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 collapsible 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. 90° 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 Windows 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.
