Waters Corp Carbohydrate Sentry Guard Cartridge, 60Å, 4 µm, 3.9 mm X 20 mm, 2/pk
The Carbohydrate Sentry Guard Cartridge is used to extend and prolong the lifetime for the Carbohydrate Cartridge Column by removing chemical and particulate contaminants from the mobile phase stream.
Waters Corp ACQUITY UPLC Protein BEH SEC Guard Column, 450Å, 2.5 µm, 4.6 mm X 30 mm, 100K - 1500K, 1/pk
Based upon the highly successful BEH particle technology, the ACQUITY UPLC BEH450 SEC 2.5 µm column is fully optimized for the analysis of proteins and their aggregates with molecular weights ranging from 100,000 to 1,500,000 Daltons, the total system solution will routinely deliver fast, accurate aggregate determinations up to 10 times quicker that traditional HPLC-based SEC methods.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT-10 SEC-2000, 10 µm, 7.8 x 50 mm
Utilizing proprietary surface technologies, SRT-10 and SRT-10C SEC phases are made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on high purity and mechanically stabilized 10 µm silica. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Our unique bonding chemistry, coupled with the maximized bonding density, allows SRT-10 and SRT-10C SEC phases to provide high stability and negligible non-specific interactions. SRT-10 and SRT-10C packings have large pore volume, resulting in high separation resolution. Typical applications for SRT-10 and SRT-10C columns include separation and detection of biological molecules and water-soluble polymers in aqueous buffers.
Advanced Materials Technology HALO 90 Å C18, 2.7 µm, 2.1 x 5 mm, Guard Column 3pk
HALO C18 columns made with innovative Fused-Core particle technology for excellent reproducibility and column lifetimes provide fast, high resolution separations. Available in three particle sizes and a wide range of column dimensions, HALO 90 Å C18 columns are optimized for high performance in HPLC, UHPLC, and LCMS small molecule applications.
Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 3.0 mm x 5mm, Guard Column 3pk
Built upon proven Fused-Core technology for speed and efficiency, the HALO PCS column products are positively charged surface chemistries designed to deliver improved peak shapes for basic compounds observed with standard Phenyl-Hexyl chemistry. Ideal for use with low ionic strength mobile phases, HALO PCS maintains peak symmetry at higher loading capacities and provides alternate selectivities from Phenyl-Hexyl bonded phases. The columns are optimized to deliver performance for reproducible, high efficiency LC and LCMS separations.
Waters Corp Nova-Pak C18 Radial-Pak Guard, 60Å, 6 µm, 40 mm X 10 mm, 2/pk
Nova-Pak HR C18 columns are silica-based, semi-preparative and preparative columns that are based on 6 µm particle technology. Compared to a 5 µm column, Nova-Pak HR columns offer higher resolution, more efficient separations, and faster chromatography.
Waters Corp DeltaPak C4 Radial-Pak Column, 100Å, 15 µm, 47 mm X 300 mm, 1/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
Waters Corp Bondapak C18 Radial-Pak Guard, 125Å, 15 - 20 µm, 25 mm X 10 mm, 2/pk
Bondapak C18 is available in two different particle sizes, 15-20µm and 37-55µm, providing easy method transfer from µBondapak through preparative scale up. If you are developing a new purification protocol, Bondapak provides the best balance between resolution, throughput and cost.
