Analytical Reference Standards
Analytical Standards & Chromatographic Reference Materials
High-purity reference materials and spectroscopic calibration standards for academic and industrial research laboratories.
High-Performance Liquid Chromatography (HPLC) Standards
Our analytical reference materials undergo rigorous multi-step characterization including high-field nuclear magnetic resonance (NMR), mass spectrometry (MS), and reverse-phase high-performance liquid chromatography (RP-HPLC) to establish certified lot purity exceeding 99.0%.
| Parameter | Analytical Method | Acceptance Criteria | Batch Verification |
|---|---|---|---|
| Purity (RP-HPLC) | C18 Column · 214nm detection | ≥ 99.0% | Conforms |
| Identity (MS) | ESI-TOF Mass Spectrometry | Exact Molecular Weight ± 0.5 Da | Conforms |
| Residual Solvents | Headspace GC-MS | USP <467> Guidelines | < 0.1% w/w |
| Counter-ion Content | Ion-Exchange Chromatography | Trifluoroacetate / Acetate | Quantified per lot |
All reference products are strictly intended for scientific laboratory research and in-vitro analytical testing.
Quality Assurance & Storage Guidelines
Reference materials must be kept under controlled desiccated conditions at -20°C. Upon reconstitution in analytical grade sterile solvents, stock solutions should be aliquoted to avoid freeze-thaw cycles.
