HPLC Guard Columns and Cartridges
Optimize Technologies EXP Trap Cartridge, 2.1mm x 5mm, 3.0µm EXP, 3.0µm EXP, SAX, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.

Optimize Technologies EXP Guard Column Cartridge, 4.6mm x 5mm, C4, 1.8µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
Mac-Mod Princeton HA-DHP (Dihydroxypropyl) 100 Å, 5 µm, 4 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!
Waters Corp ACQUITY Premier BEH Amide VanGuard FIT Cartridge, 1.7 µm, 2.1 x 5 mm, 3/pk;
ACQUITY Premier BEH Amide VanGuard FIT Cartridge, 1.7 µm, 2.1 x 5 mm, 3/pk;
Mac-Mod Avantor Prevail C18-Select, 110 Å, 5 µm, NA x NA mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.

Optimize Technologies OPTI-MAX Outlet Cartridge Check Valve, 1/8" Ceramic Ball & Seat, Stainless Steel Cartridge, Shimadzu LC-8A
Opti-Max™ Cartridge Check Valves are designed to offer maximum performance and ease of use. From the sharp, consistent threads on OPTI-MAX™ custom housings, to the exacting standards used to match ball/seat sets in OPTI-MAX™ cartridges, every aspect of design and manufacturing reflects an unavoidable fact: when it comes to reliable check valve operation, quality and precision make a big difference. OPTI-MAX™ check valves offer many advantages over OEM check valve systems, and are better designed, better made and more reliable than any other after-market check valve product. Additionally, OPTI-MAX™ Free-Turn™ housings can be removed with the tubing still attached, accelerating check valve maintenance while reducing fitting wear. This item is equivalent to OEM part number
Waters Corp Symmetry Shield RP18 Sentry Guard Cartridge, 100Å, 5 µm, 3.9 mm X 20 mm, 2/pk
These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP18 column significantly improves peak shape and resolution.
Waters Corp µBondapak C18 Radial-Pak Column, 125Å, 10 µm, 8 mm X 100 mm, 1/pk
µBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 µm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between resolution, throughput and cost.
Waters Corp SunFire C8 Sentry Guard Cartridge, 100Å, 5 µm, 4.6 mm X 20 mm, 2/pk
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
