Environmental regulation "RoHS2.0 related reagents" adds regulated substances to the special grade standards!

Environmental regulation "RoHS2.0 related reagents" adds regulated substances to the special grade standards!

In response to the revised RoHS directive, we have released a RoHS2 compliant standard that adds four phthalate ester substances! The guaranteed values are below 1/10 to 1/100 of the regulatory values.

The RoHS Directive is a directive from the European Union (EU) regarding the restriction of the use of certain hazardous substances in electrical and electronic equipment. Until now, we have been releasing standards compliant with RoHS, but with the revised RoHS Directive (RoHS 2.0) that came into effect on July 22, 2019, the number of restricted substances has increased from 6 to 10. As a result of this directive, we have released RoHS 2 compliant standards that include 4 additional phthalate esters. [List of regulated substances under the revised RoHS Directive] Cadmium Lead Hexavalent chromium Mercury Polybrominated diphenyl ethers Polybrominated diphenyl Di-2-ethylhexyl phthalate Dibutyl phthalate Butyl benzyl phthalate Diisobutyl phthalate Similar to the previous RoHS compliant standards, we have added the 10 regulated substances of RoHS 2.0 as standard items in the special grade standards. Additionally, the guaranteed values are set to be less than 1/10 to 1/100 of the regulatory values. In addition to mixed standard solutions and standard materials for environmental analysis, we also handle JCSS compliant standard solutions and certified standard materials. Please choose according to your analysis needs. For more details, please download the catalog or feel free to contact us.

Moisture measurement reagent "Karl Fischer reagent"

Moisture measurement reagent "Karl Fischer reagent"

Co-developed with HIRANUMA Corporation: "Aqualight" Series

The "Aqualight" series is a reagent developed for Karl Fischer measurement, starting with HIRANUMA's moisture measurement devices "Volumetric Method: AQV/MOIVO Series" and "Coulometric Method: AQ/MOICO Series." In the 18th revision of the Japanese Pharmacopoeia, the moisture measurement method (Karl Fischer method) has been significantly revised. Based on the premise that appropriate moisture measurement can be confirmed in conformity tests, it has become possible to flexibly use commercially available moisture measurement reagents, taking into account the solubility of samples and potential interference with the Karl Fischer reaction. For details on each product, please refer to the catalog.

Handling of polystyrene-based particle suspensions for water quality testing "related products for turbidity measurement."

Handling of polystyrene-based particle suspensions for water quality testing "related products for turbidity measurement."

In addition to the conventional kaolin standard solution, we also offer a polystyrene-based particle suspension that is adopted in drinking water quality standards. You can choose according to your purpose.

"Related products for turbidity measurement" are reagents used in testing methods targeting the water quality standard item "turbidity." Traditionally, kaolin standard solutions were used for turbidity measurement; however, due to the increasing precision of measuring devices and the need to address pathogenic microorganisms such as Cryptosporidium, measurements in low turbidity ranges, such as 0.1 NTU, are now required. The water quality standards for drinking water allow for measurements in low turbidity ranges, and polystyrene-based particle suspensions have been adopted as turbidity standard solutions with less variability between batches compared to kaolin. Measurement methods include visual turbidity methods, transmitted light measurement methods, scattered (reflected) light measurement methods, integrating sphere photometric methods, and particle counting methods, which are used for device calibration and as turbidity standard series. 【Product Lineup】 ≫ Polystyrene Turbidity standard solution II for water quality testing (100 NTU) ≫ Formazin Formazin standard solution (400 NTU) ≫ Kaolin Turbidity standard solution for turbidity testing (100 NTU) Turbidity standard solution for turbidity testing (1000 NTU) In addition to these, we offer a variety of standard products for water quality testing. ◇ Pesticide standard solutions ◇ Metal analysis standard solutions …etc. For more details, please download the catalog, refer to our published page, or feel free to contact us.
