Perkin Elmer FTIR-Spektrometer 1725 X

The Perkin-Elmer Model 1725X is a new benchtop FT-IR spectrometer controlled by an IBM® PC-AT, PS/2 or compatible computer. Equally at home in a routine analytical or research environment, the Model 1725X has optical and data handling facilities to match the most demanding applications. Stability and sen­sitivity levels are second to none, providing the most reliable results in the shortest time. In common with the other members of the 1700X Series, the optical unit is sealed and desiccated, removing the need to purge for most applications. Sample turnaround time is typically seconds rather than minutes.

The Infrared Data Manager and Instrument Control software packages use a mouse driven window envi­ronment to provide logical and user friendly inter­action. Spectral SEARCH, quantitative analysis and macro-programming packages are also available. Data import and export facilities are provided using industry standards such as JCAMP-DX and Lotus® 1-2-3. These provide a gateway to a host of third-party software packages and network systems and ensure that the Model 1725X can be fully integrated into the computer controlled laboratory.

FEATURES

n          Research level performance

Range, resolution and sensitivity levels normally associated with research spectrometers allow the Model 1725X to handle the most demanding applications.

n          The PC advantage

PC control and data compatibility provide a link with the expanding world of industry standard hardware and software.

n          Friendly, versatile software

A mouse-driven window software environment is ideal for both routine and research users.

n          FuIIy upgradeable

The Model 1725X is compatible with every accessory and upgrade expected of a research level FT-IR spectrometer, including IR micros­copy, GC-IR and external beam facilities.
