ELEMENTAL ANALYZERS

ELEMENTAL ANALYZERS The analyzers of ELTRA's new ELEMENTRAC series are a combination of high functionality, elegant design and innovative features. The user-friendly operation, robust construction and precision of the instruments are further indicators of the high product quality. The ELEMENTRAC ONH series is used to analyze oxygen, nitrogen and hydrogen concentrations in inorganic sample materials reliably, accurately and safely by inert gas fusion. ★ Optimized sensitivity thanks to closed gas system ★ Use of cost-efficient argon as carrier gas possible ★ Water-cooled sample port system ★...

Oxygen, Nitrogen, Hydrogen Analysis Oxygen, nitrogen and hydrogen strongly influence the properties of metals such as steel, titanium, copper. Brittleness, ductility and hardness are particularly influenced by the element concentration; hence a reliable and precise measurement of these elements is an important part of the quality control process. ELTRA supplies analyzers for the determination of the single elements O, N, H as well as for the combinations ON, OH and ONH. The ELEMENTRAC ONH series uses inert gas fusion. This method involves heating the sample in a graphite crucible to 3,000 ...

Quick results thanks to easy operation Operation of the ELEMENTRAC ONH analyzers is easy, safe and convenient. First the sample is weighed, then logged into the sample list and finally introduced to the sample port system. Refractory materials such as titanium or ceramics need to be placed inside a nickel capsule or basket first. The next step is to place a graphite crucible, which may contain more flux melting agent (e. g. tin), on the lower electrode. The analysis is started in the software upon which the impulse furnaces closes. The measurement results are available 2 to 3 minutes later....

Gas system The ELEMENTRAC ONH series uses a closed gas system in overpressure to ensure that 100 % of the released sample gas is lead to the detectors to guarantee low detection limits and good reproducibility. The efficient economy mode during analysis breaks helps to reduce carrier gas consumption and hence operating cost. Controlled catalyst with moisture filter A powerful, controlled catalyst heats the contained copper oxide to 750 °C thus ensuring the complete transformation of the CO formed in the graphite crucible to CO2. Before the CO2 analysis in the infrared cells starts, water is...

Technical Details ELEMENTRAC® ON-p | OH-p | ONH-p Powerful furnace technology and new sample port system: ° Impulse furnace provides temperatures in excess of 3,000  C The impulse furnace and the sample port system are essential components of the ELEMENTRAC ONH series. The sample port system ensures complete purging of the sample from atmospheric gasses as well as its safe and loss-free transport to the Impulse furnace graphite crucible. The sample is melted in the furnace and the contained gasses are fully and uniformly released. Powerful 8.5 kW furnace The generator of the ELEMENTRAC ONH...

Sensitive thermal conductivity cell with optional use of argon Whereas the oxygen content of a sample is measured with infrared cells, hydrogen and nitrogen are determined in their elemental form with the help of a robust thermal conductivity cell with a wide measuring range. This cell was optimized for integration into the ELEMENTRAC ONH analyzers and permits the use of cost-efficient argon as carrier gas. Thermal conductivity cell with high sensitivity foil The innovative ELEMENTRAC thermal conductivity cell is based on a micromechanical silicon chip which is coupled to a membrane and...

Resistance furnace Precise determination of H2 also in large samples For the determination of the total hydrogen content in inorganic sample materials by inert gas fusion both ELEMENTRAC OH-p n High-capacity thermal conductivity cell and ELEMENTRAC ONH-p are suitable. Another option is ELTRA’s n Easy calibration with standards or gas n Precise measurement even of low concentrations n For samples of up to 10 g and 0.8 x 6 cm H-500 analyzer which measures hydrogen by hot extraction in The H-500 is equipped with a resistance furnace with quartz tube which can be heated to 1,000  °C. By using...

Operation H-500 Operation of the H-500 is easy and safe. After weighing the sample, for example in a quartz boat, the weight is transferred to the connected PC. It is also possible to enter the weight manually in the H-500 software. The sample is placed into the cold zone of the horizontally positioned furnace (fig. 1). After the analysis has started the furnace is rotated upwards (fig. 2) for the sample to fall into the hot zone. By adding nitrogen as carrier gas hydrogen diffuses out and is carried to a thermal conductivity cell with up to two different sensitivities. The typical analysis...
