ICP (Inductively Coupled Plasma)

The development and spectacular growth experienced by modern instrumental techniques such as ICP-OES and ICP-MS, especially for environmental analysis, means that high performance reagents are required.

Ultra pure reagents for metallic traces analysis

PanReac AppliChem presents its ranges of ultra pure reagents for trace metal analysis at levels of ppb and ppt in order to satisfy the increasing demand of reagents for the traces analysis in the environmental, quality control and research laboratories. Two purity levels are provided to target a wide range of applications involving trace metal analysis by AAS, polarography, AAS-GF, ICP-OES and ICP-MS.
For trace metal analysis (ppb): This range consists of acetic, hydrochloric, nitric, sulfuric, hydrofluoric and perchloric acids. For all of them, a metal impurity content of less than 0,1 ppb (μg/L) for 60 different elements is guaranteed in most cases. The range comes in new 500mL, 1000mL and 2.5 L high density polyethylene (HDPE) bottles.
For trace metal analysis (ppt): These reagents are specially purified by multiple distillation until products have the lowest impurity levels, obtaining products that can be used as a baseline for the analysis of trace metals. In order to be able to reduce the impurity levels to the maximum , the process of manufacturing of reagents for trace metal analysis (ppt) has been optimised to the maximum. The greatest challenge has always been to minimize the impurities of some elements like Fe, Zn, Ni and Cu with a special analytical importance and limit the presence of elements such Ca, Na and Al which are ubiquitous in the environment as well as in the container materials. Thanks to this special care in the manufacturing, this range is able to offer reagents with concentrations below 100 ppt (ng/L) with the previous elements and most less than 10 ppt (ng/L). It represents the range of reagents with the lowest metal content intended to the metal traces analysis. Our reagents for trace metal analysis (ppt) are available in the following sizes in both Teflon PFA and FEP: 250 mL and 500 mL. Water and ammonia solution are available in specially washed HDPE bottles.

Standards

We offer ICP single element standards in concentrations of 1.000 and 10.000 g/L and ICP multi-elements standards containing up to 24 elements in concentrations of 1000 mg/L or 100 mg/L. Preparation is carried out using raw materials of the highest available purity: 99.999 % for metals as well as ultra-pure water and acids.
The concentration of each element is strictly controlled to an accuracy of ±0.2% of the true value, with NIST traceability. Traces of 69 elements are analysed by ICP and the result is specified on the certificate of analysis.
ICP standards are available in pre-washed 100-mL PE bottles, all of which are supplied with their corresponding detailed certificate of analysis. This certificate includes the composition of the standard, its date of manufacture, minimum expiry date, the actual value with respect to guaranteed value, traceability and the concentration of trace impurities.
