Highly accurate constructionLower running costs than 1-piece torchesUsually comprises a quartz torch body, a torch adaptor, an injector andGazFit connectors. All these parts are replaceable, making the semidemountable torch more cost effective than the fixed quartz torch.Essentially the design of the torch for standard analyses and HF analyses isthe same, with the exception of the injector material. The torch for aqueousand organics analyses comes with a quartz injector, while the torch for HFanalyses comes with an alumina injector. Hence simply interchange between
