over a decade along with other separation techniques utilizing different types of dispersing agents such as surfactants and polymers.

Preparative particle separation in density gradients

Quarterly Reviews of Biophysics, 1968
The purpose of this review is to summarize the present status of preparative zonal centrifugation and to indicate where the remaining problems, in the reviewer's opinion, may lie. The field is sufficiently new for interest in practical separartions to be uppermost.

Combined continuous and preparative chromatographic separation

Journal of Chromatography A, 1995
A combined continuous and preparative gas-liquid chromatographic system was considered for the separation of the close-boiling components diethyl ether and dichloromethane. The characteristics of the combined continuous and preparative gas-liquid chromatographic system were investigated in terms of the experimental operating conditions.
