Comprehensive Lab Capabilities
Nutraceutical Testing Panels & Analytical Solutions
Our analytical suite covers every phase of dietary supplement verification, protecting your product reputation and meeting international customs criteria.
Microbial & Pathogen Screening
Full microbiological testing including Total Aerobic Microbial Count (TAMC), Total Yeast & Mold (TYMC), E. coli, Salmonella, Staphylococcus aureus, and Pseudomonas aeruginosa.
Heavy Metal & Trace Elemental Testing
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) detection for lead, cadmium, mercury, and arsenic down to parts-per-billion (ppb) safety limits.
Raw Material Identity Verification
Fourier-Transform Infrared Spectroscopy (FTIR) fingerprinting, HPTLC, and macroscopic microscopy ensure raw material authenticity and eliminate adulteration risk.
ICH Stability & Shelf-Life Validation
Accelerated (40°C / 75% RH) and real-time environmental chamber storage programs to substantiate expiration dates and packaging barrier efficiency.
Contaminant & Residue Screening
Gas Chromatography-Mass Spectrometry (GC-MS) for multi-residue pesticide screens, residual solvent limits (USP <467>), and allergen cross-contamination verification.

Standard Operating Procedure
Our 4-Stage Quality Assurance Workflow
A transparent and validated sequence designed to ensure total product integrity from raw material intake to finished goods dispatch.
01
Material Quarantine & Sampling
All incoming raw ingredients are quarantined and sampled using ISO-compliant statistical protocols.
02
Analytical & Microbial Assay
In-house laboratories execute identity, potency, heavy metal, and microbiological testing panels.
03
In-Process Quality Checks
Weight variation, hardness, friability, disintegration, and fill volume monitored throughout production.
04
CoA Release & Sample Retention
Finished goods are reviewed against master specifications; CoAs issued and retention samples stored for full shelf life.
Quality FAQs
Frequently Asked Questions About Quality Testing
Technical guidance regarding laboratory protocols, testing turnaround times, and documentation standards.
Every CoA includes comprehensive lot details: product identity, physical description, active ingredient assay/potency results, complete microbiological panel, heavy metal levels (Pb, Cd, Hg, As), disintegration parameters, batch number, manufacturing date, expiry date, and pass/fail sign-off from our QA Manager.
In-process quality testing occurs in real time during production runs. Full finished-goods release testing (including 5-day microbial cultures and analytical assays) typically takes 5 to 10 business days. Expedited testing options are available for urgent client shipments.
Yes. In addition to our internal QC testing, we regularly coordinate sample submissions with ISO 17025 accredited third-party laboratories and certification organizations such as NSF International, Informed Choice, USP, and Organic certifying bodies to meet specialized retail or athletic brand requirements.
We offer both accelerated stability testing (40°C / 75% Relative Humidity for 6 months, simulating 24 months of shelf life) and real-time stability testing (25°C / 60% Relative Humidity). Samples are periodically pulled and assayed to ensure active potency and microbial safety hold throughout the target expiration date.
Yes. While analytical testing is included with all full-service contract manufacturing projects, we also provide standalone laboratory testing and stability study services for brands needing third-party batch verification or regulatory compliance audits.
