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, andexceptional durability.WVS columns allow easy adjustment of the top frit to fill the void thatgradually 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/mWVS Columns: Engineered to Provide Unsurpassed Consistency and LongevityPartisil irregular mediaAvailable in prepacked, replaceable columns and a choice of 5 μm and 10 μmphases. These include silica and our popular ODS-3 and ODS-2 packings. Alsoavailable are SAX (Strong Anion Exchanger), SCX (Strong Cation Exchanger) andPAC (Polar Amino Cyano).Due to the greater surface area of the irregular Partisil, the medium offersenhanced selectivity and loading capacity. Through uniform particle sizing, backpressure is minimized. Also, the neutral pH of Partisil provides for better peaksymmetry without the need for phase modifiers.PartiSphere spherical mediaAvailable in prepacked columns and a choice of 5 μm high performance phases. Inaddition to its efficient pure silica and monomeric C-18 and C-8, Whatman hasadded SAX, SCX and PAC. PartiSphere media feature narrow particle sizedistribution and excellent reproducibility.PartiSphere RTFPartiSphere Reduced Tailing Factor (RTF) HPLC columns contain base-deactivatedC-18 media. They employ a proprietary process that effectively ‘deactivates’ thesecondary chromatographic effect due to residual silanols. In addition, thesecolumns are extremely stable and can be used from pH 2 to pH 8 with no loss inperformance. Excellent for separation of basic compounds without the need foramine-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 groupsPartiSphere 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).
