Application Notes

 
Determination of Total Cyanide in Municipal Wastewater and Drinking Water Using Ion-Exclusion Chromatography with Pulsed Amperometric Detection (ICE-PAD)
Application Note

Dionex - Part of Thermo Fisher Scientific

Cyanide is a well known acute toxin that prevents cellular respiration by irreversibly binding with the iron in cytochrome C oxidase. In addition, thiocyanate, which is metabolized from cyanide, interferes with iodine uptake by the thyroid gland, causing goiters and other long-term iodine deficiency diseases.

Quantitation Limit of Pharmaceuticals by UV Spectrophotometry
Application Note

Shimadzu

Quality control and securing product safety are important in the manufacture of pharmaceutical products, so it is essential that substances other than those specifically approved are not included with the specified ingredients. This means that contaminants from the environment must not become mixed in with the product ingredients and residual substances adhering to the manufacturing equipment must not contaminate the next product to be processed by that equipment.
