(UPS). Contact support@keit.co.uk for further information. If you are unable to use a UPS, you may find that the system fails to start correctly following a power cut. In this situation, Keit recommends power cycling first the IRmadillo and then the controller. -
Page 7: Purging The Irmadillo
The IRmadillo is fitted with a single body purge inlet and a breather in the probe. The Inlet is shipped with a blanking plug that needs to be removed before use. DOC0945 (11 August 2022 10:01) www.keit.co.uk Back to Table of Contents... -
Page 8: How To Connect Data Communications
The ideal purge gas is dry nitrogen. Alternatively, dry air from a purge gas generator can be used. The output from this purge gas generator should have a minimum quality according to ISO8573-1:2010 of Class 1:2:1 (dust:water:oil) or better. Keit can recommend suitable generators that achieve this outlet air quality; contact support@keit.co.uk. Purge gas generators may include an internal compressor or use factory-supplied compressed air with a minimum quality of Class 4:4:4 (dust:water:oil). -

Page 10: Checking For Warnings And Checking The Probe Is Clean
Once exposed to a suitable solvent, wipe the ATR with a clean cloth. The metal tube of the probe can also be cleaned by wiping with a cloth. For hard-to-remove fouling (such as biofilms or dried-on chemicals) Keit recommends an oxidative acid clean. First, clean the ATR using the methods outlined above, then perform the following: ... -
Page 11: Recognising If The Probe Is Clean
Figure 8: Sharp spikes within the region indicating an unclean probe A peak at 1400 cm indicates that there is some water on the probe. This could indicate poor purge quality. DOC0945 (11 August 2022 10:01) www.keit.co.uk Back to Table of Contents... -
Page 12: Taking A Background
Probe installation is unique for each application. Safe installation of the probe into the process is the responsibility of the user and should be assessed by a suitably trained person. DOC0945 (11 August 2022 10:01) www.keit.co.uk Back to Table of Contents... - Page 13 The IRmadillo needs to be suitably supported. The weight of the instrument is ~18 kg, and it must be supported using the mounting points at the base, either through a custom stand or using a Keit Cradle. The probe should not be used to support the instrument.

800-1800 cm (contrast with Figure 7, above). If evidence of emitter ageing is seen, it may be required to take a new background scan to remove this effect – contact Keit for advice. DOC0945 (11 August 2022 10:01) www.keit.co.uk... -
Page 16: Remote Health Check
Page 15 3.4. Remote health check Keit can perform an annual examination of your system’s health data remotely to determine if any servicing needs to be carried out. This includes review of internal diagnostics for warnings and errors, component performance for signs of premature ageing, and evaluation of background reference spectra history for signs of operator error or progressive damage. - Page 17 Figure 17: Using the fibre-cleaning pen to the Souriau plug Once both halves of the connector have been cleaned then they can be reconnected.

The sample cell may be cleaned using standard laboratory cleaning practices, as appropriate for your reaction. Also ensure the ATR element has been thoroughly cleaned and dried before use of the sample cell. DOC0945 (11 August 2022 10:01) www.keit.co.uk Back to Table of Contents... -
Page 23: Flow Cell
The flow cell assembly contains a pressure vessel and has been designed to withstand the analyte conditions that are specified on your product label. For detailed technical drawings, contact Keit. 5.2.1. High flow cell - ASM1396 The high flow cell is a ~27ml vessel that can be secured to the end of the probe for continuous analysis of your process. -

The flow cell has restricted passages so liquids with suspended CAUTION particles may cause blockages. Excessive flow rates may cause cavitation and erosion; consult with Keit if in doubt. Ensure that the NPT fittings are attached prior to final assembly; CAUTION this avoids any side loads on the IRmadillo spectrometer which may cause damage. -
Page 27: Flanged Probe
The flange and hub form a seal with the process pipework and as such are safety critical to prevent an accidental discharge of the process media. Keit recommends regular inspection of the WARNING integrity of the welds on the front and rear in line with local safety procedures. -
Page 28: Installation
The probe body and hub are manufactured from Hastelloy as standard, which is resistant to many aggressive chemicals. However, you are advised to check with Keit before installing on a new process. Before beginning installation, ensure that the gasket is in good condition and that the sealing faces are not scratched or dented. -
