Whatman WVS columns are renowned for their high quality, innovative design and exceptional durability.

 

Features and Benefits
• Void sealing columns can last twice as long as standard end fitting columns, saving as much as 50% on 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 wrench-less installation and rapid column changes
• Require no holder or module, meaning fewer  components, reduced cost

 

Optimum Resolution
Typical column efficiencies for:
• PartiSphere 5 µm media - 90,000 N/m

 

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 WCX (Weak Cation Exchanger) as well as SAX, SCX and PAC. PartiSphere media feature narrow particle size distribution and excellent reproducibility.

PartiSphere RTF
PartiSphere RTF (Reduced Tailing Factor) HPLC columns are base-deactivated columns. They employ a unique 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 mobile phases. PartiSphere RTF is available prepacked in Whatman Void Sealing (WVS) and Analytical (WCS) column configurations and in a choice of C-18, C-8 and cyano phases.

 

Features and Benefits
• All PartiSphere columns are guaranteed to 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 (Reduced Tailing Factor) employs a unique proprietary process that effectively ‘deactivates’
 the secondary chromatographic effect due to residual silanols
