Each lot is released against the specifications listed above, and identity is confirmed by the method stated in the product record. A Certificate of Analysis covering appearance, assay and identity is issued with every shipment. We also work to custom specifications. If your process requires testing beyond the standard release panel, such as HPLC purity, residual solvent by GC, or a tighter purity limit, tell us what you need and we will quote it. Additional testing may carry additional cost and lead time.
