Description

Analysis Note HILIC mode on Ascentis Express OH5 provided rapid separation of neurotransmitters in highly MS-compatible mobile phases. The highest grade LC-MS solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
