Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent in the Bond Elut™ range. It is the most popular SPE sorbent because of its extremely retentive nature for non-polar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.

These columns allow chromatographers to employ essentially any organic solvent as mobile phase to develop methods for the most challenging separations. These columns are available in a variety of particle sizes and offer great speed and column resolving power. Columns packed with 3 µm CSPs offer high speed separations and a reduction in analysis time and cost per sample. Columns, packed with 3 µm particles, may be used in conventional HPLC units without significant loss in performance, even with the smaller column dimensions.

Supplier: Ahlstrom-Munksjö

Ahlstrom-Munksjö’s qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions. High Purity hardened filter papers grades 1288 to 1291 are also produced from cellulose with an alpha content of nearly 100% resulting in an ash content of <0,1%.
