NSP-PAH
Specifically designed for full and fast separation of all 25 PAH’s recognized under EPA method 610 and the EU protocol for PAH in foods.
Stationary Phase Properties:
- highly phenylated polar
- immobilized and chemically bonded
- temperature limits -0°C to 360°C
- low column bleed
The columns are highly stable with a maximum operating temperature limit (MOTL) of 360°C and unmatched selectivity when compared to conventional stationary phase columns. The NSP-PAH columns show ultra low bleed at the retention times of heavier PAH’s. All specified PAH’s elute below 320°C due to the shorter column lengths. Due to their high temperature stability, these columns can be used in isothermal or temperature program modes up to 360°C. The MOTL decreases with increase in column length and film thickness.
All critical components specified in both EU and USEPA methods are fully separated to comply with the monitoring regulations. As shown in the chromatogram, Phenanthrene is separated from Anthracene; Benzo(a)anthracene is separated from Chrysene; Benzo[b], Benzo[k], and Benzo[j] fluoranthene isomers are separated from each other; Benzo[a]pyrene is separated from Benzo[e]pyrene, and Perylene; Indeno[1,2,3-cd]pyrene, Dibenzo[a,h]pyrene and Benzo[ghi]perylene are separated from each other; also, Dibenzo(a,l) pyrene, Dibenzo(a,e)pyrene, Dibenzo(a,i)pyrene, and Dibenzo(a,h)pyrene are completely separated from each other.
Separation of the 25 component PAH mixture of both EPA Method-610 and EU protocol PAH (except Cyclopenta[c,d]pyrene and 5-Methylchrysene, currently not available) are demonstrated on conventional internal diameters (I.D.) of 0.18 mm and microbore columns (with I.D. 0.15 mm and 0.10 mm) of length less than 12 metres.

Application Chromatograms
The application chromatograms highlight novel performance demonstrations of J&K’s NSP-PAH GC columns. Analyses with application chromatograms of various samples under different conditions on NSP-PAH columns of different dimensions are for your review and to evaluate your next GC column purchase.
