Certified Reference Standards by EMPA and BAM
Certified reference standards or material constitute an essential tool in achieving
comparability and traceability of measurements.
In cooperation with two national institutes, the Swiss Federal Laboratories for
Materials Testing and Research (EMPA, Switzerland) and the Federal Institute for
Materials Research and Testing (BAM, Germany), Fluka offers three sets of
calibration standards:
• Standard titrimetric substances which can be used as primary or secondary
reference standards
• Cationic standard solutions for spectroscopic measurements
• Anionic standard solutions for ion chromatography.
The solutions contain 1000 ppm of the stated ion and are specially packaged in HD-
PE bottles sealed in airtight multilayer compound bags.
Each package is accompanied by a certificate including an analytical report. The
expiration date, certified property value and the confidence limit are also stated on the
product label.
