For nearly 20 years, GFS Chemicals has been making NIST traceable, certified reference materials for spectrophotometric analysis and verification. The IN-SPEC line of standards includes standards not just for photometric accuracy but also for wavelength, stray light, and resolution for a variety of UV-VIS instrumentation.
IN-SPEC materials are:
- Non-toxic so there is no disposal fee
- NIST traceable meaning they meet regulatory requirements
- Customizable and can be tailored to meet your needs
- Live technical assistance for help with method development
