What Does FASI Stand For?

FASI stands for Field Amplified Sample Injection

FASI, or Field Amplified Sample Injection, is an analytical technique used in capillary electrophoresis that enhances the sensitivity of detection by concentrating analytes from a sample before their introduction into the separation medium. This method utilizes a distinct sample injection process where an electric field is applied, allowing for the selective accumulation of target molecules, thereby improving resolution and overall analytical performance. FASI is particularly beneficial in situations where sample volumes are limited or where trace-level detection is required.
