產(chǎn)品描述
General description
助留機理:正相和陰離子交換
樣品基質(zhì)相容性:有機或含水溶液
• 聚合鍵合的乙二胺-N-丙基相,同時含有伯胺和仲
- pKa 為 10.1 和 10.9 的弱陰離子交換劑
- 就選擇性而言,與氨丙基固相萃取相 (NH2) 類似,但由于存在仲胺(0.98-1.05 毫當(dāng)量/克),所以容量更大
- 當(dāng)進(jìn)行食品中的多殘留殺蟲劑分析時,其強親和性和高容
量可用于去除脂肪酸、有機酸和一些極性色素及糖類 - 該產(chǎn)品可降低食品氣相色譜分析過程中出現(xiàn)的基質(zhì)增強效
應(yīng)的影響 - 通過 GC-FID 和 GC-MS 測試其出色的凈化效果
- 配體的雙齒性質(zhì)可用于螯合
