Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A liquid chromatography component, which comprises: a column with filler particles filled therein; and a prefilter; wherein the prefilter is located on the upstream side of the column, wherein the prefilter and the column are joined via a joint pipe, wherein the filler particles have an average particle size in the range of 2 to 20 μm, and wherein the prefilter has a filtering particle size in the range of ⅙ to ⅓ of the average particle siz…
