Metformin hilic
WebHigh polar compounds, such as metformin (an oral antidiabetic drug in biguanide class) are not retained by reversed-phase chromatography. Instead, HILIC mode is suitable for the analysis of polar compounds. A polymer-based amino column, Asahipak NH2P-40 2D, was used in the LC/MS method. WebHILIC is considered a good alternative to ion-pair chromatography and the use of bonded phases with polar groups in the bonded phase. These applications typically require …
