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.
wvs columns: engineered to provide unsurpassed consistency and longevity
partisil irregular mediaavailable 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 mobile phase modifiers.
partisphere spherical mediaavailable 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 rtfpartisphere 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.
partisphere and partisil 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).
