Fig. 4. represents a characteristic sample from
one of Hajdúszoboszló’s hot springs. This sam-
ple is practically full of peaks in the RT range un-
der study (128/100 peaks, total area: 10,905,727
counts). Further analyses with Hajdúszoboszló
water were focused on the ready-to-use, phys-
ically treated (mixed and cooled) spa samples.
The stability of the volatile compounds was
also checked by comparison of the peaks ex-
tracted from the fresh and stored (72-hour) iso-
lates. Meanwhile peak number decreased from
125/98 to 86/61, and total area from 18,121,858
to 4,577,592 counts, some characteristic peaks re-
mained unaltered after the three-day storage at
ambient temperature representing some stable and
permanent components of the sample.
