尊敬的各位老师：
您好，很久未有质谱信息速递，您是否有点想念呢？请看看今天我们会给您带来什么样的惊喜！
会议预告：
2014年5月4日至7日，DART（实时直接分析质谱）宣传的足迹将抵达有着丰厚历史遗址的美国得克萨斯州南部城市-圣安东尼奥市，参加即将开幕的AOCS（美国石油化学家大会）会议。与会期间科学家们将展示如何利用DART技术快速检测重油、和食用油成分及质量，IonSense公司的Brian Musselman博士将在周三的分析会场演讲DART质谱新技术及应用。
欲了解AOCS会议DART的演讲内容，请联系我们或请继续关注我们后续的精彩信息传递。
We would like to let you know about two presentations at the upcoming AOCS meeting in San Antonio May 4-7, showing how our Direct Analysis in Real Time Mass Spectrometry (DART MS) system can be utilized for rapid determination of edible oil composition and quality. In separate presentations Brian Musselman of IonSense, and Susan Seegers, of Bunge NA, will be speaking about methods for using our DART MS technology in Wednesday morning's Analytical session Please contact me to set up a time to talk at the AOCS Conference May 4-7th or follow up at your convenience to learn more about DART MS for your applications. Thanks.
Regards,
Brian Musselman

Abstract: Nutritional supplements incorporate a wide variety of plant materials. Some supplements are single plant but often different tea leaves and even chemicals are added to produce products with the desired composition. As the quality control of these materials must improve with new regulations the need for relevant chemical test increases the burden on small manufacturers and exporters. We have completed analysis of a wide variety of medicinal supplements utilizing Direct Ionization in Real Time ambient ionization mass spectrometry. The method provides an easy means to complete chemical analysis with little sample prep. During these investigations we have been able to generate lipid profiles for the triglycerides in just seconds per sample. Statistical analysis of the data can be used to determine the presence / absence of different plant materials. The method affords a rapid means to check for sample composition and even quality as detection of irregular lipid profiles is made possible even when small concentrations of lipids are present as in the case of dried leaves.
摘要：
营养补品中包含了多种多样的植物体：有些补品虽只含有单株植物，但其成品中通常也会加入不同的茶渣、甚至化学品和其他所需成分。随着相关化学检验新规的出台，这些原材料的质量控制变得更加严格，相应地，这也会增加小型制造商及出口商的负担。令人振奋的消息是，我们已经用实时直接分析（DART）质谱法成功地完成了一系列药物性补品的快速检测。此法简单易操作，几乎不需样品制备即可完成化学分析。我们经过多次实验研究，确保每个样品只需几秒就能够生成甘油三酸酯的油脂谱图，得出的数据经统计分析后即能确定不同植物体的存在。这种方法让我们能够快速识别鉴定样品成分和质量，甚至能检测出干叶中低浓度油脂的不规则的油脂谱图。

Identification of Lipid Oxidation Products Using SPME-DART-QTOF

Abstract: Typically, a variety of gas chromatography (GC) methods have been used to evaluate oxidation products in edible oils. There are many different ways to introduce the sample into the GC such as cold-trapping, gas sampling, and more recently, solid-phase microextraction (SPME). Coupled to a mass spectrometer, these methods can concentrate, separate, and identify oxidation products. Direct analysis in real time (DART) is an ambient ionization technology used to introduce samples into a mass spectrometer. When used in conjunction with a quadrupole time of flight (QTOF) mass spectrometer, samples can be quickly analyzed with high mass accuracy. This methodology was applied to oxidation products in edible oils. Because these oxidation products are in low concentrations, SPME was also employed to concentrate the volatiles and used in conjunction with the DART. The SPME fiber was then directly desorbed in the DART stream and the oxidation products introduced into the QTOF.
摘要：
通常，我们已经习惯了使用各种气相色谱分析方法来评估食用油的氧化产物，多种多样的进样方式如冷捕集、气体取样以及最新的固相微萃取，再结合质谱仪，就能浓缩、分离以及鉴定氧化产物。DART（实时直接分析）质谱运用原位电离技术来进行样品进样，当其与飞行时间质谱连接后能迅速且以高质量精度地分析出样品，此种方法曾经应用于食用油的氧化物鉴定，同时由于氧化产物浓度较低，固相微萃取（SPME）可用来浓缩富集挥发性组分。固相微萃取纤维直接被DART气流解离，氧化产物继而脱附并离子化，进入QTOF质谱系统检测分析。
