Page 3: Purging The Irmadillona
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 4: Avoiding Fouling
Even a thin layer of scaling or fouling will prevent the IRmadilloNA from being able to ‘see’ the process fluid. To minimise the risk of fouling of the diamond window, we recommend taking the following steps during installation: DOC1049R (22 February 2024 12:07) www.keit.co.uk Back to Table of Contents... - Page 5 Depending on your process chemistry, this may be achieved by choosing a high temperature location and using heat tracing and insulation to avoid localised cooling. Higher process temperatures often maximise the solubility of potential fouling substances. DOC1049R (22 February 2024 12:07) www.keit.co.uk Back to Table of Contents...

Page 6: 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: Souriau in-line plug •... -
Page 7: Recognising If The Probe Is Clean
Several sharp peaks in the region 800-1800 cm indicate that the probe has not been cleaned properly. Figure 4: Sharp spikes within the region indicating an unclean probe DOC1049R (22 February 2024 12:07) www.keit.co.uk Back to Table of Contents... -
Page 8: Taking A Background
This must be performed before the probe is inserted into the reaction/process of interest. The process for collecting a reference scan can be found in DOC0893 KeitSpec Software User Manual, Section 1, Getting Started. DOC1049R (22 February 2024 12:07) www.keit.co.uk Back to Table of Contents... -

This may cause chemometric models to give incorrect results unless the model uses an appropriate pre-treatment to remove the effect. Any model built by Keit will have this taken into account. DOC1049R (22 February 2024 12:07) www.keit.co.uk... -

– contact Keit for advice. 2.2. 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. -

O-rings annually. Also inspect the clamp and C-pieces for any signs of degradation, cracks, or damage. If the clamp and/or the C-pieces shows signs of significant wear, do not re-fit them and contact support@keit.co.uk for advice. 4.1.2. Cleaning The sample cell may be cleaned using standard laboratory cleaning practices, as appropriate for your reaction. -

4.3.2. Installation Assemble the inclined stand to the desired height; two positions are possible. For technical drawings, contact Keit at support@keit.co.uk. To install the inclined stand to the instrument, carefully roll the spectrometer over such that the mounting holes are pointed upward, the instrument should be disconnected from power coms and purge to avoid damage to the cables or twisting.
