solutions for your operations in gases and plasmas Q-MACS Process DC technical specification The Q-MACS Process DC is a portable monitoring system for on-line measurements of industrial processes, where the measurement equipment’s installation in the process room is not possible. This open path system uses mid-infrared absorption spectroscopic methods to determine absolute molecular concentrations. It is based on the Q-MACS Basic and features a dual channel setup, which allows the simultaneous measurement of multiple species. The long-term stability for broad absorption features was improved by adapting normalization concepts. general description dual path infrared spectrometer with two IR-light sources response time time resolution down to milliseconds, sub-microsecond time resolution on request components parts ▪▪ optical board ▪▪ industrial PC with acquisition hardware ▪▪ electronic supply system ▪▪ water cooling system parameter power ▪▪ 230 V, max. 2 A (switch-on current 6 A) ▪▪ 115 V, max. 4 A (switch-on current 12 A) working range ▪▪ inter pulse mode (laser sweep mode) ▪▪ intra pulse mode (single pulse mode) pulse width 8 ns* … 256 ns** * depends on the QCL and QCL-voltage used ** longer pulses on request pulse frequency
