​“ 機能の追加

★ PURGE 機能 
高速送液を行えます。稼働時間を設定できるので液が枯れる心配はありません。
エア抜き、液交換を自動で行えるので一般的なHPLC のトラブルで最も多いポンプによるエラーが大幅に改善されました。

★ TIMER 機能
ポンプ、ECD それぞれを時間制御でON/OFF する機能です。稼働時間を制限できるので移動相の消費を最小限に抑える事が可能です。
このTIMER 機能によってポンプやECD を効率的に稼働させスムーズなサンプル測定へ移行する事が出来ます。

★ L.SWITCH
HTEC-600 からELS-500 を制御する事が可能です。アミノ酸分析や比較的夾雑が出やすいサンプルの場合クロマトグラム後半に
出てくる夾雑を除去することは分析の効率化につながるので、ELS-500を手軽に使用できることは実験する上で大きなメリットとなります。

作用電極の洗浄や交換・メンテナンスが容易
 

コンパクトでシンプルな設計の為、作用電極の交換をするのに工具は不要です。
またメンテナンスが驚くほど容易です
