MetaChem stocks a
comprehensive line of single anion and multi-anion solutions,
in both 100ml or 500 ml sizes. These ion chromatography
standards are made with meticulous attention to detail,
beginning with the very purest raw materials available
(generally >99.999% pure) and 18 megohm deionized water.
The solutions are prepared gravimetrically; raw materials
are weighed with ±0.0001g accuracy, on balances which
are regularly calibrated using NIST-traceable weights.
Class A volumetrics are routinely calibrated according
to NIST recommended procedures. All bottles are triple
rinsed in deionized water to avoid contamination.
A wide battery of quality assurance tests evaluate each
standard before shipment. The final concentration of each
batch is verified against an NIST SRM (when available),
and each standard is accompanied by a certificate of analysis
that states the actual concentration, the traceability
to NIST and the expiration date.
MetaChem also provides single and multi-ion solution standards
to meet your specifications. Custom standards are produced
with the same attention to detail and provided with the
same documentation as our stock standards. Simply contact
MetaChem to discuss your particular needs. |
