Nano Stationary Phase (NSPTM) GC
Columns
The NSP-PAH columns are specifically developed
for fast analysis and complete separation of EU and EPA priority
PAHs. The columns are highly stable with a maximum operating
temperature limit (MOTL) of 360oC and unmatched
selectivity when compared to conventional stationary phase
columns.
They show ultra low bleed at retention times of
heavier PAH. All specified PAH elute below 320oC due
to short column lengths. Due to high temperature stability,
these columns can be used in oven temperature isothermal or
program modes up to 360oC.

All critical components specified in both EU and
USEPA methods are separated to comply with the monitoring
regulations. As shown in the chromatogram, specifically,
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) 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 lengths less than 12 meters.
To achieve your goals of fast PAH analysis,
superb selectivity, improved column lifetime or
increased laboratory productivity, NSP-PAH column is your
best choice. Please select NSP-PAH columns of the right
dimensions for your appropriate instrumentation to meet your PAH
analysis goals. Short columns of lengths 12 meter and internal
diameters of 0.18 mm, 0.15 mm and 0.10 mm are adequate to
achieve complete separation of EU and EPA priority PAH due to
the superb selectivity of nano stationary phase.
