ABSTRACT:
Chromatographic separation devices include multiple batch-processed columns joined by a body structure and adapted to perform parallel analyses. Both slurry-packed and monolithic column embodiments are provided. One or more liquid-permeable frits of various types may be used to retain stationary phase material within columns. A fluidic distribution network may be used to distribute stationary phase material and/or mobile phase solvents to multiple columns. Separation devices, including microfluidic embodiments, may be fabricated with various materials including polymers. Multi-column fabrication and separation methods are provided.
