Uni-chem Chemical Reagents Certificate Of Analysis _top_ Jun 2026

A for Uni-Chem chemical reagents is a critical quality assurance document that verifies a specific batch of chemicals meets defined purity and performance standards. Think of it as a "report card" for that specific bottle or drum, ensuring your laboratory results are accurate and reproducible. Key Components of a Uni-Chem CoA

| Component | Description | |-----------|-------------| | | e.g., “Uni-Chem Sodium Chloride, AR Grade, Cat# UC-1001” | | Batch/Lot Number | Unique identifier for traceability | | Manufacturing Date | Date of production | | Retest/Expiry Date | Recommended date for re-analysis | | Appearance | Physical description (white crystalline powder, clear liquid, etc.) | | Assay (Purity) | Percentage purity (e.g., ≥99.5% by titrimetry) | | Identity Tests | Confirmation via IR, Na⁺/Cl⁻ spot tests, or retention time (HPLC) | | Impurities | Limits for chlorides, sulfates, heavy metals (as Pb), iron, etc. | | Loss on Drying | Moisture content (e.g., ≤0.5% w/w) | | Residue on Ignition | Non-volatile inorganic residue | | Solubility | Compliance with specification | | Test Methods | References to standard procedures (AOAC, USP, in-house) | | Signature/Approval | Quality control officer’s name and date | uni-chem chemical reagents certificate of analysis

In the high-stakes world of analytical chemistry, pharmaceutical research, and industrial quality control, a chemical is only as reliable as its documentation. When a scientist opens a bottle of solvent or a vial of standard, they are not just looking for a formula—they are betting the validity of their experiment on the purity of that substance.
