To provide a liquid chromatography member with a column and prefilter, which is less susceptible to an increase in liquid passage pressure after repetitive measurement of a specimen.SOLUTION: A liquid chromatography member is provided, having a column filled with filler particles and a prefilter. The filler particles have an average particle diameter of 2-20 μm, and the prefilter has a filtration particle size that is 1/6 to 1/3 of the average particle diameter of the filler particles.SELECTED DRAWING: Figure 1 【課題】カラムとプレフィルタとを有する液体クロマトグラフィー用部材であって、検体の測定を繰り返しても、通液圧力上昇が生じ難い液体クロマトグラフィー用部材を提供する。【解決手段】充填剤粒子が充填されたカラムと、プレフィルタとを有する液体クロマトグラフィー用部材であって、前記充填剤粒子は、平均粒径が２〜２０μｍであり、かつ、前記プレフィルタは、濾過粒度が前記充填剤粒子の平均粒径の１／６〜１／３であることを特徴とする液体クロマトグラフィー用部材。【選択図】図１
