General description
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. Void sealing columns can last twice as long as standard end fitting columns, saving as much as 50% on column cost per test.
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 mobile phases.
Features and Benefits
Note: Use of WVS columns requires a one-time purchase of WVS end fittings (catalog number 4631-1001).

Features and Benefits
- Partisil and 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).
