ARIES ROAMING AIR MONITORING SYSTEM
This system was designed for indoor air monitoring with the needs of the Industrial Hygiene industry in mind. The system is capable of monitoring extremely low levels of gases in ambient air, at breathing levels.
Mobile Gas Cell
Open gas cell has an 80 meter optical path length for detection of extremely low-levels of gas species. Gas cell walls are completely removed for ambient air monitoring. A collapsable cover may be pulled up, enclosing the cell during purging for background measurements. System is integrated on a wheeled frame supporting a notebook data system and I2000 Series FTIR. Entire structure is rugged enough to withstand rigors of heavy use, and may be disassembled for maximum transportability.

Dimensions: 68" H x 12" W x 43" L

.5cm-1 FTIR MCT Detector, ZnSe Optics, I2001
The I Series FTIRs are designed for applications in extremely harsh sampling environments.  The I2000 Series features separate input 
output ports with collimated beams for external accessories mounted with axiot flanges.  The I2001 features include: 

  • The MIDAC ZnSe interferometer with selectable resolution from 0.5cm-1 to 32cm-1.  90o Michelson design, with patented, vibration resistant construction.  Beamsplitter is ZnSe (Zinc Selenide) with Ge coating for moisture protection.
  • Hermetically sealed, cast aluminum chassis.  19" x 12" footprint.
  • 50 lbs
  • MCT detector (1.8-15.5 micron range, 1mm x 1mm element size), 
  • Liquid Nitrogen cooled.
  • 1650 K IR source; silicon carbide glower
  • ZnSe (Zinc Selenide) windows for resistance to moisture damage.
  • All interface optics (gold coated for high throughput) AC and DC power adapters,  computer interface board, and cable.
AutoQuant Software Package for Windows 95, Version 3.0
Featuring automated data collection and real-time spectral analysis with optional alarm outputs which is implemented by means of an advanced multivariate algorithm developed by engineers at NASA Kennedy Space Center.  Spectra and quantitative results may be archived; and time of collection, concentration, and error analysis data may be later exported to any spreadsheet program, Excel, Lotus, etc. or used to generate concentration versus time plots for individual components.  The AutoQuant software package is based on a Visual Basic platform which incorporates C++ language DLLs for high speed execution of most arithmetic and collect  functions.  This approach gives MIDAC and MIDAC customers a great deal of flexibility in the development of custom features and routines for process, environmental, or QA/QC type applications.  Spectral files collected in AutoQuant are compatible with Galactics GRAMS and may also be converted to Galactics LabCalc format.

(Minimum hardware requirements: 586/75MHz processor, 32MB RAM, 4MB free hard drive space  although data collection can take hundreds of Megabyte space, and Windows 95)

Gas Phase Infrared Spectral Standards Library
Over 150 gas phase infrared spectra for quantification of sample spectra. To be used with AutoQuant, GRAMS, or LabCalc.

GRAMS/32tm with Data Acquisition 
GRAMS/32tm is a 32-bit Windowstm application featuring a graphical user interface and includes arithmetic and quantitative functions for Spectrometer control and data manipulation:

  • Basic FTIR data manipulation includes curve fitting, baseline correction, peak marking, subtraction, deconvolution, smoothing, quantification and many more FTIR functions. 
  • General Purpose Conversion Utilities. 
  • EZ Software with single button operation, simple screen layout and optional "instructor" mode is added at no charge enhance ease of use. 
Software requires Windows 3.1 or higher running in Enhanced mode (Windows NT does not work with Grams-32), a 386SX or higher computer (486 or higher recommended) with arithmetic coprocessor, at least 8MB of RAM (16MB recommended), and a mouse.
