一般描述
用于农药多残留检测的样品净化。
Carb-GCB/PSA具有与Carb-GCB/NH2相似的保留能力，适合农药多残留检测的样品净化。PSA比NH2,多了一个二级胺基，因而离子交换容量更大，并可作为某些金属离子的络合配体，提供了有别于Carb- GCB/NH2,的选择性。
超薄筛板阻隔，两层填料间流速均匀，可最大限度地除去样品中的干扰物，比Carb-GCB/NH2,更大的保留能力。

Product Introduction:
Sample purification for pesticide multi residue detection.
Carb-GCB/PSA has similar retention capabilities to Carb-GCB/NH2, and is suitable for sample purification for pesticide multiple residue detection. PSA has one more secondary amine group than NH2, resulting in a greater ion exchange capacity, and can be used as a complex ligand for certain metal ions, providing selectivity that is different from Carb GCB/NH2.
Ultra-thin sieve plate barrier, uniform flow rate between the two layers of filler, can maximize the removal of interfering substances in the sample, greater retention capacity than Carb-GCB/NH2.
