Romil has become the first European commercial producer of
elemental certified reference materials (CRMs) to be accredited
to ISO 17025 as a calibration laboratory.
This award gives Romil
the authority to certify reference materials and to market Romil
PrimAg CRMs bearing the Ukas (United Kingdom Accreditation
"The demand for properly SI-traceable
certified reference materials has grown rapidly, as ISO 17025 is
adopted as a quality standard by both European and Global
analytical laboratories", says Robert Lenk, founder and
managing director of Romil.
He comments: "Until now there
has been no way for most laboratories to source affordable, fully
SI-traceable CRMs for analytical calibration.
makes it possible for us to certify our PrimAg range of CRMs so
that they meet all the requirements of labs working to ISO
The most important feature of PrimAg CRMs is that
they require no further analytical validation to demonstrate
traceability to the SI.
The need to use CRMs that are traceable
to an SI unit is written into ISO 17025.
For analytical chemists
this unit is the mole.
Before the introduction of PrimAg CRMs,
generally the only available solution element CRMs that provided
traceability to the mole were those produced by the US National
Institute of Standards and Technology, Nist.
Outside the USA,
supply tended to be unreliable and prices high.
Now, Romil PrimAg
CRMs ensure analysts have a ready supply of fully SI-traceable
CRMs for trace element calibration at a price that is no more
than the non-traceable analytical standards produced by the
general laboratory reagent companies.
"To certify PrimAg
CRMs we use an unbroken chain of comparisons to a sample of very
pure silver, effectively a 'practical mole'"
explains Dr Lenk.
"This concept of silver traceability has
been established within the central analytical laboratories of a
number of leading European chemical manufacturers for almost a
century; Romil is the first to recognise the benefits this
concept will bring to the wider laboratory market" he added.
He went on to say that Romil would be extending and developing
the concept to offer fully traceable analytical reagents for use
in many more critical applications.
