1.8 µm particles for increased separation efficiency
NUCLEODUR® silica with 1.8 µm particle size Miniaturization in HPLC has a long history. It started in the early stage of HPLC development with the reduction of particle size from 10 µm via 7 μm to standard 5 µm – which is still the most widely used particle diameter in analytical HPLC – to 3 µm spherical particles which so far was the smallest particle size available for gaining higher theoretical plates and efficiencies. With the introduction of the 1.8 µm NUCLEODUR®particles researchers have turned over an exciting leaf in HPLC column technology.
All NUCLEODUR® premium phases are available with 1.8 µm particles
