TraceSELECT™ Honeywell brand reagents


Ultra pure reagents for voltammetry

traceselect-imgVoltammetry is mainly used for inorganic analysis of anions and cations, but it can also be used for the determination of various organic compounds. The most important fields of application of inorganic determinations are in metallurgy, environmental analysis, food analysis, toxicology and clinical analysis. This technique is also a preferential method for the determination of some metallic species, such as Fe (II) / Fe (III) or Cr (III) / Cr (VI).

Solvents for analysis of trace metal specifications
TraceSELECT ™ solvents for LC-ICP-MS applications

Honeywell has developed high purity TraceSELECT ™ solvents for LC-ICP-MS analysis.
This is followed by UV spectroscopy, IC and ICP-MS testing to ensure high chemical purity and high UV transmittance. The blank values for metal traces in these solvents are in the ppb range or lower.

International trends show the speciation of metals as an area of high research interest. In the future, speciation of biological samples will undoubtedly result in the needing to identify which organic molecules attract which metals into specific types of samples. ICP-MS is a superior detection technique for trace elements in general, but above all for elements of interest, such as arsenic, selenium, cadmium, iodine and others in chromatographic eluents.

Sample preparation for trace analysis
TraceSELECT ™ Ultra e TraceSELECT™
Ultra pure acids, bases and salts for fusion and wet digestion in environmental, water and food analysis.

Sample preparation for trace analysis requires reagents of the highest purity.
The TraceSELECT™ Ultra products for ultrasonic analysis at ppb and also ppt levels are produced by sub-boiling distillation.
Sub-boiling is recognized as the best way to obtain high purity acids. The technique is based on the evaporation of the liquid by infrared heating on the surface.
To maintain their purity, TraceSELECT™ Ultra products are supplied in PTFE PFA (Floropolymer) bottles. Water and ortho-phosphoric acid are supplied in pre-leached HDPE bottles.
The acids, bases and salts of the TraceSELECT™ series have been developed for sample preparation and analysis in the ppb trace range (μg / kg).
