Agilent Polaris NH2 HPLC columns are designed for separation of polar analytes in either normal phase or HILIC modes. The combination of ultra-pure silica and silanol shielding provides superior peak shape and retention with highly polar samples. Polaris NH2 provides superior stability and resolution for sugar and carbohydrate analysis. The columns feature 3 µm or 5 µm fully porous particles for use with HPLC methods.
