LC-MS additives are selective chemicals that are commonly added to the mobile phase in LC-MS. The objective is usually to improve the signal quality, but they can also be used to suppress unwanted signals or selectively enhance the signal of specific compounds in a mixture
- High quality and LC-MS application tested
- Improved ionisation and resolution
