Purity is one of the most critical factors in chemical research. Even slight contamination can compromise data integrity, lead to invalid results, or pose unnecessary risk. At El Jardín Químico, every compound is thoroughly tested and validated with Certificate of Analysis (COA) and Safety Data Sheets (SDS). This blog details the methods used to verify purity—like gas chromatography and mass spectrometry—and explains why researchers should never compromise on quality. Learn how El Jardín Químico guarantees analytical-grade compounds and why our commitment to quality is trusted by labs worldwide.
