HPLC Guard Columns and Cartridges
Waters Corp Waters Guard Column, 200 Å, 2.5 μm, 4.6 x 30 mm
Waters Guard Column, 200 Å, 2.5 μm, 4.6 x 30 mm
Optimize Technologies OPTI-GUARD™ 1mm Guard Column, C4, 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 Corp Torus Diol (OH) VanGuard Pre-column, 130 , 1.7 m, 2.1 mm X 5 mm, 3/pk
Torus Diol (OH) VanGuard Pre-column, 130 , 1.7 m, 2.1 mm X 5 mm, 3/pk
Tosoh Bioscience LLC TSKgel UP-SW Aggregate DC Guard Column for 4.6 mm ID column, 3 um, 2 cm L
TSKgel UP-SW Aggregate DC Guard Column for 4.6 mm ID column can be directly connected to the TSKgel UP-SW Aggregate analytical column without tubing between the two columns. A male-type outlet endfitting on the guard column enables the direct connection to the screw-type endfitting of the analytical column.
Trajan Scientific HPLC Reverse Phase Protecol C18 1/EA
C18G x 5 m particle size x 120 pore size 250 mm length x 4 6 mm ID stainless steel with guard ProteCol HPLC column
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 4 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Waters Corp Spherisorb Silica Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
The Spherisorb silica chemistry is general purpose unbonded silica substrate designed for normal phase applications.
