- With the classical method, even samples without hydrazine show a slight yellow coloration. With our modified method, hydrazine-free samples remain colorless. Therefore, a slight yellow coloration detected with our method corresponds to the actual presence of traces of hydrazine.
- The optical comparator contained in the package enables a color comparison between two test tubes containing the same amount of water, which is an advantage in terms of accuracy.
- HYDROCHECK kits enable many precise analyses to be carried out at a very low cost per analysis. If precision is not particularly important and the analyses to be carried out are few in number, it may be worthwhile using DROPS kits, which cost considerably less per package (to be purchased through dealers).
