With the publication of ISO 17505:2025, laboratories worldwide now have a unified protocol for differentiating carbon species in soils, sludges, and solid wastes.
The new ISO standard aligns closely with EN/DIN 17505:2023, but gives international weight to a methodology long adopted in Europe. ISO 17505:2025 covers:
-
TOC400: Total Organic Carbon determined at 400 °C
-
ROC: Residual Oxidizable Carbon (e.g., ROC600/900)
-
TIC900: Total Inorganic Carbon determined after pyrolysis at 900 °C
The PRIMACS™ SNC-100 supports both Method A (oxidative ramping) and Method B (inert gas switching), delivering fast, compliant, and highly accurate data — all in a single automated run.
As global regulations demand more robust carbon reporting, ISO 17505:2025 provides the foundation — and the PRIMACS™ SNC-100 delivers the solution.
✅ ISO & EN/DIN compliant
✅ Broad matrix compatibility
✅ Automated operation with high sample throughput
