 Substances Extracted from Tag (Reference)
If chemicals penetrate through PFA into the Tag (V680-D1KP66T) built into the V680-D1KP66T-SP,
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 hours), and extracted ions were analyzed. The
results are shown below.
Extracted Ions (Concentration)
Cl: 0.5 ppm, Na
+
: 10 ppm, NH4

: 1.0 ppm
 Results of ICP Emission Spectral Analysis
The V680-D1KP66T-SP Tag was soaked in concentrated hydrochloric acid (which can easily penetrate
through PFA) at 80°C for 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.
