鄭州寶晶電子科技有限公司 濾膜

一. 應(yīng)用：

微孔濾膜廣泛應(yīng)用于樣品分析和實(shí)驗(yàn)室樣品過(guò)濾中。

二.分類(lèi)：

1.水系濾膜：混合纖維素酯膜（水系濾膜）由硝酸纖維素酯和醋酸纖維素酯制成，是一種多孔性的精密過(guò)濾材料，濾膜表面孔徑分布均。相比較于硝酸纖維膜，其一致性和表面的光滑程度都要更好。此類(lèi)膜經(jīng)典應(yīng)用于溶液中懸浮微粒的粒子計(jì)數(shù)和分析。

2.有機(jī)系濾膜：尼龍膜（有機(jī)系濾膜）材質(zhì)強(qiáng)韌，適用于HPLC中的大部分溶液（如酒精）過(guò)濾，尤其對(duì)氣體凈化和微粒重量分析有獨(dú)到之處。
Membrane is widely used in analytical and laboratory filtration. Mixed cellulose ester membrane(for hydrophilic) is a mixture of cellulose acetate and cellulose nitrate. It is a porous delicate filtering material and the pore evenly distribute on the membrane surface, provides a more uniform and smoother surface compared to pure nitrocellulose membrane. This membrane is typically used to count or analyze particles contained in liquids or captured from aerosols. Nylon membrane(for hydrophobic) is strong and compatible with a broad range of aqueous solution including alcohols and solvents used in HPLC work. It is suitable for air decontamination and particles analyze.
