Partisil and PartiSphere Void Sealing (WVS) Columns 空隙密封色谱柱的详细介绍
Partisil and PartiSphere Void Sealing (WVS) Columns 空隙密封色谱柱

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).
