Inorganic Ventures now offers custom ICP and IC calibration standards in smaller, 30 mL volumes. They have up to a three-year shelf life in sealed transpiration control technology bag. The smaller volumes offer total cost savings, ship as non-hazardous, produce less lab waste, enable simplified inventory management and increase confidence by reducing the likelihood of contamination.
Now available for ICP and ICP-MS grade single element standards. As well as the potential for less waste, the smaller volume makes shipping quicker and cheaper.
Range of elemental impurities CRMs to meet the new method’s permissible daily exposure (PDE) levels. There is also an internal standard solution optimised for best ICP-MS results with pharmaceutical samples. Available in a cost effective and conveniently packaged kit.
Instrument Systems have introduced a new calibration standard series for the calibration of luminous flux and intensity of LEDs.

Sigma-Aldrich Corporation has signed an exclusive global distribution agreement with IROA Technologies, LLC to distribute IROA’s Mass Spectrometry Metabolite Library of Standards™ (MSMLS). MSMLS is a collection of small molecules that span a broad range of primary metabolism. These are high purity (>95%) compounds supplied in an economical, ready-to-use format. The library of standards is...
John Hammond updates us on “Reference materials: what’s new?”. The 2015 meeting of the ISO Committee on Reference Materials (ISO/REMCO) was held in June and significant developments in a number of standards that will ultimately affect all users of reference materials have taken place.
Hellma is the leading supplier for glass and quartz cuvettes, fiber optical probes and certified reference materials for UV/Vis/NIR/Raman/IR spectrophotometers and many other instruments using optical measurements. All products are made in Germany and ensure reliable measurements in optical analysis.
The Starna Group is the world\'s leading supplier of Certified Reference Materials for UV-Visible and NIR spectrophotometry, spectrophotometer cells, sampling accessories and optical components
C. Burgess and J.P. Hammond outline the work that has been undertaken to modernise the spectroscopic General Chapters in the United States Pharmacopeia (USP).
John Hammond and Chris Burgess are also in the middle of a multi-part contribution to the Quality Matters column. “…that’s what I thought you said?” looks at further misundertandings in terminologies surrounding Reference Materials, and sets the record straight.
Peter Jenks clarifies “What is a ‘Primary Standard’?”.
John Hammond reports on important developments at the ISO Committee on Reference Materials (ISO/REMCO) annual meeting.
Peter Jenks and John Hammond describe how the important ISO 17025 standard has developed, and point out that a review for the third edition of the standard will start soon. All those with an interest in quality standads—an increasing number of us—should make sure their voice is heard at their local standards body.
Peter Jenks and John Hammond continue their series on “CRMs and PT in an ISO 17025 accredited laboratory” with instructions on how you can prepare your own in-house certified reference materials.
Peter Jenks looks at some current trends in the supply of CRMs and proficiency testing and highlights difficulties labs may have been when no commercial CRM is available. This will be followed with a second part looking at the production of in-house reference materials.
Peter Jenks gains new respect for microbiologists and learns that the way they approach analytical quality control is different from chemists.
Chris Burgess and John Hammond respond to Peter Jenks' thoughts in the last issue's Quality Matters Column. Please join in the debate and add your comments at the end of the article.
The reasoning behind strict compliance to an ISO Standard is logical, but the consequences can be commercially questionable, if not unsound. Peter Jenks, and many other scientists, are starting to question the commercial viability of all this regulation. What is your opinion?
Peter Jenks is concerned at the lack of mutual help available on the Internet within the field of analytical chemistry. Other fields, outside science, have strong communities where enthusiasts give freely of their advice and time; why not in analytical chemistry? Please tell us your views by adding a comment to this column article.
The 33rd meeting of the Reference Material Committee of ISO, ISO/REMCO was held in Hangzhou (China) from 3 to 7 May 2010, and was hosted by the Standardisation Administration of China and the China Association of Standardisation. ISO/REMCO now has a membership of 70 members of the International Organisation for Standardisation (ISO) and liaison with 18 international organisations...

ISO 17025 has been with us now for 12 years and in some industry sectors it is getting hard to find a commercial laboratory offering chemical testing that is not accredited to ISO 17025 for some or all of its scope. In just 12 short years the importance of “...
