摘要
A simultaneous and quantitative analysis of 5 elements including sulfur, fluorine, chlorine, bromine and iodine in pharmaceutical compounds was studied using a XS-2100H elemental analyzer. Anomalous values were obtained in the analysis of bromine and iodine in sulfur containing compounds using the XS-2100H elemental analyzer in the factory default made. We focused on the gas trap tube to fall to the normal values of bromine and iodine. Highly accurate analytical results were obtained by improving the XS-2100H elemental analyzer with our invented device.
