| titleOfInvention |
Stainless steel tubing/frit with sintered inorganic particle, the chromatography comprising it, and their manufacturing method |
| abstract |
This invention is about metal tubing/frit applicable in liquid chromatography and a chromatography column manufactured by using the same. In detail, this invention is about manufacturing the metal tubing/frit by treating a powdered inorganic oxide such as silica, alumina, zirconia, and titania with a strong base, drying it with some humidity included, scrubbing it into powders, putting it in the tip of a chromatographic metal tubing at a proper depth, and by sintering the powders to form a durable sintered frit on the inner wall. n This invention is also about a liquid chromatographic column manufactured by installing the metal tubing/frit's with a sintered end frit at the column inlet and outlet unions and by placing the cylinder-like column main body tubing packed with a stationary phase between the unions. n The metal tubing/frit manufactured according to the description above is not placed inside the column as in the conventional column design, thus it is easily replaced and fixed without disassembling the column, and the column of this design can displace the conventional microcolumn of complicated production process and high cost. |
