Chemical Resistance
 Substances Extracted from Tag (Reference)
If chemicals penetrate into a Tag through PFA, ions may be extracted from the Tag.
 Results of Ion-exchange Chromatography
A built-in Tag was soaked in hot water (100°C for 16 houres), and extracted ions were analyzed. The
results are shown below.
Extracted Ions (Concentration)
Cl: 0.5 ppm, Na
+
: 10 ppm, NH4
+
: 11 ppm, K
+
: 1.0 ppm
 Results of ICP Emission Spectral Analysis
The V680-D1KP66T-SP Tag was soaked in condentrated hydrochloric acid (which can easily penetrate
through PFA) at 80°C fo 300 hours, then extracted substances were analyzed.
Extracted Substances (Concentration)
Si: 700 ng/ml, S: 1,000 ng/ml, Ca: 30 ng/ml
The chemical resistance and extracted substances presented here should be used for reference only. The
rates of change in Tag characteristics and the amounts of substances extracted will vary with temperatures
and chemical concentrations. Before using Tags under actual production environment, always conduct tests to
check for any problems
