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.

Optimize Technologies EXP Trap Cartridge, 1mm x 5mm, 3.0µm EXP, C8, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
