The accuracy of GC-MS analysis services should be verified through documented method validation studies demonstrating precision, accuracy, linearity, and detection limits appropriate for your application. Request validation reports before committing to a service provider.
https://resolvemass.ca/gcms-method-development-service/
Metrics to Evaluate:
| Quality Metric | Industry Standard | What to Ask For |
|---|---|---|
| Precision (RSD) | <15% for most applications | Intra-day and inter-day precision data |
| Accuracy (Recovery) | 80-120% for trace analysis | Recovery studies in relevant matrices |
| Detection Limits | Matrix and analyte dependent | LOD and LOQ documentation |
| Linearity (R²) | >0.995 minimum | Calibration curve data |
Questions to Ask Potential Labs:
- What is your laboratory’s measurement uncertainty for target analytes?
- How frequently do you participate in proficiency testing programs?
- Can you provide examples of method validation reports?
- What are your typical recovery rates for compounds similar to mine?
- How do you handle out-of-specification results?
2. Turnaround Time: Balancing Speed with Quality
Most reputable GC-MS analysis services offer standard turnaround times of 5-10 business days, with rush services available in 24-72 hours for urgent projects. However, the fastest turnaround means nothing if accuracy is compromised.
Turnaround Time Benchmarks:
