The elementary analyzer vario EL works according to the principle of catalytic tube combustion in an oxygenated CO2 atmosphere and high temperatures. The combustion gases are freed from foreign gases (for instance volatile halogen). The desired measuring components are separated from each other with the help of specific adsorption columns and determined in succession with a thermal conductivity detector (TCD). Helium (He) serves as flushing and carrier gas.
Test components: The elementary analyzer vario EL is a fully automatic instrument for a speedy and quantitative determination of CHNOS. the instrument can - in different operation modes - determine the following elements simultaneously from one sample weigh-in: CHNS, CNS, CHN, CN, N, and S.
Depending on the purchased equipment . The suitability of the vario EL analyzer for the element analysis depends on the controllable combustibility of the samples or sample quantities.
Before processing methods: With precision of 0.0001 g scales has grinding samples of 0.3 ~ 0.5 g (0.5 g), and get in 50 ml centrifuge tube, separation of samples and supernatant after acid treatment, drying after grinding sample weighing, into the tin boat, wrap
Precision (theoretical): CHNS≤0.1% O2≤0.2%
