A COA is a formal document that provides validated analytical data for a specific production lot of a chemical reagent. Unlike a general product specification sheet, which lists what a product should be, the COA tells you exactly what that specific batch is after laboratory testing. Key Components of a Uni-Chem COA
Details on the methods used for analysis, such as HPLC, GC-MS, or titration. uni-chem chemical reagents certificate of analysis
He frantically checked the specification sheet on the wall. For ACS Grade Hydrochloric Acid, the limit for Lead was strict: . A COA is a formal document that provides
: For Uni-Chem entities that do not have an automated online database, such as the Belgrade-based Uni-Chem d.o.o. , you may need to request the document via their contact page or by calling their technical department at +381 11 3282 986. He frantically checked the specification sheet on the wall
: Even 0.1% impurity can compromise data; the COA documents trace metal levels or moisture content to prevent experimental failure.
Measurements of trace metals, water content, or non-volatile matter, usually expressed in parts per million (ppm) or percentages. 4. Certification and Dates Release Date: When the batch was tested and approved.
He looked at the keyboard.
