Our Quality Control Practices
Our quality mission is to deliver the highest quality reference materials for life science research. Every batch is quarantined, sampled, and independently verified by accredited third-party laboratories.
Our Quality Mission
As a leader in the market, we are proud to drive innovation through a commitment to client goals, scientific rigor, sustainable operations, and public advocacy. We strive for continuous improvement by maintaining three foundational values:
Quality First
Every reference compound undergoes stringent quantitative purity assays and qualitative structural identity verification before release.
People Matter
We prioritize researcher success by delivering reliable, consistent products supported by responsive U.S. customer care.
Pursuit of Excellence
Continuous evolution of testing procedures, state-of-the-art analytical equipment, and transparent documentation for every lot.
Our Step-by-Step Quality Control Process
From raw material receiving to public COA publication, every step is strictly documented and audited.
Quarantine Isolation
When new raw material arrives, it is placed in a designated quarantine area separated from approved inventory. Only certified sampling technicians can access quarantined material.
Container-Level Sampling
To ensure total batch consistency, samples are taken from every single container in a shipment. A composite sample is blended and dispatched to an independent 3rd-party lab.
3rd-Party Lab Analysis
Each material undergoes quantitative purity testing, structural identity confirmation, heavy metal screening, and microbial pathogen culture panels.
Transparent Batch Tracking
Every batch is assigned a unique LOT # printed on the physical label. Corresponding Certificates of Analysis (COAs) are published publicly in our COA Library.
Third-Party Testing & Instrumentation
We utilize accredited independent laboratories equipped with high-precision analytical instruments.
HPLC Analysis
High Performance Liquid Chromatography (HPLC) passes pressurized liquid samples through adsorbent columns. Separation based on component retention times and light absorption peak area yields exact quantitative purity metrics (>98% target).
NMR Spectroscopy
Nuclear Magnetic Resonance (NMR) spectroscopy observes local magnetic fields around atomic nuclei using radio wave excitation. NMR provides definitive confirmation of monomolecular organic structure and functional group placement.
ICP-MS Heavy Metals
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) ionizes samples to detect trace metals down to parts per quadrillion (ppq). All batches are screened specifically for toxic heavy metals: Arsenic (As), Cadmium (Cd), Mercury (Hg), and Lead (Pb).
Microbiology Panel
Comprehensive microbial pathogen culture panels ensure products are below strict limits. Testing includes Total Aerobic Plate Count, Yeast & Mold Count, and screenings for E. coli, S. aureus, and Salmonella.
GC-MS Testing
Gas Chromatography–Mass Spectrometry (GC-MS) combines gas separation with mass spectral fingerprinting—the “gold standard” for detecting residual solvents, pesticides, and complex organic contaminants.
TLC Chromatography
Thin-Layer Chromatography (TLC) separates non-volatile liquid mixtures and complex botanical extracts across silica adsorbent sheets to monitor reaction progress and purity benchmarks.
