If chemicals penetrate into the built-in Data Carrier through PFA, ions may be
extracted from the Data Carrier.

Results of Ion-exchange Chromatography
The built-in Data Carrier was soaked in hot water (100
C
for 16 hours), and
extracted ions were analyzed. The results are shown below.

Results of ICP Emission Spectral Analysis
The V600-D23P66SP Data Carrier was soaked in concentrated hydrochlo-
ric acid (which can easily penetrate through PFA) at 80
C
for 300 hours,
then extracted substances were analyzed.
