    A novel, small-volume, strong cation-exchange column has been employed as an on-line pre-concentrator for samples introduced to the liquid sampling-atmospheric pressure glow discharge (LS-APGD) microplasma. The column stationary phase was synthesized by a unique microwave-assisted grafting of sulfonic acid g. the discharge gas. Because the electrons in the glow discharge have a kinetic energy distribution ranging from slow to fast ( eV) , electron ionization (EI) may also occur but its contribution to ionic pro- duction is usually much less than the Penning process.

The use of the change in the oscillation frequency of the current of a new atmospheric helium glow discharge for sensitive signal detection for gas chromatography is studied. The effluent of a capillary column is directed into the glow discharge cell perpendicular to the axis of the glow discharge that existed between a platinum anode and cathode.

A stable discharge is obtained when Cited by: 7. The change in the oscillation frequency in the current of an atmospheric helium glow discharge is a sensitive detector for gas chromatography. The response of the detector is in the femtomole and picomole range for nonane and decane.

Their simplicity and economy of construction suggests their use in lecture demonstrations, undergraduate laboratory instruction, and in monitoring preparative column work at the laboratory bench. Originating from the atmospheric-pressure glow discharge (APGD), It is possible also to have gas flowing through the inner capillary in addition to the primary gas flow, but this mode was not employed in this preliminary study.

The capillary column was the first advancement in which stationary Due to the small pressure drop associated with open tube capillary columns, long columns of up to 60m can easily be used. 3 Basic Overview on Gas Chromatography Columns. Short columns of 10m should be used for fast analysis of simple samples.

Evalution of a microwave cavity, discharge tube and gas flow system for combined gas chromatography-atomic emission detection. Anal. A column-sealing tool is provided for use during decoupling of a capillary column from a gas chromatography-mass spectrometry (CG-MS) system.

The column-sealing tool includes an engagement structure for removably securing the column-sealing tool within a high vacuum enclosure of the GC-MS system, at a location between a high vacuum end of a transfer line and a mass analyzer.

Ambient ionization is a form of ionization in which ions are formed in an ion source outside the mass spectrometer without sample preparation or separation.

Ions can be formed by extraction into charged electrospray droplets, thermally desorbed and ionized by chemical ionization, or laser desorbed or ablated and post-ionized before they enter the mass spectrometer.

Mass Spectrometry (MS) detectors are most powerful of all gas chromatography detectors. In a GC/MS system, the mass spectrometer scans the masses continuously throughout the separation.

When the sample exits the chromatography column, it is passed through a transfer line into the inlet of the mass [email protected]{osti_, title = {Atmospheric pressure helium afterglow discharge detector for gas chromatography}, author = {Rice, Gary and D'Silva, Arthur P and Fassel, Velmer A}, abstractNote = {An apparatus for providing a simple, low-frequency electrodeless discharge system for atmospheric pressure afterglow generation.
