One sample or a complete batch
Bruker spectra, ramp grouping by gradient and diffusion time, ppm-based signal selection and independent gravimetric preparation per sample.
Explicit calibration
Probe, sequence, gradient shape and acquired TE temperature. Experimental calibration or absolute gradients when their magnitude is known. Internal references such as TTMS or solvent require identity and condition review by the researcher.
Inversion and components
Native C# TRAIn, MATLAB connection and an inversion-method API. Method-specific advanced parameters, distribution inspection and Gaussian approximations for component review. The selected component carries through to results and reports.
Nerea, contextual assistance
Local assistant, scientific rules and documentation in English and Spanish. Region and reference suggestions are review hypotheses, not automatic chemical identifications.
Reviewable results
Diffusion, hydrodynamic radius, apparent molecular weight, dispersity and width measures, with parameter and selection provenance. English and Spanish DOCX reports.
Availability
A 64-bit Windows WPF application under development and scientific validation. The current desktop branch is 0.23.2. MATLAB mode requires its environment; API methods require a configured service. Local Nerea models use additional resources.
No new installer or licence is released here. Distribution will be enabled when the team specifies the package and delivery conditions.
Interpretation limits
Diffusion-derived molecular weight depends on calibration and model assumptions. Linear-polymer calibrations do not validate absolute masses of branched, star or brush architectures. A good fit does not prove absence of convection. Gaussian separation does not identify chemical species.
