Abstract:
The present invention relates to an analysis system capable of online transferring an analysis sample and promptly acquiring an analysis result. The analysis system capable of analyzing the analysis samples supplied from at least two sites, with one analysis apparatus, and requiring no cleaning process for a nebulizer and a spray chamber, is provided. The present invention relates to analysis system including at least two sample individually transferring units. Each sample transferring path of the sample individually transferring units is coupled to a plasma torch of a common analysis unit including the one analysis apparatus with inductively-coupled plasma or microwave plasma. Each sample transferring path has a main flow path, a makeup gas supply path, and a drain flow path. The plasma torch has a sample introducing pipe that introduces the atomized analysis sample, provided at a substantially center. The inner diameter of the drain flow path is equivalent to or larger than the inner diameter of an inlet portion of the sample introducing pipe of the plasma torch.
