    Uncertainty
    The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95** confidence level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation, homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.
    Traceability
    The balances used for gravimetric measurements are calibrated with weights traceable to the national standards. The calibration of the balances is verified annually by an external accredited calibration service. This analysis method has been verified using an approach consistent with ISO 17034:2016 & ISO 17025:2017.
    Method of Identification
    HPLC
    Batch Information
    TGA: 1.5**

    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.
    Storage
    This reference material meets the specification stated in this certificate until the expiry date, provided it is stored unopened at the recommended temperature here in. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture.
    Hazards
    Read Material Safety Data Sheet (MSDS) and understand any potential hazard(s) prior to the use of this product. All chemicals should be considered potentially hazardous in nature and should only be handled by qualified personnel using established good laboratory practices.
    Homogeneity
    Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.
    Instructions for use
    It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample.Visit the support section of our website technology videos and frequently asked questions.
