What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

CONFIGURATIONS
The ELEMENTRAC OH-p 2 is available as a single-element analyzer for oxygen or hydrogen only, or in a multi-element configuration for measuring OH. Whereas oxygen is determined as CO2 in up to two infrared cells, nitrogen and hydrogen are detected in their elemental form in a thermal conductivity cell.

INTEGRATED STANDARD SOLUTIONS
The chemicals and filters required for the operation of the ELEMENTRAC OH-p 2 elemental analyzer are arranged conveniently on the front panel and can be concealed behind a removable door during routine operation. This arrangement significantly reduces the time required for maintenance and increases user-friendliness. In addition, innovative details considerably improve the reproducibility of measurements.
Innovative sample port & pulsed chamber flushing
The new sample port of the OH-p 2 elemental analyzer ensures comfortable operation and reproducible measured values. Differently shaped samples like solid pieces, granules or powder in capsules can be applied up to a weight of 2000 mg, and are quickly freed from the surrounding atmosphere with the help of pulsed carrier gas flushing in the sample port. Then they drop vertically into the preheated graphite crucible for analysis.
• Robust against dust development
• No closing of capsules required
• Direct application of up to 2000 mg granulate
• Low in maintenance and wear
Closed gas management
The ELEMENTRAC ONH elemental analyzer series uses a closed gas system in overpressure. This ensures that always 100% of the released sample gas is fed to the detectors which guarantees low detection limits and good reproducibility.

Options
In addition to the integrated solutions of the ELEMENTRAC OH-p 2 elemental analyzer, further options are available to increase efficiency and extend the application range.
AUTOCLEANER
By melting the sample in a graphite crucible at temperatures of up to 3000 °C deposits are generated at the upper electrode and in the furnace chamber which may affect the reproducibility of ONH measurements in a negative way.
The new optional Autocleaner reliably removes these deposits, enabling precise elemental analysis even for high throughputs. Additionally, an efficient gas calibration and cleaning furnace for thorough carrier gas pre-cleaning are available for the elemental analyzer.

Software
The comprehensive Windows-based ELEMENTS software is an essential part of all ELEMENTRAC generation elemental analyzers.
A central window (analysis and results) is the starting point from which all functionalities required for the daily routine are easily accessible. From here it is possible to group and export analyzed samples, or register and analyze new ones. The user may call up various subordinate functionalities like application settings, calibration, diagnosis, or status.

TYPICAL SAMPLE MATERIALS

FUNCTIONAL PRINCIPLE
The measuring principle of the ELEMENTRAC OH-p 2 elemental analyzer allows for a wide measuring range. To analyze the sample, it is weighed and placed on the sample port. Flushing with carrier gas prevents atmospheric gas (oxygen) from getting into the furnace.
The graphite crucible is outgassed in the impulse furnace of the analyzer to reduce possible contaminations (e.g. residual hydrogen). After a stabilization phase the sample is dropped into the crucible and melts. Carbon monoxide is produced by the reaction of carbon in the graphite crucible and oxygen of the material. Hydrogen is released in its elemental form. The carrier gas (nitrogen) and sample gasses pass through a filter before entering the Schuetze reagent which converts the CO to CO2, whereas hydrogen remains in its elemental form.
The CO2 is measured by the infrared cells and removed chemically. Afterwards the hydrogen content is determined in the thermal conductivity cell.

Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
