The ASI-5000 is an optional accessory for the TOC-5000 which allows automated carbon analysis in multiple samples. Carefully refer to this manual when installing and using the ASI-5000 Autosampler for the first time. This manual describes in detail the ASI-5000, as well as functions and operations in the TOC-5000 which relate directly to use with the ASI-5000 as an integrated automated system. For details related to independent Operation of the TOC-5000, please refer to the TOC-5000 Instruction Manual.

The ASI-5000 is provided with or without the optional rinse pump. Functions and other descriptions pertaining to the rinse pump are also covered in this manual. These may be ignored for instruments which do not incorporate the rinse pump.
