HPLC Guard Columns and Cartridges
Optimize Technologies OPTI-GUARD™ 1mm Guard Column, Method Development Kit, 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. This product allows you to pick 5 different cartridge packings for test and trial purposes.

Waters Corporation Column, ACQUITY Premier BEH HILIC, 1.7 μm, 2.1 mm × 150 mm
These BEH HILIC Columns, with unbonded BEH (Bridged Ethyl Hybrid) particles, are designed to retain and separate very polar compounds. They offer efficient, reproducible separations across a wide pH range. The BEH particle's chemical stability ensures long column lifetimes, making them more rugged than unbonded silica HILIC phases. Columns utilize MaxPeak High Performance Surface hardware technology to reduce unwanted analyte/surface interactions, preventing poor peak shape and signal loss. The VanGuard Fit column design protects from contaminants and increases column lifetime.
