Waters Corp Atlantis VanGuard Cartridge, HILIC, Silica, 100Å, 3 μm
Atlantis HILIC VanGuard Cartridges extend the lifetime and performance of analytical columns by removing particulate contamination from the mobile phase. They are optimized to protect analytical columns containing 3 μm sorbent particles and are used with high organic mobile phases (>80% acetonitrile) to retain polar analytes, offering orthogonal selectivity compared to reversed-phase methods.
- Extends analytical column lifetime and performance.
- Removes particulate contamination from the mobile phase stream.
- Optimized for 3.9 mm and 4.6 mm I.D. analytical columns with 3 μm sorbent particles.
- Retains polar analytes using high organic mobile phases (>80% acetonitrile).
- Provides orthogonal analyte selectivity.
- Produced in compliance with cGMP and ISO 9001 standards.
- Ensures optimal efficiency, selectivity, sensitivity, and speed.

Waters Corp Waters Sentry Guard Cartridge, C8, 100Å, 5 μm, 2.1 mm X 10 mm
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
- C8 chemistry for general purpose method development at low pH.
- Less hydrophobic and less retentive C8 ligand compared to C18, suitable for specific assays.
- Spherical silica particle substrate.
- Particle size of 5 μm and pore size of 100 Å.
- Designed for HPLC systems.
- Maximum pressure rating of 6000 psi (415 bar).
- Available in a 2-pack.

Sepax Technologies Inc Sepax HPLC Column Proteomix WAX, NP10, Guard cartridge with holder, 4 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.
