Chromatography

As I mentioned in the last post from this series, capillary columns of 10–100 μm inner diameter are commonly used in nano-liquid chromatography setups. They are typically made either from fused silica or PEEK materials currently found in your everyday Gas Chromatography or HPLC, respectively. There are three basic types of capillary columns used in […]

It is interesting to note that 20 years later there is still no clear definition of nano-LC. Due to a relatively large size of the columns used in nano-HPLC (10-140 μm), the method does not fall within the realm of the conventional definition of nanotechnology – “the control of matter on a scale smaller than […]
