ISO 34 Standards

With advancements in technology and the ever greater demands from regulatory bodies to identify new analytes and the lowering of detection limits, Greyhound recognises the importance of supplying Certified Reference Materials with validated and stated uncertainties. Scientists are under increasing pressure to produce accurate reports using the technologies currently available to them and to minimise random and systematic errors in their procedures.

European and other accrediting bodies including the United Kingdom Accreditation Service (UKAS), specify the use of ISO Guide 34 Certified Reference Materials under certain circumstances. In the absence of ISO Guide 34 Certified Standards, scientists assume the laborious, time consuming task of calculating and documenting the uncertainties associated with the calibration standards they use.

The ISO Guide 34 Certified Reference Materials offered by Greyhound have their major components of uncertainty identified and documented, including homogeneity, short and long term stabilities and the uncertainty due to analytical characterisation.

For the past 20 years High Purity Standards Inc. has manufactured NIST traceable, Inorganic Standards for instrument calibration which are today manufactured in accordance with ISO Guide 34:2009. In addition, the rapidly expanding range of Organic Reference Standards have been developed to answer the call from analysts seeking a reliable source of Organic Standards which are manufactured specifically to meet the requirements of ISO Guide 34:2009. This exclusive range is detailed in the new ISO Guide 34 Organic Standards catalogue from Greyhound Chromatography.

Meeting ISO standards

High-Purity Standards understands a comprehensive quality system is key to our customers’ confidence in the products that we manufacture. That’s why we developed our Total Quality System with the help and assessment of an independent agency to meet the requirements of three separate ISO standards: ISO 9001:2008, ISO/IEC 17025:2005 and ISO Guide 34:2009.

Comprehensive Product Testing

At High-Purity Standards, being called a Certified Reference Material requires extensive testing including:

Certified Value Assignment
Batch homogeneity testing — for each lot
Long-term and short-term stability testing

NIST Traceability

For inorganic standards, the scope of HPS ISO Guide 34 certificates has been limited only to those products that can be validated against the NIST Standard Reference Material 3100 series. This validation process meets the requirements established by NIST for maintaining direct NIST traceability. National Institute of Standards and Technology (NIST)

Where NIST Standard Reference Materials do not exist, HPS uses second sources provided by reputable CRM suppliers to provide an independent validation of products. Consequently, the certificate for these products will not include the ISO Guide 34 icon. HPS distinguishs between Certificates of Analysis by only placing icons on products that pass the most rigorous testing for traceability.

Reading the Certificates of Analysis

Each CofA provides detailed and specific information as to the extensive analysis behind the manufacturing of each product. HPS uses the best practices throughout this process, but should you encounter a discrepancy or concern we would welcome your phone call.
Introducing some highlights from the range,

FTPH-M17C for testing Total Petroleum Hydrocarbons

Underground storage tanks (UST) containing fuels and hazardous materials are prone to leaking and end up contaminating soil and groundwater. Our featured new product FTPH-M17C is a standard/retention-time-window-defining standard designed to test for total petroleum hydrocarbons from possible leakage. It consists of seventeen even chain alkanes from C8-C40 in n-hexane.

Other standards in development focus on EPA testing procedures and popular organic pollutant detection mixtures, such as– PAH-HM16C, containing sixteen Polynuclear Aromatic Hydrocarbons named by the EPA as priority pollutants. PCBs, Pesticides and volatile organics in a range specifically designed to support the environmental forensics chemist’s work. Custom organic standards are also available upon request.

We also offer a range of ISO 34 Inorganic Certified Reference Materials, you may find our Standards search a useful tool
