polydimethylsiloxane (CAR/PDMS) fiber, which has been demonstrated
as an optimal fiber for the n-nitrosamine analysis in the
previous studies [4,14] was used. The setting on the SPME holder
assembly was changed to 3.6 scale units before injection into the
GC injector port. In order to find out the optimal condition of HSSPME
for the analysis of target n-nitrosamines, salting out effect,
extraction temperature, and time were evaluated. Both the SPME
manual holder and fiber were purchased from Supelco (Bellefonte,
PA, USA). Pooled cream samples, containing no amount of n-nitrosamines,
were prepared and stored below 20 °C for the
spiking experiments.
