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.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.

ADVANTAGES FOR HIGH-THROUGHPUT LABORATORIES
ROBUST
Designed for high-throughput analysis and continuous operation, guaranteeing durability and reliability.
EFFICIENT
Fully automated and process-optimized total nitrogen and carbon determination using the Dumas method.
WIDE RANGE OF SAMPLES
The ELEMENTRAC CN-r delivers precise Dumas protein results for any sample matrix, whether solid or liquid. With the advanced features of the ELEMENTRAC CN-r, you get precise results for a wide range of samples.
HIGH PERFORMANCE
Analyze your samples in less than 3 minutes! Our intelligent processing allows simultaneous combustion of the current sample and analysis of the previous sample (so-called interleave analysis). Get results over 70 times faster than with the Kjeldahl method and benefit from unparalleled speed in your analysis workflow.
INTELLIGENT INTEGRATION
The built-in PC with touchscreen and network-capable data and process management ensures seamless operation and high comfort.
LOW OPERATING COSTS
Economical use of resources, intelligent gas-saving functions, and smart use of consumables lead to low costs per sample compared to other devices.
PRIORITIZED SAMPLES
High-priority samples take precedence and are measured immediately without having to be re-sorted in the autoloader.
EFFORTLESS MAINTENANCE
All consumables can be replaced in less than 20 minutes, keeping your system always ready for use. An optimized workflow with quick and effortless maintenance ensures smooth operation with minimal downtime.

SOFTWARE
The comprehensive ELEMENTS software is an essential component of all elemental analyzers of the ELEMENTRAC generation.
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 to register and analyze new samples. The user can access various subordinate functionalities such as application settings, calibration, diagnostics, audit trail, user group management or status and is FDA 21 CFR Part 11 compliant.
In addition, thanks to the network integrity and web browser architecture, you can access the device from any computer in the company network and have all data available at any time.

The Dumas method for protein and nitrogen determination is internationally recognized and validated by leading organizations such as AOAC, AACC, ISO, DIN, ASBC, AOCS, and OIV.
Typical Dumas protein applications include the analysis of:
• Foods to determine protein content, such as in grains, dairy products, and meat
• Animal feed to verify nutrient composition
Typical Dumas nitrogen applications include the analysis of:
• Soil samples to evaluate nitrogen availability for plants
• Fertilizers to determine nitrogen content and thereby fertilizer quality

Unedited feedback from customers who reorder ELEMENTRAC CN-r.
★★★★★
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.
