We also handle products related to "specific aromatic amines and dye standards" for environmental analysis!

Specific amines (24 types) that have been pointed out as carcinogenic! Our company offers a wide range of mixed standard solutions, standards, and other reagents necessary for testing!

Regarding azo dyes that form specific amines (24 types) which are pointed out to have carcinogenic properties, measures are being taken to encourage restraint in their use in textile products and other areas from the perspective of preventing health damage. Our company offers a wide range of mixed standard solutions and standards used for the analysis of these specific amines, as well as the reagents necessary for this testing. In JIS L1940 (Textile Products - Quantitative Method for Specific Aromatic Amines Derived from Azo Dyes), benzidine-d8 is designated as the internal standard solution for amines eluted in the latter part of the analysis. On the other hand, "benzidine and its salts" fall under harmful substances prohibited from manufacturing under the Industrial Safety and Health Act, and manufacturing, importing, or using them in excess of 1% (weight%) is prohibited. We have begun handling products from LGC Standards Ltd. (Dr. Ehrenstorfer) as "standard solutions not exceeding 1% (weight%)".
