Flow Adapter for Standard Column

用途：

能传送样品或缓冲液直接到凝胶床顶部以提高色谱分辨率。用于缓冲液梯度、逆流情况或高分辨率重力分离。

简介：420836

CHROMAFLEX Flow Adapters allow easy adjustment of the column bed volume. They are ideal for concentration ａnd pH gradients, reverse flow separations, ａnd gravity flow separations that require a high level of resolution ａnd reproducibility. Flow adapters are available for all three standard ID columns. Flow Adapters improve chromatogram resolution by delivering the sample ａnd buffer directly to the top of the gel bed. This protects the gel bed from disruption during sample loading ａnd eliminates any dead volume above the gel bed. Flow adapters are recommended when using buffer gradients, during reverse flow applications, ａnd for high resolution gravity flow separations. Each flow adapter is supplied with a 20 µm porosity HDPE bed support, TFE/propylene o-ring seal, stainless steel adjusting rod, PTFE body ａnd 5 feet (1.5 meters) of FEP Teflon® tubing. Use of aggressive organic solvents requires the accessory PTFE bed supports ａnd Kalrez® o-rings listed.

alchemyTM HPLC Columns The Queen of Beauty in Chromatography A Major Advance in HPLC Columns through NanotechnologyalchemyTM HPLC columns are made of spherical silica particles manufactured of the highest purity (〉99.999%) in the market. The highest quality silica, an innovative surface nano-modification and unique bonding processes result in exceptional C18 phases with outstanding properties. One of the most remarkable properties of every alchemyTM column is that all types of organic compounds (neutral, basic or acidic) will have perfect peak symmetry and excellent efficiency across the whole applicable pH range. The proprietary nano-surface modification generates a very smooth and non-reactive surface, reducing the interaction between the silica surface and polar compounds, especially the basic compounds. Lot-to-lot reproducibility is ensured by a stable bonding/end-capping process that is extremely rugged. The uniform, spherical particles have a nominal surface area of 360 m2/g with a controlled pore size of 100Å. All columns are packed using a consistent slurry packing process to achieve uniform and stable bed for maximum column efficiency, lifetime and column-to-column reproducibility.Unprecedented Experience in ChromatographyWith the alchemyTM columns, you will have an unprecedented experience in HPLC separation. Best peak symmetry and efficiency. This is one of the most remarkable features of our columns. They just outperform competitors’ products across the whole applicable pH range. Their peak shape and column efficiency are independent of pH. This provides maximum flexibility for method development and optimum ruggedness for the methods developed. Tightest specification. All our columns have tighter specification (see Table 2) than those of brand name manufacturers. This ensures that each column has great performance and identical se-lectivity. Best value. Because of our unique business structure and well-controlled processes, we are able to provide products of the highest quality at very competitive price; we are also able to customize any of our products based on customer requirements. Broad se-lection on prices and features. We offer a full line of products for a wide variety of applications and are willing to assist customers in optimizing their particular applications特征of alchemyTM columnsthe columns’用户效果Perfect peak symmetry, independent of pH and mobile phase Highest flexibility for any application,Better sensitivity,Greater confidence on HPLC results Broad pH range (1-10.5)Flexibility for method developmentCompatible with 100% aqueous mobile phaseMaximum versatilityHighest surface coverageTolerance of large volume and mass injectionA wide variety of chemistriesBroad se-lection of polarity and Maximum versatility Minimum buffer concentration neededBetter sensitivity for LC/MS, extended column lifetime Tightest specificationBetter reproducibility, Greater confidence on the HPLC resultsExcellent column efficiencyBetter and faster separationGreat column lifetimeLower cost; greater convenience Comparison of features and specification Waters Symmetry-C184.6 x 150 mm, 5umZorbax XDB-C184.6 x 150 mm, 5um alchemy XBP-C184.6 x 150 mm, 5umSpec. on efficiencyna800011000Spec. on tailing factor (toluene) na0.98-1.250.96-1.10Spec. on tailing factor-amitriptyline1.45na (typically 1.5-2.0)1.25Spec. on se-lectivity(amitriptyline/acenaphthene)+/- 10%na+/- 7%pH range2-82-91.5-10.5Specific Surface 300180360Carbon%16%12%22%Inertness and efficiency comparison Sample: uracil, toluene, doxepin , amitriptyline： Column: 4.6 x 150, 5 umMobile phase: 10 mM sodium phosphate (pH=7) in 60% ACN.Temperature: 30 oC; Flow（: 1 mL/min.

Due to special silica treatment, they are true C18 columns that are compatible with 100% aqueous mobile phase. Like XBP columns, they are still very friendly towards those very basic analytes. Although their upper pH limit is not as high as XBP, it is comparable to many popular brand name columns. alchemyTM LP-C18 columns are the most polar among C18 columns due to a polar end-cap and are preferred replacement for Waters Atlantis and Zorbax SB-C18. They are extremely stable at low pH and may also be used at mid-pH. Unlike Atlantis and SB-C18, LP-C18 columns can still maintain perfect peak symmetry even for very basic analytes and are compatible with 100% aqueous mobile phases.在 C18 columns中alchemyTM LP-C18 columns Comparison of alchemyTM -C18 PhasesXBP-C18AQ-C18LP-C18Surface area (m2/g)360360360C%22%18%17%End-capdoublesinglepolarPolarityIncrease àpH stability1.5-10.51.5-91-7100% water compatible noyesyesPeak shape of bases excellentexcellentexcellentReplacedcolumnsZobax XDBSymmetryXterraLunaDiscoverySymmetryLuna (2)Inertsil ODS-3AQ phasesZorbax SB-C18Zorbax SB-AQWaters AtlantisAQ phases Use of organic base for pH 〉 9 is recommended .
