Optimize Technologies OPTI-PAK™ Trap Column, 0.12µL, SAX, 5pk
The OPTI-PAK™'s unique hardware design integrates a PEEK holder with an auto-adjusting stem which provides a fluid interface with any 10-32 standard injector port, and guarantees a zero-dead-volume connection despite variances in tube stop depth. A proprietary method of frit placement allows the packed stem to be positioned directly into the flow path, which eliminates all excess swept volume. Less swept volume translates to absolute minimum sample dilution and dispersion. The elegant, flexible design of OPTI-PAK™ makes it amenable to virtually any trapping application. Installing an OPTI-PAK™ into the outlet of a switching valve will facilitate the trapping, desalting, and pre-concentration of an analyte mixture. With OPTI-PAK™s versatility, a second trap can be added downstream in the loop of an injection valve and effectively perform a 2D separation.

Sepax Technologies Inc Sepax HPLC Column PolyRP-500, 5 µm, 2.1 x 250 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Waters Corp Waters Column, XSelect CSH C18, 3.5 μm, 4.6 x 20 mm
XSelect CSH C18 columns are general-purpose columns that provide alternative selectivity compared to other C18 sorbents. They incorporate Charged Surface Hybrid (CSH) technology, which helps to mitigate common column-related issues.
- Can be used as general purpose columns, offering alternative selectivity compared to other C18 sorbents.
- Utilizes Charged Surface Hybrid (CSH) technology.
- Addresses issues such as peak shape asymmetry and poor loading for basic compounds.
- Reduces column bleed and slow mobile-phase re-equilibration.
YMC America, Inc CN 300A 5um 5x0.5mm 1/16
YMC-Pack CN can be used for both normal phase and reversed phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle It can be used in normal phase with low-polarity mobile phases such as hexane or in reversed phase with highly-polar mobile phases such as methanol and water YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8 or when separation optimization is difficult
Sepax Technologies Inc Sepax HPLC Column GP-C4, 10 µm, 120 Å, 10 x 50 mm
Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
YMC America, Inc Jsphr H80 80A 4um 5x.5mm 1/32
The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization
Microsolv Technology Corporation HPLC Column, RP C18, Wide Pore, 5um, 2.1mm ID x 100mm Length, 300A. 1 EA.
This Cogent RP C18™ Wide Pore Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is double end capped ( fully ), with traditional bonding of an 18 carbon silane to the highest purity silica available.With a 5 µm Particle and 300A Pore Size, this column works well with higher flow rates and lower back pressures. Used for large hydrophobic or neutral compounds in Reversed Phase, this Octadecyl Phase is also excellent for long chain fatty acids, some proteins and peptides. This column is often chosen for LCMS when increased resolution is desired.
