Stable chlorine isotope ratio analysis of subnanomolar level methyl chloride by continuous-flow isotope ratio mass spectrometry
stable chlorine isotope ratio continuous flow isotope ratio mass spectrometry methyl chloride
2017/4/11
An analytical system using continuous-flow isotope ratio mass spectrometry (CF-IRMS) was developed to determine
the stable chlorine isotope ratios (δ37Cl) for CH3Cl. By using appropriate devices for ...
Methyl halide production by cultures of marine proteobacteria Erythrobacter and Pseudomonas and isolated bacteria from brackish water
Methyl halide production proteobacteria Erythrobacter
2014/4/4
Bacteria were investigated for the production of methyl chloride, methyl bromide, and methyl iodide from
brackish water. Bacteria were isolated and incubated at 25uC, and the concentrations of methyl...
