Tsingcarbo O: Novel GC Packing Solves Oxygen Adsorption Problem of Polymeric Materials

In gas chromatography (GC) analysis, conventional porous polymer packings (e.g., Porapak Q) may present a limitation when analyzing low-concentration oxygen: oxygen adsorption. This issue distorts analytical results, especially in trace oxygen detection where precision is paramount.

The Root Cause of Oxygen Adsorption

The problem stems from the free radical polymerization process used to manufacture traditional packings. Residual free radicals with high reactivity readily trap oxygen molecules (·Ō≡Ō·) via radical addition reactions, forming stable oxygen adducts.

Compounding this issue, porous polymers have large specific surface areas and complex pore networks. Residual free radicals exist deep within pores and continuously migrate to the surface due to the skin effect. Even surface passivation (e.g., high-temperature aging, chemical treatment) fails to address the root cause, as internal free radicals replenish surface sites over time. This leads to persistent oxygen adsorption, resulting in underestimated or undetectable low-level oxygen in analysis.
