NUCLEOSIL® is a family of totally porous spherical silicas with a very pure and uniform SiO2 structure
- Wide acceptance as routine packings for very different fields of chromatography
- One of the first spherical silicas used in HPLC
- Developed in the early seventies, it became a world-renowned HPLC packing
- Still found in many analytical and preparative application
- An absolutely reliable choice in HPLC
- The largest variety of modified HPLC silicas available on the market
NUCLEOSIL® 100-5 C18 PAH
Special octadecyl-modified (ODS) silica phase for HPLC analysis of PAHs
USP L1
Features
- Base material NUCLEOSIL® silica
- Particle size 5 µm
- Pore size 100 Å
- Polymeric coating
Eluent in column acetonitrile – water (70:30, v/v)
Allows efficient gradient separation of the 16 PAH 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.)
