ET070 Hydroflex™ – 水素比較電極
 

 

従来、水素比較電極は白金黒片上に水素ガスを曝しながら使う必要がありました。 電極ボディー内の気泡の作用が重要で、このため常時水素ガスボンベから水素を供給する必要があり、利便性やコスト、安全性の面で問題がありました。そこで長年、代用となるべく基準電極の出現が待ち望まれていました。

Hydroflex電極は内部に交換可能なカートリッジが付いており、常時僅かな水素を白金黒ガス拡散電極に流しています。従って、比較電極本体も小型で外部から水素ガスを補充する必要は全くありません。

Ag/AgCl電極やカロメル電極などの比較電極として使用する電極の基準電極として、またはこれらの電極が使用できない溶液を扱う場合に最適です。特に水素は、水溶液やアルカリ性溶液中では比較電極として最適な特性を持ち、高圧下(~10 bar )に於いても、高温下(210℃)でも安定して使用できます。
