REATORG OFFERS WELCH MATERIALS ON THE RUSSIAN MARKET

Welch Materials develops and manufactures Chromatography consumables including HPLC and UHPLC columns, Solid Phase Extraction (SPE) columns, GC columns, sample vials, syringe filters, and chromatographic media. Welch Materials products are well known as high quality and reliability.

Utilizing their deep experience in particle surface modification science, Welch Materials have developed many innovative products including five series of HPLC columns including Ultisil, Xtimate, Topsil, Welchrom, and Boltimate.

Ultisil Series HPLC Columns are based on ultra-pure spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development, owing to complete bonding chemistries and stable performance.

Ultisil series is represented by a lot of difference phases, for example XB-C18, XB-C8, XB-Phenyl, XB-C4, XB-C1, XB-CN, XB-SAX, XB-SCX, PAH, Polar-RP, AA-Amino Acid, etc.

Xtimate Series HPLC Columns offer more options: wide pH range from 1.0 to 12.5, excellent peak shape for strong bases, extra column lifetime, extra performance.

Topsil Series HPLC Columns are Welch’s Next Generation Silica, with larger pore size and greater surface area, and they are good for small molecules and peptides. TopsilTM C18 phase can also be used at 100% aqueous condition without phase collapse.

Welchrom Seires HPLC Columns use the same Ultra-high purity Type B silica found in all Welch silica-based stationary phases. It combines with bonding and endcapping steps exclusive to the Welchrom products to produce phases with slightly different selectivity than Ultisil or Topsil. Another positive point is also the economically priced of Welchrom series columns.

Boltimate Series HPLC Columns are based on a core-shell material with a 1.7 μm diameter non-porous solid core, and a 0.5 μm porous outer shell. This kind of column can provide great efficiency, high deliver speed and high resolution at much lower back pressure. Boltimate core-shell column can be used on both HPLC and UHPLC system, and method optimization is also very easy.
