Adscientist IGC设置允许非常灵活地注入15种以上的分子探针。以无限稀释(IGC-ID)或以饱和表面,随后的解吸附分析的有限浓度(IGC-FC)进行样品的特征分析。
使用IGC-ID,测定了新鲜、使用过、人工老化和再循环催化剂的非极性和极性相互作用。用IGC-FC测定了分子筛对甲醇的吸附行为,包括表面吸附能分布。使用IGC装置,可以通过零长柱(ZLC)轻松量化氧化铝珠中的扩散系数。
A novel IGC setup allows a very flexible injection of 15+ molecular probes at either infinite dilution (IGC-ID) or a saturation of the surface by a finite concentration (IGC-FC) and subsequent desorption analysis.Using IGC-ID, the apolar and polar interactions of fresh, used, artificially aged and recycled catalysts were determined.By IGC-FC the adsorption behaviour of zeolites by methanol was measured including adsorption energy distribution.Diffusion coefficients in alumina beads could easily be quantified by Zero Length Column (ZLC) using the IGC setup.
