Thermo Scientific Dionex IonPac NS1 and NS2 Columns
IonPac NS1 and NS2 HPLC Columns from Thermo Scientific
Thermo Scientific IonPac NS1 10 µm and NS1 5 µm columns are packed with a neutral, macroporous, high surface area, ethylvinylbenzene polymer crosslinked with 55% divinylbenzene. This resin makes the NS1 resistant to solvents, acids, and bases, and permits the use of eluent from pH 0 to 14. The IonPac NS1 column is the column of choice for routine ion pair chromatography.
IonPac NS2 is a silica-based column for mobile-phase ion chromatography (MPIC) applications using eluents containing trifluoroacetic acid (TFA), heptafluorobutyric acid (HFBA), or tetrabutylammonium borate (TBAB). It provides high performance analysis for hydrophobic amines and hydrophobic acids using suppressed conductivity detection.
Thermo Scientific Dionex IonPac NS1 and NS2 polymeric reversed-phase columns are ideal for the separation of hydrophobic, ionizable compounds.
