Melamine & Contaminant Screening
Trace-level screening for melamine — the classic protein-inflating adulterant — by LC-MS/MS under NABL ISO/IEC 17025 accreditation.
About Melamine Screening
Economic adulteration evolves faster than the standards that chase it, and melamine — added to fake a higher protein reading — remains the textbook case after the infant-formula tragedy that put it on every regulator's radar. CVR Labs screens dairy and infant products, plant proteins and feed for melamine by LC-MS/MS at trace levels, the sensitivity needed to expose adulteration that ordinary protein assays cannot see.
Because a nitrogen-based protein test (Kjeldahl or Dumas) counts melamine's nitrogen as if it were protein, only a targeted mass-spectrometry method can tell genuine protein from a nitrogen-spiking fraud. For brands and importers, this is the screen that protects against engineered adulteration before it becomes a recall.

Why melamine screening matters
The single accredited parameter for this service is melamine; the searchable scope follows below.
Melamine fakes protein
Melamine is added to inflate apparent protein; only targeted LC-MS/MS detection exposes the fraud, which basic nitrogen-based protein assays cannot.
Adulteration is a moving target
Economic adulterants change with price pressure; trace-level mass-spectrometry catches nitrogen-spiking substitution that routine composition tests miss.
Infant and dairy lines are highest risk
Melamine's history is in dairy and infant nutrition, where the consequences and the regulatory scrutiny are greatest.

How melamine screening is tested
Reference method applied
Melamine is quantified at trace levels by LC-MS/MS under a validated in-house CVR SOP within the accredited scope, reported against the applicable FSSAI / Codex limit so compliance status is clear.
