HPLC Guard Columns and Cartridges
Waters Corp Spherisorb C8 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb C8 columns are general purpose, silica-based reversed-phase columns that contain an Octyl ligand. These USP L7 columns are used when you require a less retentive sorbent compared to the Spheriorb ODS columns.
Waters Corp Spherisorb C6 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb C6 columns are general purpose, silica-based reversed-phase columns that contain a linear-hexyl ligand. These USP L15 columns are used when you require a less retentive sorbent compared to the Spheriorb ODS columns.

Waters Corp Protein-Pak Diol (OH) Sentry Guard Cartridge, 125Å, 10 µm, 3.9 mm X 20 mm, 1K - 80K, 2/pk
10 µm diol-bonded gel filtration materials.
Waters Corp SunFire C18 Prep Guard Cartridge, 100Å, 10 µm, 19 mm X 10 mm, 1/pk
SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Waters Corp XBridge BEH C18 Prep Guard Cartridge, 130Å, 5 µm, 19 mm X 10 mm, 1/pk
As a workhorse for HPLC method development, XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1-12). The trifunctionally bonded C18 ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed.

Waters Corp SunFire C18 Sentry Guard Cartridge, 100Å, 5 µm, 4.6 mm X 20 mm, 2/pk
SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Waters Corp Spherisorb SCX Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb SCX columns contain an anionic silica-based sorbent. This strong cation- exchange sorbent is used to separate positively charged ionic species.
Waters Corp ACQUITY UPLC BEH C18 VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
As the premier column for method development, the 1.7 um ACQUITY UPLC BEH C18 sorbent provides you with the most universal column choice for UPLC separations. The trifunctionally bonded BEH particle gives you the widest usable pH range (pH 1-12), superior low pH stability, and ultra-low column bleed for high sensitivity MS applications. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
