分析仪器脉冲抽提二次离子质谱仪脉冲抽提二次离子质谱仪应用于检测样品最上面分子层的化学成份。很多材料如塑料、橡胶、陶瓷、生物聚合物、颜料、油漆都不是电的良导体而且在传统的SIMS分析中积累静电荷。使得分析工作变得困难。而这个系统以每秒20次的速度交替抽提正、负离子以避免静电荷的积累。 Idaho National Engineering Laboratory(DOC) 测量分子量的新途径为生物化学分析而设计的激光系统能迅速、准确地测定肽、蛋白质、碳水化合物及其它高分子材料的分子量。此项技术是使用很少量的样品在基体辅助激光解吸时间飞渡质谱仪的基础上实现的。该系统在帮助科学家们表征蛋白质、检验合成肽以及提供酵素消化(溶
Analytical Instruments Pulsed Extraction Secondary Ion Mass Spectrometry Pulsed Extraction Secondary Ion Mass Spectrometry is used to determine the chemical composition of the uppermost molecular layer of a sample. Many materials such as plastics, rubbers, ceramics, biopolymers, pigments, paints are not good conductors of electricity and build up static charge in traditional SIMS analysis. Make the analysis difficult. This system alternately extracts positive and negative ions at a rate of 20 times per second to avoid the accumulation of electrostatic charges. Idaho National Engineering Laboratory (DOC) A New Way to Measure Molecular Weight The laser system designed for biochemical analysis quickly and accurately determines the molecular weight of peptides, proteins, carbohydrates and other polymer materials. This technique is based on the Femtosecond mass spectrometer with matrix-assisted laser desorption time using a very small amount of sample. The system helps scientists characterize proteins, test synthetic peptides, and provide enzymes for digestion
