儀器介紹ELEMENTAR公司始終是杜馬法快速定氮分析儀器的領(lǐng)導(dǎo)者和前驅(qū)者，從最初的經(jīng)典法裝置，直至現(xiàn)在的全自動儀器，產(chǎn)品不斷更新發(fā)展，每一種新研制的儀器都代表著這個時代的最高水平。The total concentration of halogens is in addition to a precise elemental analysis of CHNS or O particularly required for environmental samples but also for chemicals, fossile fuels, oil products and other industrial semi- and processed products. Elementar now offers the option for its elemental analyzers vario EL III and vario MACRO to also determine the sum of halogens (Cl, Br, I) by means of a special combustion and detection unit. The working range from 0.1 ?g to 50 ?g Cl allows the determination from trace levels up to high concentrations. The sample handling as well as the automatic determination of 79 samples by an integrated autosampler is simple ? as known from our elemental analyzers. The samples may be liquid or solid. The sample weight covers the range between 1 mg up to approx. 100 mg. The change from CHNS to halogen operation is easily possible.
