Environment/Agriculture/Food Applications
Analysis of the O, N, H content of a wide range of materials is a challenging task. Especially when coupled with exploration of materials property through elemental analysis.
Several analysers have been specially optimised for use in the enviromental and agricultural fields. ELTRA® has over 30 years of experience in the construction of elemental analysers for the determination of the carbon, sulfur, nitrogen, oxygen and hydrogen content in a variety of organic materials.
Thermogravimetric Analyser TGA Thermostep
- Elements: ash content, moisture , volatiles
- Samples: inorganic, organic, synthetic
- Analysis of up to 19 samples
- Fully automatic analysis
Thermogravimetry is a standard method to analyse organic, inorganic and synthetic materials. Thermogravimetric analysis in general means the measurement of the weight loss during a user-defined temperature or heating process.
ELTRA’s TGA Thermostep is a thermogravimetric analyser which determines various parameters such as moisture, volatiles and ash at user-defined temperatures and atmospheres in a single analysis. The thermogravimetrics analyser TGA Thermostep simultaneously analyses up to 19 samples with sample weights up to 5 g and can be operated at temperatures up to 1000 °C.
A special feature of the TGA Thermostep is the management of crucible covers. The thermogravimetric analyser can place and remove the covers of the crucibles during analysis. This feature allows for example the precise determination of volatile content in coal and coke.
ELEMENTRAC CS‑r Carbon / Sulfur Analyser
- Elements: carbon, sulfur
- Samples: organic
- Autoloader: no
For the safe, precise and reliable elemental analysis of carbon (C) and sulfur (S) in predominantly organic matrices such as soils, waste, wood, oil, coal and coke, ELTRA offers the combustion analyser ELEMENTRAC CS-r with IR detection.
The CS-r with up to 4 infrared cells is designed for carbon and sulfur measurement over a very wide concentration range. It uses a horizontal resistance furnace with ceramic tube, which operates in a range from 600 °C to 1550 °C.
The CS-r elemental analyser meets or exceeds the requirements of all common ASTM, DIN, EN or ISO standards for elemental analysis.
CS‑580A Carbon / Sulfur Analyser CS‑580A
- Elements: carbon, sulfur
- Samples: organic
- Autoloader: yes
ELTRA‘s CS-580A is the ideal analyser for the simultaneous determination of carbon and sulfur in organic samples.
ELTRA’s 580A analysers (A = Autoloader) are equipped with an automatic sample loader, allowing for analysis of large numbers of samples without operator intervention. The sample loader is available in two versions to accommodate 36 or 130 crucibles. The CS-580A is based on the technology of the CS-580 analyser and features a vertical resistance furnace with ceramic tube.
ELEMENTRAC CHS‑r Carbon / Hydrogen / Sulfur Analyser
- Elements: carbon, hydrogen, sulfur
- Samples: organic
- Autoloader: no
For the safe, precise and reliable analysis of carbon (C), sulfur (S) and hydrogen (H) in predominantly organic matrices such as soils, waste, wood, oil, coal and coke, ELTRA offers the elemtal analysers ELEMENTRAC CHS-r with IR detection.
The CHS-r with up to 3 infrared cells is designed for carbon, sulfur and hydrogen measurement over a very wide concentration range. It uses a horizontal resistance furnace with ceramic tube, which operates in a range from 600 °C to 1550 °C.
The CHS-r combustion analyser meets or exceeds the requirements of all common ASTM, DIN, EN or ISO standards for elemental analysis.
