Waters, 186009955, AccQ•Tag Ultra C18, 1.7 µm, VanGuard Pre-Column, 2.1 x 5 mm, 3/Pk

The AccQ•Tag Ultra C18, 1.7 µm, VanGuard Pre-Column, 2.1 x 5 mm connects directly to the inlet of the AccQ•Tag Utra column which minimizes extra columns volumes and reduces leaking by eliminating additional connections. It protects the analytical column from matrix and sample contaminants, extending column lifetime. This guard column is compatible with: p/n: 186009953 AccQ•Tag Ultra C18, 1.7 µm, 2.1 x 50 mm Column p/n: 186003837 AccQ•Tag Ultra C18, 1.7 µm, 2.1 x 100 mm Column p/n: 186009954 AccQ•Tag Ultra C18, 1.7 µm, 2.1 x 150 mm Column
