Sensors launches SEMTECH LASAR spectrometer

23 June 2011

Sensors announced the launch of a new SEMTECH LASAR line of emission analyzers. The SEMTECH LASAR is an optical feedback, cavity enhanced, laser absorption spectrometer, capable of measuring both trace levels and high concentrations of a wide range of gases, including NH₃, NO, N₂O, NO₂, H₂S, SO₂, SO₃, H₂, O₂, as well as several aldehyde, alcohol and hydrocarbon species with one or two carbon atoms.

This multigas analyzer has been designed with no moving parts, hygroscopic optics or liquid N₂ cooling, that may be required with other types of instruments, such as FTIR. Therefore, the analyzer is suitable for both test cell and on-board vehicle applications. Sensors emphasized a number of features of the instrument:

• A low pressure sampling system enables fast response (> 1 Hz) analysis of hot gas mixtures with high moisture content without the need for sample conditioning.
• Cross interference is controlled by coupling 1 picometer optical resolution with low pressure operation.
• Use of non-fibered lasers enhances spectral range selection, dynamic range of calibration and enables the simultaneous measurement of both trace and high concentrations of analytes.

The SEMTECH LASAR can be operated through a touch-screen control panel or host software. Live data can also be monitored remotely from the internet, for immediate access to results, diagnostics and raw signal information.
