Development of Melting System for Measurement of Trace Elements and Ions in Ice Core
We present a titanium (Ti) melting head divided into three zones as an improved melting system for decontaminating ice‐core samples. This system was subjected to performance tests using short ice‐core samples (4 × 4 cm 2 , ~5 cm long). The procedural blanks (PBs) and detection limits of ionic specie...
