The design of GDX-303 enables it to have good separation effects on certain specific compounds:
Sulfide analysis: This is the most prominent and widely used field of GDX-303. It can effectively separate and determine various sulfides, such as hydrogen sulfide (H ₂ S), carbonyl sulfide (COS), carbon disulfide (CS ₂), and sulfur dioxide (SO ₂). For example, for the analysis of trace amounts of hydrogen sulfide (H ₂ S) and carbonyl sulfide (COS) in coal gas and coke oven gas, the detection limit can reach 1mg/Nm ³.
Other gas analysis: In addition to sulfides, GDX series fillers (including GDX-303) can also be used for the separation of permanent gases (such as CO, CO ₂) and low-carbon volatile organic compounds (C1 to C3 hydrocarbons).
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "GDX-303 Filled Chromatography Column Application Shimadzu GC2014": GDX-303 is a unique chromatographic packing material, particularly adept at analyzing various sulfides. If you need to detect sulfur-containing gases such as H ₂ S, COS, CS ₂, SO ₂ in your work, GDX-303 would be a worthwhile choice to consider. When in use, as long as you pay attention to details such as aging and carrier gas deoxygenation, it can provide you with reliable analysis results.
