Enhanced performance rackmount gas analyzers

GLA331 series

lRugged, sensitive, precise, accurate, highly linear (wide dynamic range) and fast.

Pre-calibrated gas analyzer with enhanced thermal stability to provide ultra-stable and minimal drift measurements in an 9U rackmount package that can handle fast pumpover timeswith fast-flow option and appropriate external pumps.

Overview
Specification

The analyzer is easy to use, low power and rugged which makes it ideal for a wide variety of field and air quality studies. The ability of the analyzer to simultaneously measure several gases at high speed and over a wide range of mole fractions makes it an excellent choice for eddy covariance flux and chamber flux measurements.  In addition, the instrument automatically reports gases on a dry (and wet) mole fraction basis (accurately corrects for water vapor dilution and absorption line broadening effects) by analyzing high resolution lineshape measurements without any need for sample drying or post processing.

ABB “Enhanced Performance" series incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy, linearity, stability and drift.  Moreover, only ABB analyzers provide reliable measurements (guaranteed) at concentrations more than 20 times greater than typical ambient levels.  Furthermore, ABB analyzers report measurements over the widest range of ambient temperatures allowing users to easily record reliable data in the field.

The analyzer uses ABB's patented Off-axis ICOS technology, a fourth-generation cavity enhanced laser absorption technique. Off-axis ICOS has many advantages over conventional optical techniques (including first generation cavity ringdown spectroscopy) such as being more rugged and alignment insensitive, having a much shorter measurement time, and providing measurements over a much wider dynamic range.

The analyzer has an internal computer that can store data practically indefinitely on its hard disk drive and send real time data to a data logger via the digital (RS232), analog or Ethernet outputs. It can be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser practically anywhere Internet access is available. Furthermore, full remote access provides the opportunity to obtain data and to diagnose the instrument operation without being on site.
