Solid-phase Submonomer Synthesis of Peptoid Polymers and their Self-Assembly into Highly-Ordered Nanosheets

1-18 and 120 minutes for residue 19-36. t-Butyl beta-alanine HCl was converted to the free base (see discussion) whereas phenethylamine and boc-ethylenediamine were both used directly. The resin was cleaved with 95% TFA, 2.5% triispropylsilane

一次解吸直接进样法用于室内大气TVOC分析方法的研究

吸管热解吸后分析，解吸管不进行反吹活化，继续进行再次热解吸进样分析，记录每次进样的分析的结果，将第一次热解吸的峰面积除以总的热解吸的峰面积即为热解吸率。见表5的测定结果，由表5可以看出，热解吸率除苯以外，均在95%以上。表4.热解吸率的的测定（1） 浓度：1mg/ml实验组分名称 空管（单位：mv。s） Tenax-TA（单位：mv。s） 热解吸率%苯 15.9 15.8 99.4甲苯 27.0 31.3 11.5.7乙苯 36.6 40.2 109.6对间二甲苯 81.7 88.7 108.5邻二
