            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.

            The connection between   the sprayer head ａnd the flask is made with a special screw thread ground   joint, connecting cap ａnd loosening ring. If the joint ever   "freezes" from reagent crystallization or residue formation, simply   unscrew the connecting cap back onto the unique loosening ring ａnd the joint   will easily come apart. These sprayers will operate on as little as 1 psi (0.07 kg/cm²) air pressure with optimal   results at 3-5 psi (0.21-0.35 kg/cm²).   The connecting cap, loosening ring ａnd o-ring should be removed before   autoclaving.

            Microcaps® are   ingeniously simple in concept ａnd in use. They are precision-bore glass   capillary tubes, cut to predetermined lengths, so that each capillary tube   will hold a known volume of fluid when filled. Microcaps are so inexpensive   that it is not impractical to dispose of each tube after use.                        Filling is simple. Capillary action - not externally   applied suction - draws the fluid into the tube. To dispense the fluid,   simply squeeze the bulb. No unusual skills or training required. Immediate,   professional results. Ideal for spotting preadsorbent TLC plates. Supplied in   packages containing one bulb assembly ａnd one dispenser vial with 100   micropipets. Volumetric tolerance is ± 1%

                        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’用戶效果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 .
