MS数据处理软件鉴定复杂样品中痕量化合物

Identifying Trace Compounds in Complex Mixtures With MS Data-Processing Software

为了跟随全球规则,许多行业(例如,建筑业和装饰,机动类和电子)产品释放的挥发性有机化合物(VOCs)需要进行监测。检测VOC的经典方法是热解析(TD)-气相色谱-质谱(GC-MS)联用。对于非科学家来说,该方法产生的复杂数据令人生畏,难以解释而且比较耗时。为了解决这个问题,这里设计了一种特殊软件,可以从复杂的GC-MS数据中方便地鉴定目标化合物,如产品辐射图中的目标组分。

In order to comply with global regulations,many industries （e.g.,construction and decorative products,automotive,and electronics） are required to monitor the levels of specific volatile organic compounds （VOCs） emitted from their products. Analysis of VOC emissions is typically performed by thermal desorption （TD） with GC-MS. To a nonscientist,the complex data yielded can be daunting,and interpretation too difficult and time-consuming. To address this,software has been developed specifically to simplify identification of target compounds in complex GC-MS data such as product emission profiles.
