PerkinElmer Pure Atomic Spectroscopy
PerkinElmer offers a wide selection of atomic spectroscopy
calibration standards. Each solution is supplied with a
comprehensive Certificate of Analysis that documents the
quality and reliability.
Quality
PerkinElmer Pure standards are prepared gravimetrically from
high-purity metals and salts, using high-purity reagents.
■
ASTM Type I, filtered water minimizes cations, anions and colloids;
resistivity is maintained in the 18-megohm range
■
Acids used are the highest purity
■
Semi-micro analytical balances and Class A volumetric glassware are
used and the bottles are subjected to a stringent leaching/cleaning
process
■
Following preparation, standards are analyzed for the major element
as well as trace impurities. The results of the analysis are provided on
the Certificate of Analysis
Reliability
Single-element standards are measured by four methods:
1. ICP/ICP-MS analysis of the high pure starting materials for trace
impurities (semi-quantitative).
2. Gravimetric, “wet” assay of the major analyte.
3. ICP check of the major analyte.
4. ICP/ICP-MS check of the trace impurities in the final solution.
Whatever your application, you can depend
on
PerkinElmer Pure Standards
to yield reliable, accurate results
Features
■
ISO 9001 accredited by Underwriters Laboratories including
comprehensive continuous improvement, product recall,
corrective action request and other quality maintenance
and improvement programs

■
Bottles are low-density polyethylene from industry standard Nalge
Corporation and are pre-leached and pre-treated for increased
product stability and purity
■
High-purity acids and ASTM Type I water used in all manufacturing
■
Traceability directly to NIST standard reference materials, not
independent sources or secondary NIST SRMs
■
Wet assays on all single-element products via standard, accepted
wet methods and traceable directly to NIST SRM to +/-0.5% of true
value and reported on the Certificate of Analysis
■
All starting materials tested and confirmed for the absence of
interfering anions, e.g. chloride
■
Twelve months guaranteed stability +/-0.5% for all major analytes
for all products
■
Compliance to ISO 17025 quality system requirements.
