HPLC Guard Columns and Cartridges
Waters Corp Nova-Pak C8 Guard-Pak Insert, 60Å, 4 µm, 10/pk
The 4 µm small particle size of Nova-Pak bonded phases offers high resolution, more efficient and faster chromatography by using shorter columns, reducing solvent consumption or by using longer columns to resolve even the most complex mixture. Semi-preparative columns with 6µm particle size packings give you an unparalleled range of separation possibilities. Stringent QC procedures in our cGMP manufacturing facility ensure batch-to-batch reproducibility.

Optimize Technologies EXP™ Pre-Column Filter Cartridge, 0.5µm, 10pk
The EXP™ Pre-Column Filter is ideal for protecting small-particle UHPLC columns at extreme pressures. Such techniques analyze samples in the most demanding applications, which can decrease the life of these expensive columns. EXP™ Pre-Column Filters help extend that life and protect your column investment without sacrificing performance. Free-Turn¨ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. EXP™ Pre-Column Filter holders are available with Titanium Hybrid ferrules for easy direct connection to any 10-32 port. The filter holder comes as a complete package including fittings to provide repeated zero-dead volume column connections. Use with holder part number 15-04-03837.
Waters Corp Viridis BEH VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
Designed and tested for the ACQUITY UPC2 system, the Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
