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 Microbial Count
What does CFU stand for, and what does it actually count?
- CFU stands for Colony-Forming Unit — a single viable microorganism (or small cluster) capable of growing into a visible colony on a nutrient medium. Counting CFUs rather than total cells specifically measures living, culturable organisms, which is what matters for contamination risk.
What is the difference between TAMC and TYMC?
- TAMC (Total Aerobic Microbial Count) quantifies viable bacteria, while TYMC (Total Combined Yeasts and Moulds Count) quantifies viable fungi — both are typically reported together as the standard baseline microbial quality indicators for raw materials and finished products.
How is microbial count testing actually performed?
- Common methods include plate count (spreading or pouring a diluted sample onto agar and counting resulting colonies after incubation) and membrane filtration (filtering a liquid sample through a membrane that retains microorganisms, then culturing the membrane), with the choice depending on the sample's expected microbial load and any antimicrobial properties that might otherwise inhibit growth on a direct plate.
Does microbial count testing also identify which specific microorganisms are present?
- A standard microbial count typically reports only total viable counts (TAMC/TYMC), not species identity; when specific organisms need to be identified — such as testing for the absence of specified pathogens like E. coli, Salmonella or Pseudomonas aeruginosa — separate specified-organism absence/presence testing is performed alongside the count.
What microbial count limits apply to cosmetic products?
- Limits vary by product category — leave-on products intended for use near the eyes or on children typically have stricter limits than general leave-on products, and rinse-off products often have more permissive limits, reflecting differing contamination risk and exposure; the applicable limit is determined by the product's category and intended use.
