系统内的温度和气流可以单独调节。优势：全面的温度控制使分析物能够温和加热，并防止与大气中的氧气发生不必要的反应。分析物从样品基质中特异性分离出来。符合“衬层衬层”原理的紧凑设计可防止分析物的损失或携带，并减少所需的维护量。该系统可以随时进一步扩展。使用热萃取，您可以分析不能用注射器直接注入GC/MS...

采用搅拌棒吸附萃取(SBSE)和热脱附系统(TDU)并结合气相色谱-飞行时间质谱(GC-TOFMS)联用技术分析三种不同产地香荚兰提取物中挥发性成分的方法.通过质谱库检索,保留指数比对,共检测出87个化合物,共有成分主要包括香兰素,愈创木酚,苯甲酸苄酯,(E)-肉桂酸乙酯,(E)-肉桂酸甲酯,乙酸龙脑酯,乙酸桃金娘烯酯,壬酸...
Super-TDU inhibits cell viability and colony formation of GC cell lines MGC-803, BGC-823, and HGC27. In Vivo: Super-TDU (intravenous injection; 50 μg/kg or 500 μg/kg; per day) markedly decreases the sizes, weights of tumors, and YAP target genes in a dose-dependent manner in ...
