Verfahren zur Herstellung einer alkalimetallhaltigen Glasperle zur Verwendung in thermionischen Gaschromatographie-Detektoren |
摘要 |
Alkali metal-containing glass beads for use as sources in thermionic detectors for gas chromatography are manufactured by a method which produces reproducible beads of preselected sizes. A glass tube of the desired composition is reduced to capillary size. A section having the volume of the desired bead is cut from the capillary tube and threaded onto a support wire. It is then melted and caused to coalesce onto the support wire. The resultant bead and a portion of the support wire are then incorporated into the detector. |
