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 Bromatological Analysis
What does bromatological (proximate) analysis actually measure?
- Bromatological analysis determines a food or feed product's basic nutritional composition — typically moisture, protein, total fat, ash (mineral residue), crude fiber, and carbohydrates (often calculated by difference from the other components) — providing the core data needed for nutritional labeling and formulation quality control.
How is protein content typically determined in bromatological analysis?
- Protein is commonly determined indirectly by measuring total nitrogen content (via the Kjeldahl or Dumas combustion method) and multiplying by a conversion factor specific to the food matrix (commonly 6.25 for general foods), based on nitrogen's typical proportion within protein molecules.
How is total carbohydrate content usually calculated?
- Carbohydrate content is most commonly calculated "by difference" — subtracting the measured percentages of moisture, protein, fat, ash and fiber from 100% — rather than measured directly, since it represents the remaining, largely unmeasured fraction of the sample.
Why is ash content measured, and what does it represent?
- Ash content represents the total inorganic mineral residue remaining after a sample is completely combusted at high temperature, burning away all organic material — it serves as an indicator of the total mineral content of a food or feed product.
What is bromatological analysis used for beyond nutritional labeling?
- Beyond generating label declarations, bromatological analysis supports raw material quality control (verifying incoming ingredients meet composition specifications), formulation consistency checks between production batches, and regulatory compliance for food, feed and nutraceutical products.
