Product Overview
The document provides a detailed overview of various analyzers used for elemental analysis in different materials. The analyzers are categorized based on the elements they analyze, such as Carbon (C), Hydrogen (H), Sulfur (S), Oxygen (O), and Nitrogen (N). Key products include the CS-580A series, CW-800 series, SurfaceC-800, ONH-2000, and H-500 analyzers.

CS-580A & CHS-580A Analyzers
These analyzers are designed for determining carbon and sulfur (CS-580A) and carbon, hydrogen, and sulfur (CHS-580A). They feature a vertical resistance furnace with a ceramic tube and offer options like an autoloader for sample handling. The measuring range for carbon is 0.0001% to 6% and for sulfur 0.0001% to 12%, with analysis times ranging from 45 to 60 seconds.

CW-800 Series
The CW-800 series is used for fractional analysis of carbon and water in both organic and inorganic materials. It features a resistance furnace with a quartz tube, capable of heating up to 1,000°C. The series allows for temperature and carrier gas modifications during analysis, with a measuring range for CO2 from 0.01% to 70% and H2O from 0.01% to 20%.

SurfaceC-800 Analyzer
This analyzer focuses on surface carbon content, which affects properties like rust formation and paint suitability. It uses a broad furnace with a quartz tube and measures carbon content from 0.1 to 1,000 µg/cm².

ONH-2000 Analyzer
The ONH-2000 is used for analyzing oxygen, nitrogen, and hydrogen in metals and ceramics. It employs inert gas fusion in an impulse furnace with temperatures up to 3,000°C. The analyzer uses thermal conductivity and infrared cells for gas detection.

H-500 Analyzer
Designed for hydrogen analysis in metals, the H-500 uses a resistance furnace with a quartz tube, operating at temperatures up to 1,000°C. It measures hydrogen content from 0.000001% to 0.1%.

TGA Analyzers
Thermogravimetric analyzers (TGA) measure mass loss under controlled conditions. They are used for analyzing parameters like moisture, ash, and volatiles in samples such as soils, fuels, and plastics. The TGA Thermostep and Thermochain models offer automated sample handling and high throughput.

Applications in Cement and Steel Industries
In the cement industry, ELTRA analyzers are used to determine carbonate and water content, crucial for quality control. In steel production, analyzers measure elements like carbon, sulfur, nitrogen, oxygen, and hydrogen at various production stages to ensure quality and compliance with specifications.

Dear readers, customers and business partners, In this special issue of the VERDER SCIENTIFIC customer magazine “the sample” we present to you ELTRA’s elemental analyzers and give you an overview of the methods and application areas. The concentrations of elements such as carbon and sulfur in metals and fuels are important parameters in many industry sectors which influence not only the product properties (carbon content in steel) but also the process control (flue gas desulfurization). In the field of high performance materials elements such as oxygen and hydrogen need to be measured in the...

Variety of applications ELTRA analyzers are used in production, quality control, and research and development. There is a very wide array of sample matrices that can be analyzed for their C, H, N, S, O concentrations and thermogravi metric parameters with ELTRA analyzers. In order to control the heating value in fuels such as coal, coke, waste, wood, or oil, analysis of the carbon content is necessary. In addition, efficient management of the desulfurization plant requires the control of the sulfur content. Both parameters (and optionally the hydrogen content) can be determined reliably with...

Ceramic materials As a result of its thermal characteristics, silicon carbide forms the basis of many mixtures in refractory linings in industrial furnaces. The proportion of SiC can be reliably and accurately determined in the CS-800 indirectly via the carbon content. The content of C, H, N, S and O influences properties such as ductility, corrosion tendency, or brittleness of almost any metal (e.g. steel, iron, copper, titanium, nickel). An effective ONH analysis is possible by means of an electrode furnace (ELTRA ONH series); for CS analysis with an induction furnace, the ELTRA CS-800 is used....
