Nova-Pak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 4 µm particle technology. Compared to a 5 µm column, Nova-Pak columns offer higher resolution, more efficient separations, and faster chromatography.
Perkin Elmer US LLC Brownlee Aquapore Octyl RP-8 NewGuard Cartridge - 15 mm x 3.2 mm I.D., Pkg. 3
Brownlee Aquapore Octyl RP-8 NewGuard cartridges are based on a spherical silica support suitable for the separation of large biopolymers. These cartridges prolong column life by 2 to 5 times while protecting columns from particulates and strongly bound sample components. Actual bed length of each 15 mm NewGuard is approximately 13 mm. These NewGuard Cartridges require a holder: To couple with a conventional column - NewGuard Holder (07150001) To couple with an MPLC cartridge - Union (07150018) Quantity: Package of 3 Interaction Mode: Reversed Phase USP Code: L7

Accessories for HPLC Columns
Optimize Technologies EXP Guard Column Cartridge, 1.5mm x 5mm, C8, 1.8µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
Optimize Technologies EXP2 Stem Trap Kit, 0.17µL, 3.0µm EXP, 3.0µm EXP, C4
A standard EXP™2 Stem Trap Kit includes (1) EXP™2 Stem Holder and (3) packed stems. Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP2 Stem Trap an unbeatable choice for ultra high-pressure trapping applications. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP2 Stem Trap seals to 8,700+ psi. Additionally, the product can be wrench tightened to 20,000+ psi (1,400+ bar). The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection. The replacement stems are low volume/ low-dispersion, intended for many repeat uses and is available with various bed volume and custom packing options. This product is recommended for nano flow applications.
Optimize Technologies EXPGuard Column Cartridge, 1mm x 5mm, Phenyl-Hexyl, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape.

Mac-Mod Avantor Prevail C18, 110 Å, 5 µm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
