Uni-chem Chemical Reagents Certificate Of Analysis [patched] Official

While layout designs can vary slightly over time, a standard Uni-Chem chemical reagents Certificate of Analysis contains several core data fields. Understanding these fields ensures correct data logging and application. 1. Header and Administrative Data

This is the heart of the document. It is usually a two-column (sometimes three-column) table: , Specification , and Result .

Industrial manufacturing, large-scale cleanups, non-critical solutions. 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.

This is the core data table of the COA. It lists the parameters tested, the acceptable limits (specifications), and the actual values recorded during testing for that specific lot. Test Parameter Specification Limit Actual Lot Result Analytical Method Used ≥is greater than or equal to Gas Chromatography (GC) Appearance Clear, colorless liquid Passes Test Visual Inspection Residue after Evaporation ≤is less than or equal to Gravimetric Water ( H2Ocap H sub 2 cap O ) Content ≤is less than or equal to Karl Fischer Titration Heavy Metals (as Pb) ≤is less than or equal to 5. Authorization and Sign-off While layout designs can vary slightly over time,

: Often expressed as a percentage (e.g., 99.9%), indicating the concentration of the active reagent.

If an assay fails, checking the specific batch metrics on the CoA helps determine if the reagent is the source of the error. Key Components of a Uni-Chem CoA Header and Administrative Data This is the heart

Download the generated PDF document. It is best practice to archive a digital copy alongside your laboratory inventory logs for auditing purposes.

: Even 0.1% impurity can compromise data; the COA documents trace metal levels or moisture content to prevent experimental failure.
