Latest Patents

Semerdjian's latest patents include a bonding procedure for silica assemblies and a rigid silica capillary assembly. The bonding procedure for silica assemblies introduces a method that utilizes a mixture of ultrasonically treated silica powder and a suspension liquid. This innovative bonding material is applied to the surfaces of silica components, dried, and then heated. The result is a solid bond that minimizes localized heating, preventing distortion of the silica components during the bonding process.

The rigid silica capillary assembly is another significant invention. This tubular assembly is particularly adaptable for use in capillary columns in gas chromatography. It consists of a capillary that is wound around and fused to a hollow mandrel, which is then stress-relieved by heating. This design enhances the rigidity and fracture resistance of the assembly compared to previously available columns. Additionally, the assembly can accommodate solid, brittle stationary phases due to its structural strength.
