Formaldehyde is both a non-coagulant and an additive fixative. Formaldehyde is known to penetrate tissue quickly, but the fixation process may take a long time to form the various cross links with tissue proteins. Formalin fixation is thought to form cross links between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining. Although there is no true universal fixative, 10% neutral buffered formalin (NBF) is perhaps the most commonly used fixative throughout the world for light microscopy and is a somewhat forgiving fixative. Of the dozens and dozens of available fixatives, it is hard to imagine a fixative more commonly used than 10% NBF. 10% neutral buffered formalin is well suited for large throughput laboratories, and requires a relatively short period of fixation, but can also be used for the long-term storage of tissue.

The Avantor® ACE® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Supplier: Avantor

Avantor® ACE® HILIC method development kits offer all three Avantor® ACE® proprietary HILIC phases (HILIC-A, HILIC-B and HILIC-N) in one kit. These phases offer alternative HILIC selectivity to each other, and have been developed to enable chromatographers to achieve reproducible and successful HILIC separations using a systematic approach to method development.

Supplier: CHIRAL TECHNOLOGIES

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%.
