  • Page 9: Introduction

    1.1 Instrument description 1 Introduction Instrument description The 761 SD Compact IC is a version of the time-proven 761 Compact IC which has been developed specifically for soft drink analysis. The 761 SD Compact IC is designed for determining phosphoric acid and its intermediate products in soft drinks but also continues to offer all functionalities of the original version.
  • Page 10 Ready-to-use eluents in certified MPaks are supplied for soft drink analysis. The 761 SD Compact IC is operated by means of a PC connected to the RS232 interface. The 761 SD Compact IC can be controlled by the «IC Net» software or by the “master” «IC Cap» software.
