          Partisil and PartiSphere Void Sealing (WVS) Columns 空隙密封色譜柱的詳細介紹
          Partisil and PartiSphere Void Sealing (WVS) Columns 空隙密封色譜柱

          Whatman WVS columns are renowned for their high quality, innovative design, and 
          exceptional durability.
          WVS columns allow easy adjustment of the top frit to fill the void that 
          gradually develops and reduces resolution as silica dissolves.
          Features and benefits 
            Void sealing columns can last twice as long as standard end fitting columns, 
            saving as much as 50% on column cost per test
            Available packed with spherical and irregular media
            Integral void sealing mechanism prolongs column life
            Reusable, hand tightened end-fittings save money, allow for wrenchless 
            installation and rapid column changes
            Optimum resolution - typical column efficiencies for: 

              – Partisil 10 μm media: 45 000 N/m
              – Partisil 5 μm media: 65 000 N/m
              – PartiSphere 5 μm media: 90 000 N/m
          WVS Columns: Engineered to Provide Unsurpassed Consistency and Longevity
          Partisil irregular media
          Available in prepacked, replaceable columns and a choice of 5 μm and 10 μm 
          phases. These include silica and our popular ODS-3 and ODS-2 packings. Also 
          available are SAX (Strong Anion Exchanger), SCX (Strong Cation Exchanger) and 
          PAC (Polar Amino Cyano).
          Due to the greater surface area of the irregular Partisil, the medium offers 
          enhanced selectivity and loading capacity. Through uniform particle sizing, back 
          pressure is minimized. Also, the neutral pH of Partisil provides for better peak 
          symmetry without the need for phase modifiers.
          PartiSphere spherical media
          Available in prepacked columns and a choice of 5 μm high performance phases. In 
          addition to its efficient pure silica and monomeric C-18 and C-8, Whatman has 
          added SAX, SCX and PAC. PartiSphere media feature narrow particle size 
          distribution and excellent reproducibility.
          PartiSphere RTF
          PartiSphere Reduced Tailing Factor (RTF) HPLC columns contain base-deactivated 
          C-18 media. They employ a proprietary process that effectively ‘deactivates’ the 
          secondary chromatographic effect due to residual silanols. In addition, these 
          columns are extremely stable and can be used from pH 2 to pH 8 with no loss in 
          performance. Excellent for separation of basic compounds without the need for 
          amine-modified phases.
          Features and benefits 
            PartiSphere columns perform reproducibly every time, thanks to multiple 
            quality control tests for both primary and secondary separation mechanisms
            Polished internal column walls ensure packing symmetries and efficiencies
            PartiSphere RTF employs a proprietary process that effectively ‘deactivates’ 
            residual silanol groups
          PartiSphere and Partisil media are described in the HPLC media section.
          Note: Use of WVS columns requires a one-time purchase of WVS end fittings 
          (catalog number 4631-1001).
