赛默飞 ISQ EC单四极杆质谱

利用双三元在线除盐技术，在保留原一维不挥发性流动相的基 础上，对样品中的主化合物及杂质进行分离，达到较好的分离 度，结合二维色谱柱切换技术实现在线脱盐，二维采用质谱兼 容性流动相，将收集环中馏分脱盐后转入质谱，通过去卷积软 件处理采集数据，可以了解寡肽样品电荷分布范围及其分子 量。该方法重现性良好，自动化程度高，值得推广

present data, and to our understanding is far better than any other software package ... With the Chromeleon Reports, we are seeing time and cost savings saving equivalent to four to five full time employees depending on the workload in each month. These savings are higher than anticipated.” Bernd Boscolo QC Improvement Projects Team Leader and CDS Administrator Douglas Manufacturing Ltd. Auckland, New Zealand Bernd Boscolo received an Engineering Diploma in chemistry from the University of Applied Sciences, Isny, Germany. He worked for more than three years at privately held pharmaceutical manufacturer Swiss Caps AG, Kirchberg, Switzerland before joining Douglas Manufacturing eight years ago. In his most recent position as QC Improvement Projects Team Leader, Bernd oversees Chromeleon CDS operation in his company’s Quality Control and New Product Development laboratories. His duties include the design and validation of Chromeleon Report Templates.

本标准规定了动物源食品中甲苄喹啉和癸氧喹酯残留量的液相色谱质谱／质谱测定方法。 本标准适用于鸡肉、鸡肝、鸡肾、鸡蛋、牛肝和牛奶中甲苄喹啉和癸氧喹酯残留量的测定和确证。

The results presented demonstrate the successful development of an accurate, precise, and selective SPE-LC-MS/MS method for the analysis of desmopressin from human plasma. Use of micro-elution SPE allowed for concentration of the sample prior to analysis without the need for post-extraction processing. Utilizing SOLAµ mixed-mode SPE provided both a clean and repeatable extract across the concentration range.
