  • Page 7: Introduction

    The IRmadillo has no moving parts and a rigid probe which is inserted directly into the reaction vessel or process pipeline for continuous real-time analysis. The device is tolerant of extreme vibration levels.

  • Page 8: How Ftir Spectrometers Work

    What makes the IRmadillo different? The IRmadillo is an FTIR instrument in that it creates an interferogram and requires a Fourier transform to interpret the information for a spectrum. But rather than using a moving mirror to create the interferogram it uses a proprietary arrangement of fixed mirrors to create an interference pattern.

  • Page 27: Using The System And Software

    This manual describes the Keit Spectrometer Software (Keit Spec) version 4.0.7. Getting started Keit Spec uses the concept of projects to store spectral data. Two types of project are available: (1) Manual Sample Acquisition and (2) Continuous Collection. 5.2.1 Manual sample acquisition This is an operation mode that allows you to collect individual samples, either for bench analysis or as part of chemometric model-building.
  • Page 28 Click on the Background Scan button and choose Collect Background. Because all subsequent scans will use the background scan to calculate the absorbance, it is very important to scan for as long as possible to optimise performance. The IRmadillo NOTE does not need frequent new background scans to be collected, so it is worth investing time in a high-quality background scan at the beginning of use.

  • Page 29: Manual Sample Acquisition

    You can now remove the probe from the sample, thoroughly clean the probe and ATR element, then insert the probe into the next sample and start the next collection. www.keit.co.uk Using the system and software: DOC0535 (10 July 2019, 16:56) Back to Table of Contents...

  • Page 30: Monitoring A Reaction Or Process

    The IRmadillo is designed for reaction and process monitoring. The Keit Spectrometer Software (Keit Spec) saves data directly to a database as spectra are generated. This means you can perform some interpretation during use with a chemometric model generated with various external packages, as well as exporting the data into text files for further analysis.
