Abstract
A porous layer open tubular (PLOT) column includes capillary tubing; one or two particle traps disposed inside one or two end sections of the capillary tubing; and a stationary phase comprising a porous or non-porous material coated inside a main section of the capillary tubing. A method for preparing a porous layer open tubular (PLOT) column includes preparing one or two particle traps inside one or two end sections of a capillary tubing; and preparing a stationary phase comprising a layer of a porous material coated inside a main section of the capillary.

A porous layer open tubular (PLOT) column, comprising:
- a capillary tubing;
- two integrated particle traps disposed inside two end sections of the capillary tubing;
- and
- a stationary phase comprising a porous layer coated inside a main section of the capillary tubing,
- wherein there is no connector between the capillary tubing and either of the two integrated particle traps.
A method for preparing a porous layer open tubular (PLOT) column, comprising:
- preparing two integrated particle traps inside two end sections of a capillary tubing;
- and
- preparing a stationary phase comprising a porous layer coated inside a main section of the capillary,
- wherein there is no connector between the capillary tubing and either of the two integrated particle traps.
A method for preparing a porous layer open tubular (PLOT) column having two integrated particle traps disposed at the two end sections, comprising:
- stripping a first section of a stationary phase coating from a first end of a PLOT column;
- preparing a first particle trap in the stripped first section;
- stripping a second section of a stationary phase coating from a second end of a PLOT column;
- and
- preparing a second particle trap in the stripped second section,
- wherein there is no connector between the capillary tubing and either of the two integrated particle traps.
