We offer a high range of single element standard solutions (1000mg/L) suitable for AAS or ICP respectively. The ICP standards are tested for up to 70 trace impurities whose concentrations are stated in the certificate.
AAS standards are supplied in 250 mL HDPE bottles except for Hg, which is bottled in 100 mL borosilicate white glass bottle.
The following AAS standards are supplied in 100 mL HDPE bottles: Pd, Au, Pt, Sc.
ICP standards are supplied in 100 mL HDPE bottles and sealed in an aluminum bag, including the certificate. For the AAS standards, the certificate can be downloaded from the web, using product number and lot number.

Certified Standards for Ion Chromatography (IC)

The portfolio of TraceCERT^® products includes 10 anion and 15 cation standard solutions for IC (concentrations: 1000 mg/L). The products are supplied in 100mL HDPE bottles. As a unique feature for these IC standards we list the most common trace impurities that are relevant for the ion chromatographic separation (13 elements for cation standards and 7 inorganic anions for anion standards). The certificates are available on the web using product and lot number.
