Bioanalysis requires a lot of flexibility in the pore size, the pH range, the temperatures and the solvents used. To achieve this, we cross phase limits. Learn More

Applications

Peptides exceeding approximately 50 amino acids and oligonucleotides greater than 25 residues

Pore Sizes

300 or 100-1000 Å

Particle sizes

3–10 µm

Improve your analysis of large molecules

Eurosil Bioselect columns for HPLC feature a wide pore stationary phase and were specifically designed to separate large biomolecules, such as proteins and peptides. Eurosil Bioselect columns are available in four modifications for separations of large molecules up to 100 kDa.

AppliChrom® RPeptide columns are reversed phase (RP) columns with a polymer base instead of silica gel. They offer a chemically highly stable alternative with orthogonal selectivity to well-known large-pore silica gel columns. If you are looking for a solution for your application with high temperatures and demanding pH requirements, you will find it here. These columns also offer very good long-term stability with consistently high performance, particularly in the preparative field.

Headline headline head

I am a dummy copy. And I´ve been a dummy copy since my birth. It took me a long time to realize what it means to be a dummy copy: you make no sense. You stand out now and then by being completely out of context. Often, you aren´t even read at all.

But does that make me a bad copy? I know that I´ll never stand a chance of appearing in the Economist. But does that make me any less important? I´m a dummy! But I enjoy being a copy. And should you now decide to carry on reading me to the end, I´ll have managed to achieve something most „normal“ copies don´t achieve.
