How we test
We measure residual solvents by headspace gas chromatography (GC-HS) on an Agilent system. The standard list follows the common ICH Q3C solvents, and we can change it to match your process.
Results are given for each solvent, with units and conditions.
What we measure
| Method | Static headspace GC (GC-HS) |
|---|---|
| Solvent list | Common ICH Q3C solvents, or your own list |
| Units | ppm, for each solvent |
| Turnaround | 4–7 business days |
What is on the certificate
- Each solvent with the result and units
- Method conditions
- Test date and Certificate Number
What to send
- Solid or liquid in a tightly sealed container
- The solvents used in making it, if known
- Roughly how much you can send
Please wait for our packing instructions before you ship. They confirm amounts, container, temperature and where to send the samples.
