In-Spec Spectrophotometric Standards

  1. 1. HOW IT WORKS: UV/Vis Spectrophotometer StandardsProblem: Having to verify GFS Chemicals also offersthat an instrument is other standards that can beperforming properly and is utilized to validate otherin calibration is becoming aspects of an instrument’sincreasingly common for performance.
