Beschreibung

General description

Methyl acetate is an acetate ester, classified as a volatile organic compound (VOC). It is used as a solvent for many resins and oils.

Application

The analytical standard can also be used as follows:

• Quantitative analysis of seven volatile organic compounds (VOCs) in paint coating samples by dynamic headspace-gas chromatography-mass spectrometry (D-HS-GC-MS)
• Detection of 88 VOCs in breath samples of lung cancer patients using solid-phase microextraction (SPME) combined with GC-MS
• Development of a thermal desorption-gas chromatography-mass spectrometry (TDS-GC/MS) based method for the identification of very volatile organic compounds (VVOCs) in indoor air samples
