solutions for your operations in gases and plasmas Q-MACS Trace technical specification The Q-MACS Trace is a portable system for high sensitive trace gas measurements using different optical long path cells which depend on the sensitivity required. It is based on the Q-MACS Basic and uses infrared absorption spectroscopy to measure absolute molecular concentrations. general description single path infrared spectrometer with IR-light source and long path cell time resolution system versions ▪▪ Q-MACS Trace 3.6 - 36 m Long Path Cell ▪▪ Q-MACS Trace 5.4 - 54 m Long Path Cell ▪▪ Q-MACS Trace 7.6 - 76 m Long Path Cell ▪▪ Q-MACS Trace 10.0 - 100 m Long Path Cell components parts ▪▪ optical board ▪▪ laptop with external PCI-card box ▪▪ Herriot cell ▪▪ vacuum pump 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
