  • Page 9: Introduction

    A level sensor for the eluent bottle is indispensable for the automated pro- duction of eluent and is contained in the scope of delivery of the 941 Elu- ent Production Module. However, we recommend using level sensors to also monitor the bottle with the concentrate and the ultrapure water con- tainer.
