SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Waters Corp XSelect HSS C18 Prep Guard Cartridge, 100Å, 5 µm, 10 mm X 10 mm, 1/pk
The HSS C18 is a general-purpose C18 bonded phase column that provides superior peak shape for bases, increased retention (vs. XBridge C18 columns), and exceptional column lifetimes at low pH. The selectivity and retention observed with HSS C18 columns will resemble that of most modern, fully endcapped, high-coverage silica-based C18 columns.
Optimize Technologies OPTI-GUARD™ Biocompatible 1mm Guard Column, C18, 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.
