Liquid Chromatography - Sample Preparation

Sample preparation is key but often overlooked step in the chromatography process. Every sample is unique and what works for one preparation may not work as well for another. That’s why Avantor offers a comprehensive range of products.

Avantor equipment and products for sample preparation

Syringe Filters

Thoroughly filtering samples can help keep your chromatography system working well and extend column life. Avantor carries a wide range of products so you can choose the correct membrane, material, and pore size for every sample you use. See what we have.

Solid Phase Extraction

Solid phase extraction (SPE) is a key step in separating the compounds that make up a sample mixture so they can be analyzed. Look at Avantor’s selection of SPE products for your laboratory.


You need to reduce undissolved particulates in your sample and analyse the supernatant. The use of a centridfuge is a good first step.

Heating and Stirring

Prepare your samples or your mobile phases in one of the hot plate stirrers or reaction stations available from Avantor.

Measuring Apparatus

If you work in chromatography, you need reliable pH meters, balances, pipettes, and other measuring devices. Avantor carries a comprehensive range of products to meet all your needs.

High Purity Salts and Acids

If your sample preparation requires a reaction step, make sure you use a high-quality reagent from Avantor.
