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 the NAD+/NADH Ratio
What does the NAD+/NADH ratio indicate about a cell's health?
- The NAD+/NADH ratio reflects a cell's redox state and metabolic activity — a higher ratio (more oxidized) is generally associated with active energy metabolism and healthy mitochondrial function, while a lower ratio (more reduced, NADH-dominant) can indicate metabolic stress, altered glycolytic-to-oxidative balance, or age-related metabolic decline.
How is the NAD+/NADH ratio actually measured?
- Common methods use an enzymatic cycling assay that generates a colorimetric or fluorescent signal proportional to NAD+ and NADH levels in a cell extract, allowing each to be quantified separately and their ratio calculated — distinct from assays that measure only overall metabolic activity without distinguishing the oxidized and reduced forms.
How is NAD+/NADH measurement different from a Seahorse XF metabolic analysis?
- NAD+/NADH quantification is typically an endpoint assay on a cell lysate, providing a snapshot of the redox cofactor balance at one moment, while Seahorse XF measures oxygen consumption and acidification in real time on live cells — the two are complementary, with NAD+/NADH offering a specific redox cofactor readout and Seahorse providing continuous functional respiration data.
Why is the NAD+/NADH ratio relevant to anti-aging and longevity research?
- NAD+ levels are known to decline with age and are linked to reduced mitochondrial function and cellular resilience, making the NAD+/NADH ratio a relevant biomarker for evaluating NAD+ precursor supplements, senolytic compounds, and other interventions targeting cellular metabolic aging.
Can the NAD+/NADH ratio be used to evaluate cosmetic actives?
- Yes — because the ratio reflects cellular energy status and redox balance, it is used to substantiate claims about an ingredient's effect on skin cell vitality, rejuvenation or metabolic support, typically alongside other cellular energy assays such as ATP quantification.
