在高效液相色譜分析系統中，正確的控制色譜柱的溫度，對于提高柱效、改善峰分離度、保證重現性、以達預期的分析結果，具有不容忽視的作用。HT系列色譜恒溫箱采用原裝進口溫控器和傳感器，具備PID智能自整定、上限超溫報警、自動斷電功能，系統溫控精度高且操作方便安全。 Valco 高壓開/關閥或裝填/排放閥具有工藝精湛、加工精密和內體積極小(< 2 μl)的特點，是大多數要求苛刻的液相色譜、超臨界色譜或萃取系統理想的選擇。開/關閥的功能不用解釋了；對于裝填/排放閥，當閥關閉時流動相流到針頭周圍，降低了來自色譜柱的背壓。當閥打開時，流動相被排放掉。 操作溫度在100°C 時，標準類型能提供壓力最高達10,000 psi (690 bar)的密封操作。操作溫度在300°C 時，高溫類型的最高耐壓為6000 psi 。采用大孔徑1/16" 接頭的開關閥和采用1/8"接頭的開關閥可以在高流量應用中使用。 閥針由特殊的高強度合金制造，甚至能抗偶然在閥中沉降的緩沖鹽的腐蝕。密封采用碳化合物，閥體由HPLC 規格的不銹鋼加工制造，即使是在最惡劣的環境中也能確保很長的使用壽命。 開/關閥或裝填/排放閥有手動和空氣/二氧化碳氣體驅動兩種類型。氣動閥需要使用一個電磁閥：用50 psi 壓力的氣體打開閥；放掉空氣后彈簧使閥返回到關閉的位置。開/關閥接頭規格孔徑手動貨號手動帶 4" 加長桿貨號氣動帶 1" 加長桿貨號氣動帶 4" 加長桿貨號標準溫度型1/16"0.50 mmSFVO?ASFVO?0.75 mmSFVOL?ASFVOL?高溫 / 高壓型1/16"0.50 mmSFVOHTSFVOHT4ASFVOHTASFVOHT40.75 mm??ASFVOLHTASFVOLHT41/8"1.50 mm??ASFVO2HTASFVO2HT4裝填/排放閥接頭規格孔徑手動貨號手動帶 4" 加長桿貨號氣動帶 1" 加長桿貨號標準溫度型1/16"0.50 mmSFVASFV?0.75 mmSFVLASFVL?高溫 / 高壓型1/16"0.50 mm?ASFVHTASFVHT40.75 mm?ASFVLHTASFVLHT41/8"1.50 mm?ASFV2HTASFV2HT4規格接頭溫度壓力標準溫度型1/16"100oC10,000 psi高溫 / 高壓型1/16"300oC6,000 psi1/8"300oC2,000 psi◆ 1/16"Valco無死體積 接頭，孔徑0.4 mm 孔(.016") HPLC柱選擇系統☆ 最大壓力5000 psi（液體）最高溫度75oC金屬定子Valcon H轉子☆ 最大壓力5000 psi（液體）最高溫度50oCPAEK定子Valcon E轉子l 包括定子材質的不銹鋼螺母和壓環。lPAEK定子材質的閥備有PEEK螺母和壓環。l 微型電驅動器：24VDC, 帶 110/230 VAC轉 24VDC 變壓器。◆ 選擇:l 2"、3"、4" 和6" 加長桿。l Hastelloy C合金定子l 可選擇 0.25 mm (0.010") 孔。l 制備型HPLC可選擇0.75 mm (0.030") 孔。產品結構特點:1. 干式加熱(HGC系列)和水浴加熱(HSC系列)兩個系列,可滿足不同用戶的使用需求.2. 數字溫控器,雙數字顯示,調節采用PID技術并可實現超溫報警.3. 分配室上各氣針通道可組合使用或單獨使用,分配室的高度可視需要調節.4. 可能與溶劑接觸的部件均采用316不銹鋼材料、合金鋁、或表面進行塑料噴涂，使用壽命更長，清潔更方便。5.

Flow Adapter for Standard Column
用途：	能傳送樣品或緩沖液直接到凝膠床頂部以提高色譜分辨率。用于緩沖液梯度、逆流情況或高分辨率重力分離。
簡介：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.

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 .
