NIST Traceable Spectroscopic Standards

The highly regulated enviroment in which many laboratories now work demands that analytical measurements are made in a strictly controlled environment.
Starna Certified Reference Materials are the most conveniant tools for validating spectrophotometric measurements in the ultra violet and visible regions and satisfy the most stringent requirements of all international control bodies.
Starna CRM's are fully traceable to NIST primary standards and are manufactured under ISO Guide 34 conditions,accepted world wide as the highest standard Commercially available.
The certification process satisfies ISO 17025
Starna Scientific is the only supplier of UV/Visible CRM's to be approved as a reference material Supplier by UKAS, the United Kingdom Accreditation Service, (Ref. 4001) and to hold both ISO 17025 and guide 34 Accreditations.
All Starna CRM's carry a lifetime guarantee, provided they are used and stored correctly and recalibrated at intervals of not more than 2 years

Buy on-line, White Bear offers a wide variety of NIST traceable spectrometer standards.  Ultraviolet and visible spectrophotometers are fundamentally both accurate and precise but it is vital to check instrument performance on a regular basis to ensure that it is operating within satisfactory parameters. The reference materials provided by Starna are based on materials which have been used by national reference laboratories such as National Institute of Standards and Technology (NIST).  When used in periodic testing of your instrument’s performance you build a quality control database of the operating characteristics of your specific instrument. This database can then be used for the following purposes:

Why do you need to use reference materials?

* Demonstration of satisfactory instrument performance to any inspecting agencies.

* Detection of instrument malfunction.

* Provide data to a service technician allowing detection of instrument faults and assistance in repair.

Each spectrophotometer has specific operating characteristics based on the geometry and basic design of the optical system. These reference materials become your guide to the efficient operation of your instrument.

NIST (National Institute for Standards and Technology in Washington DC, USA) traceability is available on most of our reference materials. This traceability is established by the calibration of our Cary 5000 reference spectrophotometer using standards produced by NIST both before and after testing the Starna reference materials. We supply documentation with the Starna references detailing the analysis procedure, NIST traceability, the analyzed values of the reference and the confidence limits. The certification supplied with the Starna reference materials is suitable for use with inspecting agencies when used in the context of a standard operating procedure for quality control that is established in your laboratory. Our certification laboratory is inspected and accredited by UKAS under ISO/IEC 17025 and ISO Guide 34. This assures that the certifications of our reference materials are of the highest standards and are truly traceable.

260/280 Ratio Validation Reference

When running DNA or RNA purity analysis on your spectrophotometer it is important to assure that your instrument is working correctly. Our DNA/RNA validation standard is a permanently sealed quartz cell which contains a stable solution which mimics the 260/280nm ratio of DNA and RNA. The reference is supplied with a certificate which lists the expected 260/280nm ratio of the cell and the confidence limit of the ratio. The validation analysis is performed by our ISO 17025 accredited laboratory and is traceable to NIST.
