REX
One Platform for NMR Relaxometry
REX is a vendor-independent software environment for the processing, analysis, visualization and interpretation of NMR relaxation data — from fixed-field measurements to Fast Field Cycling and NMRD analysis.
Developed by Extra Byte · Commercialized worldwide by SCIMERTECH

From Measurement to Scientific Interpretation
REX integrates key tools required to process, compare and interpret complex NMR relaxation datasets within one dedicated environment.
Relaxation Analysis
Analyze T₁ and T₂ relaxation curves and common recovery and decay experiments.
Relaxation Distributions
Explore discrete and continuous distributions using inverse Laplace transform workflows.
Fast Field Cycling
Analyze field-dependent relaxation data from Fast Field Cycling NMR systems.
NMRD Profiles
Visualize, compare and interpret nuclear magnetic relaxation dispersion profiles.
Variable Temperature
Investigate changes in relaxation behavior across temperature-dependent measurements.
Multivariate Analysis
Explore relationships and patterns in complex datasets using PCA and related tools.
A Common Environment for Relaxation Data
Import
Bring supported instrument data into one environment.
Process
Prepare FIDs, relaxation curves and measurement series.
Analyze
Apply fitting, ILT, NMRD, VT and multivariate tools.
Interpret
Compare datasets, visualize trends and extract scientific insight.
