Q-MACS Trace

Q-MACS Trace

Product catalog summary
Overview: The Q-MACS Trace is a portable system designed for high sensitivity trace gas measurements using infrared absorption spectroscopy. It is adaptable with different optical long path cells based on the required sensitivity.
General Description: The system is a single path infrared spectrometer equipped with an IR-light source and a long path cell. It offers sensitivity down to the parts per billion (ppb) range and time resolution down to milliseconds. The dimensions are 700 mm x 1240 mm x 450 mm, and it weighs 125 kg.
System Versions: The Q-MACS Trace is available in several versions based on the length of the long path cell: 3.6 m, 5.4 m, 7.6 m, and 10.0 m.
Components: The system includes an optical board, a laptop with an external PCI-card box, a Herriot cell, a vacuum pump system, and a water cooling system.
Parameters: The power requirements are 230 V with a maximum of 2 A (switch-on current 6 A) or 115 V with a maximum of 4 A (switch-on current 12 A). The working temperature range is from +5 °C to +40 °C.
QCL (Quantum Cascade Laser): The tuning methods include inter pulse mode (laser sweep mode) and intra pulse mode (single pulse mode). The pulse width ranges from 8 ns to 256 ns, depending on the QCL and QCL-voltage used, with longer pulses available on request. The pulse frequency can reach up to 1 MHz, and the QCL temperature range is from -35 °C to +40 °C. The QCL is tested and installed.
Applications: The Q-MACS Trace is suitable for operations in gases and plasmas, with sensitivity depending on species, temperature, and pressure.
