- Label all aliquots with the compound name, concentration, date of reconstitution, and operator initials for complete traceability.
Quality Assurance & Analytical Verification
Apex Laboratory applies a dual-verification quality protocol to every batch before it enters inventory. Each lot undergoes High-Performance Liquid Chromatography (HPLC) to confirm chromatographic purity and Mass Spectrometry (MS) to verify molecular identity and molecular weight. This two-step analytical process ensures that the material you receive meets our ≥99% purity standard with confirmed molecular integrity. Certificates of Analysis documenting these results are available upon request for your internal quality records.
