SunFire Silica C18 Prep Guard Cartridge, 100à , 5 µm, 30 mm X 10 mm, 1/pk
Optimize Technologies OPTI-GUARD 1mm Guard Column, Cation Exchange (SCX), (White Label), 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.
Mac-Mod Princeton 2-Ethylpyridine 100 Å, 5 µm, 10 x 10 mm Guard Cartridges (5/pk)
Princeton Chromatography Achiral SFC columns are designed and manufactured in the US, well known for innovating novel and robust workhorse phase chemistries, for the analysis of achiral SFC applications. Princeton designs myriad phase chemistries to improve the selectivity and efficiency of SFC analysis. Known for originally innovating the 2-EP phase chemistry, explore what Princeton has to offer. Columns are available from analytical to preparative sizes and are available in a wide range of pore sizes, particle sizes, column ID's and lengths. If you do not see something that you want, please just ask!
Mac-Mod Avantor ACE UltraCore SuperPhenylHexyl, 95 Å, 2.5 µm, 2.1/3.0 x 5 mm UHPLC Guard Cartridges (3/pk)
Avantor ACE UltraCore solid-core (core-shell) particle columns are ideal for MS work offering improved signal intensity and maximum response. These columns combine high efficiency separations with low back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability. Solid Core particle technology provides higher efficiencies per unit back pressure as compared to sub-2-micron UHPLC columns. Columns combine the proven advantages of UHPLC and HPLC columns with Solid Core Particle Technology. Solid-core columns can be used on both UHPLC and HPLC systems. Excellent peak shape and phases stability with extended pH. Highly inert, ultra-low bleed, designed for use with LC/MS compatible buffers. 2.5 and 5 µm particle sizes available.
