HALO® PAH
For the analysis of polycyclic aromatic hydrocarbons (PAH)
Polycyclic aromatic hydrocarbons (PAH) are aromatic compounds, which contain two to seven hydrocarbon rings. PAH result in the environment from natural processes (forest fires, volcanic eruption) or from incomplete combustion of organic material such as wood, coal, oil or tobacco. PAH are well soluble in fat and oil and bind to dust particles; they concentrate in organisms and the environment.
Consumers get in contact with PAH via contaminated rubber and plastic products, abrasion from rubber products, floor covering or wood preservatives. The human body is affected by PAH through tobacco smoke, air containing PAH and the consumption of contaminated food such as grilled or smoked food.
PAH are everywhere and can be carcinogenic, mutagenic and/or toxic to reproduction. Because of this significant environmental impact, methods for their detection were defined.
The HALO® Fused Core® column with trifunctional C18 bonded phase
was especially developed for the fast and efficient separation of PAH compounds. It is an excellent choice for laboratories that analyse food and water samples for PAH compounds.
Advantages of the HALO® PAH Fused-Core® column:
- Excellent selectivity for PAH compounds
- Excellent reproducibility
- Efficient separation at low back pressure
- High resolution and very robust
- Ideal for EPA 610, EPA 8310 and EU 15+1 methods
Specifications of the HALO® PAH Fused-Core® columns:
Particle size: 2.7 µm
Pore size: 90 Å
C-conent: 9.9 %
Surface area: 135 m2/g
Modification: trifunctional, C18
pH range: 2.0 - 9.0
Temperature maximum:
60° C at low pH
40° C at high pH
Ideal for EU 15 + 1 Methods and EPA 8310/610 + 2
The HALO® PAH achieves a method specific, high efficient separation of 18 standard PAH compounds with a resolution value of at least 1.5 in less than 5 minutes for EPA 8310/610 + 2 methods.
