HPLC Guard Columns and Cartridges
YMC America, Inc ODS-AL guard 120A 3um 20x3mm
YMC-Pack ODS-AL is a non-endcapped high carbon load monomeric C18 phase It exhibits different selectivity from conventional ODS columns due to the use of not only hydrophobic interaction but also secondary interactions caused by silanol groups YMC-Pack ODS-AL is intended for use only in those situations where residual silanol activity is beneficial to the separation
YMC America, Inc Cell-C guard 10um 10x10mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes
YMC America, Inc Tri C8 120A 1.9um 5x2.1mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure

All Avantor ACE Excel columns are known for their excellent peak shape and batch to batch reproducibility. Columns are packed in 1000 bar UHPLC hardware. Note: Avantor ACE Excel UHPLC guard columns are available for all 1.7 and 2 µm particle sizes across all 2.1 mm - 4.6 mm column ID - Note: H0011 connects directly to the analytical column - Guard column cartridges are available in 3-packs. For 3 and 5 µm Excel columns use same guard systems used for Avantor ACE HPLC analytical columns.
Optimize Technologies OPTI-GUARD 1mm Guard Column, Anion Exchange (SAX), (Black 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.
Waters Corporation Sentry Guard Cartridge, Amide, 3.5 μm, 4.6 x 20 mm
These Sentry Guard Cartridges are designed to retain extremely polar compounds, such as carbohydrates and sugars. They feature a chemically stable, trifunctionally bonded amide phase, stable from pH 2 to 11, for separating polar analytes across a wide range of polarity and pKa.
- Retains extremely polar compounds (e.g., carbohydrates, sugars).
- Chemically stable, trifunctionally bonded amide phase.
- Stable across a wide pH range (2 to 11).
- Separates polar analytes with varied polarity and pKa.
- Protects analytical columns by trapping particulates and strongly retained compounds.
- Ideal for HILIC applications, including sugars, glycols, and polar compounds.
- Compatible with common HILIC solvents (e.g., acetonitrile, water with buffers).
YMC America, Inc OCTYL 3UM 200A 20X4MM PK/5
OC20S03-0204GC: Octyl, 3um, 200A, 20X4mm Cartridge, pk/5
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 5 µm, 200 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.
