non-ionic emulsifiers
Application
Antifoam A has been used in a study to determine ultra trace arsenic species in water samples by hydride generation atomic absorption spectrometry after cloud point extraction. Antifoam A has also been used in a study to demonstrate a simple method to increase the amount of protein in a culture and to provide insight into how antifoams interact with microbial cell factories.
