The main characteristics, application areas, and usage precautions of GDX-302 filling columns, core information:
Characteristic Dimension GDX-302 Fill Column Details and Tips
Fixed phase GDX-302 (a porous polymer microsphere of styrene divinylbenzene copolymer) has hydrophobicity and certain polarity
Matrix polymer porous polymer is corrosion-resistant and has good thermal stability
Typical specification inner diameter: 2-4 mm
Length: 1-3 meters
Particle size: 60-80 mesh or 80-100 mesh. Specific specifications need to be selected according to analysis requirements
The maximum operating temperature is usually ≤ 250 ° C. The actual operating temperature should be lower than the decomposition temperature of the stationary phase, and the tolerance of the instrument should be considered
Polymer matrices generally have a wider pH tolerance range than silicone matrices
Mainly used for gas chromatography analysis, it is suitable for the separation of polar or polarizable compounds such as water, alcohols, aldehydes, ketones, acids, esters, amines, nitriles, etc. It is particularly suitable for the analysis of trace amounts of water in organic matter. When selecting a chromatographic column, it should be determined based on the properties of the analyte
Characteristics: Large column capacity and high quantitative accuracy
Less tailing for hydroxyl containing compounds such as water and alcohols
corrosion-resistant
The packed column can be used for analyzing active substances and has unique applications in fields such as gas analysis and trace water analysis
Precautions: Aging treatment is required before use
Note that a decrease in column efficiency and a deterioration in peak shape may be signs of a decrease in column efficiency
Proper storage (such as blocking both ends of the column to avoid fixed phase contamination and moisture absorption)
Name: Stainless Steel Filled Column
Model: GDX-302
Specification: 2m * 4MM, 60-80 mesh
Operating temperature: 240 ° C
Application: Suitable for polar or polarizable compounds such as water, alcohols, aldehydes, ketones, acids, esters, amines, nitriles, etc
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "GDX-302 Filled Chromatography Column Application Thermo Fisher Scientific 1300": suitable for the separation of polar or polarizable compounds such as water, alcohols, aldehydes, ketones, acids, esters, amines, nitriles, etc., especially for the analysis of trace amounts of water in organic compounds.
