Abstract
This invention is directed to a unitary one-piece sample mini-column for a cassette chemical immobilization and treatment system for enabling the performance of various complex chemistries. The cassette assembly comprises a plurality of analyte sample columns ('mini-columns'), reagent wells containing pre-packaged reagents including powdered, microencapsulated, liquid or lyophillized reagents, analyte loading funnels, alignment mechanisms for the analyte sample columns, and a machine readable instruction code set for identfying a chemical treatment protocol. The mini-columns are improved columns having a high pressure interface capability to permit direct insertion of the mini-column into a high-pressure solvent line for use as a support column for HPLC analysis. The same chemistries may be performed at all sample mini-column addresses, or a separate, completely independent set of protocols may be defined for each address, or for each block of addresses pursuant to the instructions contained in the machine readable code on the cassette.
