摘要:

利用AMI-MS(Ambient Ionization-accurate Mass)质谱技术,检测和识别食品包装不可见背面粘脏化合物,并识别基本组分。结果表明,AMI-MS 可在不进行任何样品处理的条件下,直接测得其背面粘脏化合物的成分,而且可以通过质谱对其化合物结构进行确认,相比常用的GC-MS 法,具有简便、快速、准确、便于高通量分析等优势。

Abstract:

Invisible set-off compounds from print in reverse side of food packaging was detected and identified using ambient ionization-accurate mass spectrometry (AMI-AMS). The result showed that AMI-AMS is able to detect print set-off and identify different compounds without any pretreatment of sample; the structure of the compounds detected can be confirmed using gas chromatographic-mass spectrometric (GC-MS) analysis; compared with GC-MS, AMI-AMS has the advantages of simple, fast, accurate, and convenient for high throughput analysis.

Key words: set-off AMI-AMS GC-MS
