EMIA-Step

Carbon/Sulfur Analyzer

In addition to the “EMIA-Expert/Pro” series of high-frequency induction furnace type, the “EMIA-Step” of tubular electric resistance heating furnace type has been newly added to our Carbon/Sulfur Analyzers lineup. It realizes highly accurate and sensitive analysis, and its variable heating temperature function enables the quantitative analysis by separating it by temperature and condition as well as whole quantity analysis.

Segment: Scientific

Division: Carbon/Sulfur & Oxygen/Nitrogen/Hydrogen Analyzers

Enables temperature control starting at a low temperature range

EMIA-Step provides good temperature stability from low to high temperatures. This broadens the application range to samples containing substances that are easily decomposed and burned at low temperatures.

<Temperature rise control from 300 °C to 900 °C>
You can easily see the decomposition combustion of organic matter and inorganic matter respectively.
New dust-filter provides easy maintenance capability

EMIA-Step adopted the proven dust-filter mechanism in the high frequency induction heating models. The filter unit collects the dust generated by combustion at high temperature. This prevents the dust from adhering to piping after the combustion furnace, and reduces adsorption of CO2 and SO2 gases by dust. This mechanism makes highly accurate and sensitive analyses possible.

Quantitative analysis of carbon contained in bone substitute material

Can we accurately and quickly measure the amount of carbon contained in the material?

Can free carbon in SiC be rapidly and conveniently quantified?

Sulfer is added in the natural rubber to produce plastic materials. However, it is important to measure the sulfer contained in the rubber to define the chemical and mechanical properties of the final product.

This application note describes the method and conditions to use with the EMIA 820V C/S analyzer to measure cement.

Ferrosilicon is added as a deoxidant and as an alloying element to steel, that require a special low carbon content. The Low Carbon in Ferrosilicon decreases the electrical conductivity and magnetostriction of electrical steels.

Copper in reddish metal, it is malleable, ductile and an extremely good conductor of both heat and electricity. Copper metal is widely used for electrical wiring, water piping, and corrosion resistant parts, either pure or in alloy such as brass and bronze. Carbon and Sulfur are considered as impurities, so it is important to measure and check the Copper purity.

Titanium oxide are used primarily in the production of paints and plastics and are also used in paper, priniting inks, cosmetics, textiles and food stuffs.

Carbon Analysis: Organic and Inorganic Carbon in Soils

The aim of this application note is to explain the determination of organic and inorganic carbon in soils and how to prepare samples to eliminate inorganic carbon (carbonates) in these soils.
