O que é MICROCT
Uma técnica de análise avançada
Non-destructive three-dimensional analysis of internal material structure.
What sets us apart
We don't hand over a spectrum. We hand over the interpretation.
Any lab can return peaks and numbers. Our report reads the data. Three differences define what we deliver — illustrated below with a real, anonymized case.
Multiple techniques, one integrated report
We don't hand back five loose reports. We cross-reference every technique's results into a single reading — each signal checked against the others — to reach an answer, not a pile of data.
- Contamination investigation — identifying and tracing the source of a foreign species.
- Performance degradation — explaining why a batch behaves outside expectations.
- New supplier validation — proving equivalence before switching.
3 LDPE batches · 4 techniques converge, NMR reveals the difference
In semicrystalline polymer systems, thermomechanical processing variables influence chain conformational dynamics¹. Solid-state NMR resolves chemical environments at the nanometer scale², sensitive to changes not detectable by XRD or FTIR³.
Technical justification anchored in the literature
Every technique choice and every inference in the report is backed by peer-reviewed literature — with citations in the text. The conclusion isn't loose opinion: it's a traceable argument, defensible in an audit and in front of the client.
- Numbered citations linking claim to source
- Official standards and methods referenced per analyte
- Auditable reasoning end to end
Conclusion and expert opinion
The report closes with a clear position, signed by the Principal Investigator: what the data shows, what can't yet be claimed, and the next step. It includes an honest caveat on the limits of inference — what separates a technical opinion from a guess.
- Explicit technical position, not just results
- Inference limits declared honestly
- Next-step recommendation signed by the P.I.
Four techniques confirmed equivalence; only the solid-state NMR revealed the subtle conformational change not distinguishable by conventional QC — a molecular signature consistent with the atypical filtration behavior.
Without the industrial line's parameters, no direct causal correlation can be established — a complementary step is recommended for elucidation.

FAQ
Frequently Asked Questions about Computed Microtomography (Micro-CT)
How does micro-CT create a 3D image without cutting the sample?
- Micro-CT rotates the sample (or the X-ray source/detector) to capture many 2D X-ray projection images from different angles, then reconstructs them computationally into a full three-dimensional volume — the same principle as a medical CT scan, but at micrometer-scale resolution.
What resolution can micro-CT achieve, and how does it compare to nano-CT?
- Micro-CT typically resolves features in the range of roughly 1 to 50 micrometers, sufficient for internal defects, porosity, and layer structure in most tablets, materials and devices. Nano-CT extends this to sub-micron resolution for finer internal features, at the cost of a smaller field of view and longer scan times.
Can micro-CT quantify porosity, not just visualize it?
- Yes — because micro-CT reconstructs a full 3D volume, image analysis software can segment and quantify pore or void volume, size distribution, and spatial connectivity throughout the sample, not just show a qualitative cross-section.
Is micro-CT destructive to the sample?
- No — micro-CT is non-destructive, since it images the sample's existing internal structure using X-rays without cutting, polishing, or otherwise altering it, so the same physical sample remains available for further testing afterward.
What kinds of internal defects or features can micro-CT detect?
- Micro-CT can visualize and quantify internal voids, cracks, delamination between layers, coating thickness and uniformity, and the 3D distribution of different-density components within a single sample — information a 2D cross-section or surface technique cannot provide.
