A method has been developed for the determination of hexabromocyclododecane (HBCD) in fire proof coatings by gas chromatography-mass spectrometry (GC-MS). The sample was extracted with dichloromethane and purified through an organic membrane before analysis GC-MS. characteristic fragments (m/z 157, 239, 319, 401) quantitative ion 239) were selected. With optimized conditions, good linear relationship obtained between peak area mass concentration HBCD range 5 to 100 mg/L correlation...
The detection of trace levels molecular gases has gained increasing attention in many fields from atmospheric pollution and climate change monitoring to industrial safety breath analysis for clinical diagnosis. Established techniques e.g. mass spectrometry, gas chromatography, electrochemical offer accuracy but are bulky expensive. Apart improving limits (LOD) the number target species, there is a major drive towards system miniaturisation cost reduction order enhance field deployment rapid...
