不規(guī)則硅膠層析色譜填料
不規(guī)則硅膠層析色譜填料大多為裸硅膠，是最傳統(tǒng)的，經(jīng)濟(jì)性高，工業(yè)規(guī)模化應(yīng)用常壓低壓中最合適的色譜層析填料，請根據(jù)實(shí)際情況選擇各項(xiàng)指標(biāo)參數(shù)。
?關(guān)鍵指標(biāo)：
顆粒度（外在形態(tài)、粒徑密度大小分布等）；
孔徑（如比表面、孔容相關(guān)內(nèi)在指標(biāo)）。
這兩項(xiàng)的選擇最為重要，會直接影響色譜應(yīng)用中如壓力、保留值、收率、純度和效率等生產(chǎn)關(guān)鍵因素。

Silica Gel Column Chromatography
Column chromatography is the ideal method of chromatography for purification and separation. It is a technique in which the stationary phase is solid adsorbents like silica gel is a liquid. The principle of active compound separation depends on the activity of adsorbents and polarity of the solvent. If the polarity of the solvent is very low and the activity of the adsorbent is strong and high, then result of separation of compound is good. On the other hand, if the polarity of the solvent is very high and the activity of adsorbents is high then it gives poor results of compound separation. It means purification and isolation of compounds are not 100% pure.

The process of column chromatography is the oldest and the most common technique f or the separation of complex mixtures packed in a column. Chromatography is a technology by which a mixture of chemicals are separated by its components between two phases like stationary phase which is remain fixed in placed using two adsorbents such as silica gel and activated alumina, while as mobile phase is another method which is slowly movable and flows down through the column by either gravitational forces or external pressure into the column. The Stationery phase may be solid or liquid and the mobile phase is always in solid liquid foam use different solvents.

Analytical Chromatography: The collectively term of chromatography is may be analytical or preparative. The starting phase of chromatography is analytical chromatography with little amount of silica gel mesh 60-120 size by using analytical column packaging, to analysis how many percentage of mixture is purify. Analytical chromatography is a simple method of chromatography with faster and cost effective separation. In analytical chemistry development, techniques for solving chemical subtracts by using thin layer plates coated silica gel on glass plate. This technique becomes standa
