WitrynaTable 4. Accurate mass measurements of the molecular ions for the main impurities observed in (3S)-3-methylmorpholine. Data obtained by EI and PCI at 60,000 resolution (FWHM at m/z 200). Several impurities were detected in the (3S)-3-methyl-morpholine sample. Proposed tentative impurities identification from the deconvolution software … Witrynaand monitoring m/z 127 and 129 (Figure 1). Assuming equal signal response for the 2 isotopes of I (127 and 129), the optimum cell gas fl ow rate was identifi ed from the rate that gave the lowest background equivalent concentration (BEC) at m/z 129, using the measured 127I sensitivity to calculate the BEC for 129I. The lowest 129I
