Creative BioMart Chromatography provides professional high precision custom silica capillary tubes services. Silica capillary tubes are the essential components and required materials of the gas chromatography (GC), high-performance liquid chromatography (HPLC), high-performance capillary electrophoresis chromatography (HPEC) and microfluidics systems.The fused silica capillary columns for gas chromatography (GC) was an important technological invention in the twentieth century. The advent of silica capillary columns not only revolutionized GC, but also gave birth to new separation technologies - capillary electrophoresis (CE), capillary LC and capillary electrochromatography (CEC). Silicon-based columns have tremendous advantages over the previous borosilicate technology and have become the accepted standard more quickly than is characteristic of new equipment in analytical chemistry.
To make the silica capillary more rugged, a polyimide surface coating is used to protect the outer surface. If the polyimide layer is covered by a more fully cured layer before it is fully cured, bubbles or blisters may form when the succeeding layer is heated during curing due to rapid evaporation of the trapped water of imidization, residual solvents and the volatile monomer contaminants. These blisters are tiny regions of extremely thin polyimide that are easily oxidized at the operating temperature of the gas chromatographic column. The bubbles in the column are very vulnerable to physical damage. The silica capillary tubes produced by Creative BioMart Chromatography completely prevent the formation of bubbles or blisters through a well-controlled manufacturing process. In addition, with the lump-detection mode of the laser micrometer, even a very small defective of capillary are selected and discarded.
