Abstract
A protected fused-silica capillary liquid chromatography (liquid chromatography) column is shielded inside a single flexible tubing, which has the same length as the capillary and is integrated with the capillary in the packing process. The column has the advantages of a fused-silica capillary liquid chromatography column combined with the benefits of the shield tubing which makes the column more accurate, durable, and convenient to use, and less expensive to produce.
