Frequently Asked Questions (FAQ's)
Many questions can be answered from our technical specification data sheet. We’ve also listed a few frequently asked questions with their answers.
Q1: What makes your spectrometer different?
Unlike conventional FTIR spectrometers, the rugged IRmadillo™ FTIR spectrometer doesn’t use a moving-mirror to form the interferogram. Our solid-state interferometer is immune to vibration, and can survive in harsh production environments without having to rely on fragile fibre connections, or complicated protective mountings.
Q2: Can your FTIR spectrometer analyse minerals, metals (solid), powders or gases?
At this time, our ATR probe sample interface is best suited for analysis of liquids or slurries. It is most effective when used in material identification and chemical reaction monitoring of fluids in manufacturing environments — such as chemicals, pharmaceuticals, bio-based renewables (bio-fuels and fermentation products), petro-chemicals, and food and beverages – all in liquid form.
For the future, there are plans to consider sample interfaces for solids and gases. Please contact us to discuss further.
Q3: We are looking for a portable, hand-held device. Can your instrument be used in the field?
The Keit instrument is relatively compact and portable. However, the instrument weighs nearly 17 kg (over 36 lb) and therefore is not a hand-held device. That said, our instrument is extremely rugged and is meant to be used in rough environments (including outdoors). We are exploring hand-held designs for the future, so please contact us to discuss.
Q6: How does it work? How can it function without fibre-optic cables?
Keit has replaced all moving parts with fixed mirrors and beam splitter. Read our FTIR Spectroscopy section for specific details. No moving parts and an exceptionally tough structural design mean that the Keit instrument can perform despite the most challenging operating environments. It can be mounted directly onto manufacturing vessels, therefore there are no fibre optic cables as the fixed dip probe on the IRmadillo spectrometer is inserted directly into the vessel or the in-line production system.
Q7: What about data export? Is it compatible with standard systems?
The IRmadillo™ FTIR spectrometer is compatible with all major analysis packages. It exports data in standard CSV text files or can connect to your plant data network and communicates via OPC server directly with your control system. All data analysis happens within the device, no additional PC is required. It also supports all major communication protocols.
Q8: What is your price and can I buy one now?
Please contact us at firstname.lastname@example.org for further information.
Q9: Do you integrate with my plant control system, or my chemometrics package?
The spectra that the Keit instrument outputs are compatible with software packages from the major vendors. The Keit rugged FTIR spectrometer communicates via an OPC server for direct data connection to your plant control or information management system.
Q10: What is the service and maintenance process?
Due to the lack of moving parts, there are no component wear issues or significant recalibration requirements. However, to ensure continued high performance we recommend an annual preventative maintenance check which will be performed by a Keit Engineer.
Q11: What’s the meaning behind the name IRmadillo?
The product name combines the abbreviation for Infra-red ‘IR’ and the word ‘Armadillo’; a combination that describes the function AND functionality of Keit’s FTIR spectrometer. Armadillos are tough, armour-plated animals that live in a harsh climate. Keit’s rugged, mid-infrared instrument is also compact, tough, and built to function under challenging conditions. Perfect match!
Q12: Is your instrument certified for explosive (Ex) environments?
The Keit IRmadillo™ FTIR spectrometer is certified ATEX and IECEx for use in hazardous and potentially explosive environments.
