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-modified1 - 3 . (canceled)
4 . A method for assaying blood samples comprising,
applying a blood sample to 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, wherein the blood sample is assayed.
5 . The method according to claim 4 ,
wherein the column and the prefilter are integrally disposed at a substantially zero distance.Cited by (0)
