NUCLEODUR® is a fully synthetical type B silica (silica of 3rd generation) offering highly advanced physical properties:
- Totally spherical particle shape
- Outstanding surface microstructure
- High pressure stability
- Low metal content
NUCLEODUR® as a state-of-the-art silica is the ideal base material for modern HPLC phases. It is the result of MACHEREY-NAGEL's pioneering research in chromatography for almost 50 years.
NUCLEODUR® C18 PAH
Special high-purity octadecyl-modified silica phase for HPLC analysis of PAHs, USP L1
Features
- Base material NUCLEODUR® silica
- Particle sizes 1.8 µm (UHPLC) and 3 µm
- Pore size 110 Å
- Polymeric coating
Eluent in column acetonitrile – water (70:30, v/v)
Allows efficient gradient separation of the 16 PAHs according to EPA Detection of the separated PAHs by UV (250 to 280 nm), with diode array or with fluorescence detection at different wavelengths for excitation and emission (Acenaphthylene cannot be analyzed with fluorescence detection.)
