Main application areas
GDX-301 filled column is particularly suitable for the following analysis due to its characteristics:
The determination of trace moisture in organic matter: This is its most classic and widely used application. Water is weakly retained on the GDX-301 column and flows out first, which can be well separated from most organic solvents (such as alcohols, ethers, hydrocarbons) for accurate quantification.
Separation of permanent gases and light hydrocarbons: such as H ₂, O ₂, N ₂, CO, CO ₂, CH ₄, C ₂ H ₄, C ₂ H ₆, C ₂ H ₂, etc. It is commonly used in the fields of chemical engineering, petroleum and natural gas, and air separation to analyze these gas mixtures.
Analysis of low molecular weight polar compounds, such as methanol, ethanol, acetone, formic acid, acetic acid, etc.
Separation of some isomers: for example, isomers of xylene can also be separated under certain conditions.
Stainless Steel Packaged Column:
Material: Stainless steel (usually 304 or 316 model).
Advantages: High mechanical strength, very sturdy and durable, not easy to break, able to withstand high column front pressure. The price is relatively cheap.
Disadvantages: Some active compounds (such as amines, unsaturated hydrocarbons, and some sulfur-containing compounds) may have catalytic activity or adsorption, leading to peak tailing or sample decomposition. The inner wall is not as smooth as glass or fused silica.
Specification: Typically, the outer diameter is 1/8 inch (3.175mm) or 1/4 inch (6.35mm), and the length is generally 1 meter, 2 meters, or 3 meters.
Name: Shimadzu Stainless Steel Filled Column
Model: GDX-301
Specification: 2m * 4MM, 60-80 mesh
Maximum operating temperature: 240 ° C
Application: Gas chromatography analysis of acetylene hydrogen chloride, sulfides (such as H ₂ S, COS), and some high boiling point compounds, and able to tolerate certain moisture
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "GDX-301 Column Application Shimadzu GC2010" GDX-301 packing material, which has outstanding performance in the following aspects:
Acetylene and hydrogen chloride analysis: This is one of its classic applications.
Sulfide analysis: For example, hydrogen sulfide (H ₂ S) and carbonyl sulfide (COS) in water gas can obtain reproducible and accurate results even if the sample contains water.
Analysis of substances with higher boiling points.
Good water resistance, can be used for analysis of some water containing samples
GDX-301:
类型： 这是一种高分子多孔微球固定相，属于聚合物固定相（通常是苯乙烯-二乙烯苯的共聚物）。
特点：
非极性： GDX系列中，GDX-301属于弱极性或中等极性（相较于GDX-101/102等非极性型号）。
多孔结构： 具有均匀的孔结构和较大的比表面积，分离机理基于尺寸排阻和吸附作用。
热稳定性好： 最高使用温度通常可达250°C左右。
憎水性： 对水分子吸附性弱，水峰出峰早且峰形尖锐。
主要应用领域
GDX-301填充柱因其特性，特别适用于以下分析：
有机物中微量水分的测定： 这是其最经典和广泛的应用。水在GDX-301柱上保留很弱，先流出来，可以与大多数有机溶剂（如醇类、醚类、烃类）很好地分离，从而准确定量。
永久气体和轻烃的分离： 如H₂, O₂, N₂, CO, CO₂, CH₄, C₂H₄, C₂H₆, C₂H₂等。在化工、石油天然气、空分等领域常用于分析这些气体混合物。
低分子量极性化合物的分析： 如甲醇、乙醇、丙酮、甲酸、乙酸等。
一些异构体的分离： 例如，二甲苯异构体在一定条件下也能得到分离。
不锈钢填充柱 (Stainless Steel Packed Column):
材质： 不锈钢（通常是304或316型号）。
优点： 机械强度高，非常坚固耐用，不易折断，能承受较高的柱前压。价格相对便宜。
缺点： 对某些活性化合物（如胺类、不饱和烃、一些含硫化合物）可能具有催化活性或吸附性，导致峰拖尾或样品分解。内壁光洁度不如玻璃或熔融石英。
规格： 通常外径为1/8英寸（3.175mm）或1/4英寸（6.35mm），长度一般为1米、2米或3米。
