Abstract

The present invention aims to provide a liquid chromatography component including a column and a prefilter, which is hard to cause an increase of supplied liquid pressure even when the measurement of a sample is repeated. The present invention is a liquid chromatography component, which includes: a column with filler particles filled therein; and a prefilter, the filler particles having an average particle size in the range of 2 to 20 μm, the prefilter having a filtering particle size in the range of ⅙ to ⅓ of the average particle size of the filler particles.

Claims

exact text as granted — not AI-modified
1 . A liquid chromatography component,
 which comprises:   a column with filler particles filled therein; and   a prefilter;   said filler particles having an average particle size in the range of 2 to 20 μm, and   said prefilter having a filtering particle size in the range of ⅙ to ⅓ of the average particle size of said filler particles.   
     
     
         2 . A liquid chromatography component,
 which comprises:   a column with filler particles filled therein; and   a prefilter,   said column and said prefilter being integrally disposed within a single cylindrical container.   
     
     
         3 . The liquid chromatography component according to  claim 1 ,
 wherein the column and the prefilter are integrally disposed within a single cylindrical container.
