IRT-1000 In-Compartment FTIR Microscope
The IRT-1000 is a compact and easy to use in-compartment FTIR microscope that can be used with any FT/IR-X Series instrument. The microscope is exchanged in the same way as an ATR or transmission holder in the sample compartment, without an requirement for adjustment or optical alignment. The excellent throughput allows for highly sensitive measurements for samples as small as 20 microns. The IRT-1000 can be operated from the integrated touch panel and a PC using Spectra Manager™ Suite. Sample is observation is made with an integrated color CCD camera and a 5 inch TFT color LCD monitor and recorded using the imaging function in Spectra Manager™. JASCO’s unique ATOS (Aperture Through Optical System) provides simultaneous viewing of the sample image and sampling location specified by an aperture.
System Features
- Easy location in the sample compartment – within seconds. No optical alignment is required before measurements
- Manual stage for moving and focusing the sample measurement area
- Three measurement modes: Transmittance, Reflectance, and ATR
- DLaTGS detector in FTIR main instrument (standard)
- MCT detector or NIR optimized detector (optional)
- Optional sampling accessories for liquid and powder samples
- Unique sample observation system allows observation of the sample, even during measurements
- Measurement and processing are performed by Spectra Manager™. A video capture of the sample view is stored in the spectral data file
Options for the IRT-1000
SmartPurge™
| An optional purge casing can be used to eliminate interference from atmospheric CO2 and water vapor bands. |  |
ATR Objectives
| There are three types of optional ATR objectives, select from:- ZnSe, Ge, or Diamond crystal prisms. An optional pressure sensor (recommended), can be used to protect the ATR objective prism. |  |
Liquid Sample Holder
| The liquid sample holder includes three standard spacers, 100, 50 and 25 um path lengths. |  |
Powder Sample Holder
| The powder sample holder can be used for diffuse reflectance measurements of samples mixed with KBr. Up to five samples can be loaded onto the holder. |  |
