NexChrom guides you through every step — intuitively, accurately, and traceably.
| ❶ Instrument & Sample Setup Register GC instruments, locations, and samples. Link CDS data files from Agilent, Thermo, Scion, or Shimadzu. | ❷ Method Configuration Define analytical methods with component roles: direct (calibrated), indirect (via RRF), or fixed (certified). |
| ❸ Calibration Build polynomial calibration models with four regression methods (OLS, WOLS, GLM, EIV/ISO 6143). Interactive calibration curves and residual plots with automatic model order determination. | ❹ Execute & Calculate Run calculations combining sample data, calibration model, and method. Results stored with full traceability. |
| ❺ Review & Approve Inspect calculation results, approve or reject runs. Historical models preserved for re-calculation. | ❻ Certificates Generate analysis certificates. Import external reference certificates from PDF (VSL, NPL, NMi) with OCR support. Track validity and cylinder numbers. |
