标准品/帕拉金糖水合物

This certificate is designed in accordance with ISO 17034 and ISO Guide 31. This reference material (RM) was designed,produced ａnd verified in accordance with ISO/IEC 17025, ISO 17034 and a registered quality management system ISO 9001.

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.

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.

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

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.

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.

Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.

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.
