Uncertainty

The certified values) and uncertaintvlies) are determined in accordance with FURACHEM/CITAC Guide for
"Quantifying Uncertainty in Analytical Measurement3rd edition”with an 95%confidence level(k=2).Uncertainty is based on the Total Combined Uncertainty,including uncertainties of characterisation and stability testing.Stability values are based on real evidence opposed to simulation.

The producer certifies that this reference material meets the specification stated in this certificate until the expirv date provided it is stored unopened at the recommended temperature herein.Product warranties for this reference material are set out in the terms and conditions of purchase.

Intended Use

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.

Safety

Proper precautions should beobserved while handling.See Safety Data Sheet.

Traceability

The balances used for gravimetric measurements are calibrated with weights traceable to the national standards(DKD).The calibration of the balances is verified daily internally and annually by an external accredited calibration service.Chromatographic methods are traceable to the
International System of Units(SI).

Storage

The RM should be stored in the original sealed container at the indicated temperature.

Instructions for use

It is recommended to use 1 mg as the minimum sample size and if less material is usedto increase the
certified uncertainty by a factor of two for half sample and four for a quarter of sample.If storage after opening is necessary,the RM should be tightly closed and kept from light and moisture. If the RM was in a sealed ampoule, it should be transferred to a vial with minimum head spaceVisit the support section of our website lgcstandards.com for a series of Dr.Ehrenstorfer Tech Tip videos and frequently asked questions.
