If you do not see something that you want, please just ask!
Mac-Mod Avantor Prevail Silica, 110 Å, 5 µm, 3.0 x 7.5 mm 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.

Waters HPLC Guard Cartridge, SunFire C8, 100Å, 10 μm, 10 x 10 mm
Optimize Technologies OPTI-GUARD 1mm Guard Column, Anion Exchange (SAX), (Black Label), 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
Waters Corporation Sentry Guard Cartridge, Amide, 3.5 μm, 4.6 x 20 mm
These Sentry Guard Cartridges are designed to retain extremely polar compounds, such as carbohydrates and sugars. They feature a chemically stable, trifunctionally bonded amide phase, stable from pH 2 to 11, for separating polar analytes across a wide range of polarity and pKa.
- Retains extremely polar compounds (e.g., carbohydrates, sugars).
- Chemically stable, trifunctionally bonded amide phase.
- Stable across a wide pH range (2 to 11).
- Separates polar analytes with varied polarity and pKa.
- Protects analytical columns by trapping particulates and strongly retained compounds.
- Ideal for HILIC applications, including sugars, glycols, and polar compounds.
- Compatible with common HILIC solvents (e.g., acetonitrile, water with buffers).
Waters Corporation Prep Guard Cartridge, 5 μm, 19 mm × 10 mm
This silica-based, reversed-phase C18 guard cartridge protects analytical columns and maintains optimal performance. It offers balanced retention for polar and hydrophobic molecules, making it ideal for separations of various compound types.
- Constructed from the same packing material as the analytical column for compatibility.
- Inserted between the injector and analytical column to prevent impurities and suspended solids.
- Designed for direct attachment to the column, minimizing excess volumes and reducing leaks.
- Manufactured in a cGMP, ISO 9001 certified plant using ultra-pure chemicals.
- Each batch of packing material undergoes chromatographic evaluation with acidic, basic, and neutral analytes.
