multi EA® 4000 – C, S and Cl solids analysis as easy and reliable as never before.
The multi EA® 4000 introduces a new generation of elemental analyzers for determining C, S and Cl in solid samples. Simple and straightforward determinations – TS, TC, TX, TOC, TIC, EC and AOC parameters in inorganic and organic solids: soil samples, sediments, construction materials, fuels, ashes, polymers, wastes, catalysts, minerals, and fertilizers.
The multi EA® 4000 is versatile, reliable and easy to operate, yet offers real macro elemental analysis. Sample weights up to 3 g can be analyzed with ease using the multi EA® 4000 – no laborious sample homogenization is necessary.
The HTC (High Temperature Ceramic) technology is extremely robust and needs no catalyst; it’s easy to run precise analyses, even with aggressive and corrosive samples at high temperatures!
The special wide-range NDIR Detector allows the simultaneous detection of carbon and sulfur over a broad, dynamic measuring range, all the way from ppm up to percent. Made from highly resistant materials, with a specialized optical configuration and efficient gas cleaning, this system requires very little maintenance and has long-term stability, even for the most challenging applications like direct TOC measurement. Elemental carbon or decomposable organic carbon determinations are also easy with the multi EA® 4000. A broad-range coulometer with a patented combination electrode is available for chlorine analyses across a wide range.
A large-capacity is optionally achieved thanks to a fully automated solid sampler which transfers the sample boats to the combustion furnace to get automated C, S and Cl analyses with amazingly high sample throughput. The sampler is also optimized for automated TOC (Total Organic Carbon) determination.
The multi EA® 4000 gives you fully automated determination of TOC and TIC (Total Inorganic Carbon) samples, with autosampler control in a single analysis process.
Additional features, such as the Self Check System (SCS), intuitive software navigation and an integrated “cookbook“, give you the best reliability, efficiency, flexibility, precision, and safety.
Advantages at a glance:
- Highly convenient operation
- Unique application diversity
- Intuitive software navigation
- Preset standard methods
- Minimal maintenance requirement
- Low operating costs
Determination of landfill-relevant organic carbon (OC) according to DIN EN 15936 and VGB pyrolysis method in waste from high-temperature processes
In this application note, Analytik Jena shows that the multi EA 4000 is well-suited to analyze the samples derived from high-temperature processes for different carbon species.
Determination of Total Chlorine in Derived or Secondary Fuels Using High-Temperature Combustion and Coulometric Titration
Waste materials are becoming more and more important as valuable feed materials for energy production, as fuels and recycled feed materials for the chemical industry. To ensure a trouble-free processing and high quality of the final products, the exact elemental composition has to be determined. This is also crucial for avoiding the emission of undesired hazardous compounds, such as chlorine. In this application note, discover a method for determination of chlorine using high-temperature combustion followed by coulometric titration.
Comparison of TOC Determination Methods in Soil Samples
This application note compares two methods for TOC determination in soil samples. Depending on the soil type and its TOC/TIC ratio, two different TOC determination strategies are available. The direct method is preferred in case of low TOC compared to the TIC present. It requires an extensive pretreatment of the sample to completely remove the interfering TIC (wet chemical acid digestion and drying of the treated samples). This method is also difficult to automate and negatively affects the hardware of the analyzer, in terms of consumables and maintenance.
From Farm to Fork: Solutions for Your Food Safety Requirements
Food safety strategy covers the safety of food for human consumption, but also animal and plant health. Analytik Jena shows how food is traceable as it moves from the farm to the fork.
This application note has been updated from the previous version published on April 4, 2017.
Calibration Strategies for Liquefied Pressurized Gases (LPG) with the Multi EA® 5000
This application notes describes two methods of calibration for the determination of sulfur in a sample of LPG. LPGs of known concentrations can be used as standards for calibration, or a common liquid standard can be used. However, whatever method is used, it is important to preserve the parameters of the gas measurement method so they are identical to the parameters of the liquid calibration.
Determination of Nitrogen Content in Heavy Petroleum Fractions
Heavy petroleum is very difficult to extract and analyze due to its high viscosity and high nitrogen content, and requires specialized strategies for quality control. The high nitrogen content in particular can slow down the refining process through poisoning of catalysts. This application note explains a modified combustion process to help with processing these 'difficult' matrices.
TOC and TIC Analysis in Soil Samples
This application note describes the elemental analysis of soil samples using the carbon/sulfur analyzer type multi EA. The carbon/sulfur analyzer type multi EA in combination with a separate TIC solids module allows TOC determination by both the direct method and the indirect method in compliance to the standard method EN 13137.
Biogenic Fuels and Renewable Energies – A Challenge for Elemental Analysis?
This application note describes a precise inspection of used raw materials, intermediate stages and end products from biogenic materials for the production of fuels and combustibles. The elemental analysers of the multiEA® series provide sensitive detection with automatically optimised, safe and complete combustion as implemented with flame sensor technology.
Determination of Chlorine in Waste Wood
Waste wood is becoming ever more important as a source of energy. A precondition for its use is that the content of harmful substances in the material used does not exceed the statutory limit values. In this application note, an analyzer of the Analytik Jena multi EA® Series was used with a multi matrix sampler to determine chlorine content in samples of waste wood.
