Innovations in FTIR and UV-Vis: New molecular spectroscopy solutions for your elemental analysis lab Agilent Technology and Science Symposium, Houston, June 27th 2013Michelle Tomba Product SpecialistMolecular Spectroscopy
Outline Innovation in FTIR – true innovation!Cary 630 FTIR – maximum flexibility with innovative sampling FTIR and portability – a reality!ApplicationsThe new UV-Vis way – be faster and more efficient!Cary 60 with fiber optic probes
FTIR Innovation Combines with Efficiency, Ease of Use and True Portability Hand Held Portable Analyzers Agilent Confidential Routine Research
WHY FTIR? 70 um 70 um Chemical Image Image @ 3295 cm-1 - Nylon 3500 3000 2500 2000 1500 1000 0.2 0.1 0.0 Wavenumber Absorbance Image @ 1285 cm-1, poly phthalate, ~4 microns
Why most chemists are avoiding FTIR Issues related to instrumentation Not stable (vibration, conditioning, humidity…)Alignment of optics Requirement for purge gas Bulky Long acquisition time (minutes) Issues related to sample preparation KBr pellets, NaCl plates -> long, costly, non-reproducible, humidityLiquid cells -> tedious, tricky handling Difficult to run unstable samples Issues related to software For spectroscopists – requirement for data manipulation

Cary 630 FTIR – Innovation on all aspects Solving problems through innovation… 630 Engine DialPath TumblIR Di, Ge , ZnSe ATR Diff/Spec Reflectance Transmission Agilent Confidential
Cary 630 FTIR – Anywhere and with ease of use Size, reliability, consistency and robustness Toxic API (ex: anticancer drugs) Air sensitive compounds Explosive/Hazard risks
Cary 630 with DialPath Sampling TechnologyAs easy for liquid measurement as using ATR, and with the added benefit of variable and extended pathlengthOil/lubricants Environmental
DialPath Changes How Liquids are Analyzed by FTIR Qualitative (raw material ID) and quantitative (impurity levels determination) analysis on a SINGLE accessory – no need for disassembling of traditional liquid transmission cell to change pathlengthsViscous liquids analyzed without blockage and leakage issues typically associated with traditional variable transmission cells Handles viscous liquids and volatile solvents equally well As easy to use as ATR, but more sensitive with 30-1000 micron pathlengths available 250 m L Fill Volume 3 m L Fill Volume
Lab Interfaces on Portable FTIRs
Why portable instruments (ex: FTIR)? Need an answer now and/or can’t bring the sample

Handheld FTIR Applications Coatings for Anodized and Coated Aluminium Highly polished, anodized then subsequently coated (with a variety of coatings) aluminium high reflectivity reflectors. Samples ran with the 45° Spectral Reflectance interface for a 4100 ExoScan FTIR. Spectra on next slide
The spectra are distinct, and also vary directly with the thickness of the coating under examination. Silicone based coating Acryl-cyanate based coating 2° alcohol plus alkyl based coating Different levels of Al-oxide formation Handheld FTIR Applications Coatings for Anodized and Coated Aluminium
Intuitive: Routine FTIR must have flexible, simple to use (intuitive) software Software guides the user through the selected method. Also recognizes the correct sampling interface to guide proper sampling techniques and cleaning.
