| Select the testing and documentation that best meets your requirements: |
| Gravimetric |
| |
Components are guaranteed to weigh within ± 0.5% of the amounts you specify. A Certificate of Composition (COC) is included. The COC states the exact amount of raw materials used, the purity and lot number of each raw material. |
| Qualitative |
| |
The composition is verified by GC or LC. A COC is provided along with a chromatogram. |
| Quantitative |
| |
The standard is compared to a separately prepared reference batch of the same formulation, using the internal standard method (GC) or the external standard method (LC). A Certificate of Analysis (COA) is included. The COA includes a chromatogram, gravimetric measurements, raw material purities, and the concentration of each component and its uncertainty value. Complimentary data packets are available upon request. |
