Agilent Technologies' EZChrom Elite CDS and Agilent OL Operating System for the Laboratory are software systems well known for their comprehensive instrument control. In addition to software control of many commercial Gas Chromatographs, autosamplers and HPLC instruments, EZChrom Elite and Agilent OL can also control two position and Multi- position Microelectric Actuated valves from VICI AG (Valco Instruments Co, Inc) with optional instrument control software. This capability allows VICI valves to be integrated into an HPLC or GC instrument system for additional sampling control. The VICI Valve instrument control software option allows the software method to specify which stream position to use before the chromatographic run is started. Used in this way, the VICI Valve functions as a sampling device. By setting a delay between selecting a stream and staring a run, it is possible to optimize the cleaning of the sample loop of the injection valve. In addition to its use as a sampling device, the VICI valve may be used in a standard stream switching role. By entering commands into an EZChrom or Agilent OL method timed event table, multiple valves can be switched during the chromatographic analysis.
The Agilent VICI Valve Control Software for EZChrom Elite CDS enables the control of VICI AG (Valco Instruments Co, Inc) microelectric actuated valves. This software option allows the EZChrom Flite and Agilent OL Operating System to specify stream positions before a chromatographic run starts, functioning as a sampling device. It also supports standard stream switching roles where multiple valves can be switched during analysis via timed event tables.
| Supported Valves | EMHA 2-position valves, EMHCA Multi-Position, EMTCO Multi-Position |

It allows the software method to specify which stream position to use before the chromatographic run is started, functioning as a sampling device.
Yes, by entering commands into an EZChrom or Agilent OL method timed event table, multiple valves can be switched during the chromatographic analysis.
No, the software has restrictions and is not configurable in combination with a standard sampler.
