Abstract
The present invention provides a method and apparatus for fraction collection from a chromatographic system. One or more substances of interest from a sample are collected in high concentration with high efficiency.
Claims22
A method for fraction collection from a chromatographic system comprising:
- a. A means of penetrating a septum of a collection means;
- b. Means of introducing one or more substances of interest in a reduced pressure stream fluid through an inner needle;
- c. Means for removing a reduced pressure compressible fluid through an outer needle around the inner needle;
- d. Collecting one or more substances of interest and any solvent.

An apparatus for fraction collection from a chromatographic system comprising of:
- a. A stream of one or more substances of interest in one or more compressible fluids;
- b. A detector for detecting said substances of interest in said stream;
- c. A pressure regulating means for reducing the pressure of said stream;
- d. At least one valve for directing said reduced pressure stream to a waste collection means or fraction collection means;
- e. At least one collection means for collecting said one or more substances of interest from said reduced pressure stream;
- f. A needle assembly including an inner needle for introducing said reduced pressure stream into said collection means and an outer needle for removing said one or more reduced pressure compressible fluids.
