Ultraviolet, visible and NIR spectrophotometers are fundamentally accurate, however it is vital to check instrument performance on a regular basis to ensure operation is within acceptable parameters.
Certified references provided by Starna are based on materials, which have been used or produced by a National Metrology Institute (NMI), such as the National Institute of Standards and Technology (NIST) or fundamental metrological principles. When used in routine testing of instrument performance, a quality control database of the operating characteristics for a specific instrument can be built. This database can then be used for the following purposes:
- Demonstration of satisfactory instrument performance to any inspection or regulatory agency.
- Detection of instrument malfunction.
- Provide data to a service technician allowing detection ofinstrument faults and assistance in repair.
- Construction of Process Control Charts
