  1. Innovations in FTIR and UV-Vis:New molecular spectroscopy solutions for your elemental analysis lab Agilent Technology and Science Symposium, Houston, June 27th 2013 Michelle Tomba Product Specialist Molecular Spectroscopy

  2. Outline • Innovation in FTIR – true innovation! • Cary 630 FTIR – maximum flexibility with innovative sampling • FTIR and portability – a reality! • Applications • The new UV-Vis way – be faster and more efficient! • Cary 60 with fiber optic probes

  3. FTIR Innovation Combines with Efficiency, Ease of Use and True Portability • Research • Routine • Analyzers • Portable • Hand Held Agilent Confidential

  5. 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, humidity • Liquid cells -> tedious, tricky handling • Difficult to run unstable samples Issues related to software • For spectroscopists– requirement for data manipulation

  6. Why most chemists used to avoid 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, humidity • Liquid cells -> tedious, tricky handling • Difficult to run unstable samples Issues related to software • For spectroscopists– requirement for data manipulation

  7. Cary 630 FTIR – Innovation on all aspectsSolving problems through innovation… DialPath TumblIR 630 Engine Transmission Diff/Spec Reflectance Di, Ge, ZnSe ATR Agilent Confidential

  8. Cary 630 FTIR – Anywhere and with ease of useSize, reliability, consistency and robustness • Toxic API (ex: anticancer drugs) • Air sensitive compounds • Explosive/Hazard risks

  9. Cary 630 with DialPath Sampling Technology As easy for liquid measurement as using ATR, and with the added benefit of variable and extended pathlength Oil/lubricants Environmental

  10. 250mL Fill Volume 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 pathlengths • Viscous 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 3mL Fill Volume

  11. Lab Interfaces on Portable FTIRs

  12. Why portable instruments (ex: FTIR)?Need an answer now and/or can’t bring the sample

  13. Handheld, Portable and Dedicated FTIRs Portable Handheld Dedicated Agilent Confidential

  14. 5500t with TumblIRsampling technology Biodiesel fuel contamination Biodiesel is deleterious to stored diesel fuel used for back up generator for nuclear fuel rods Biodiesel blending Turbine Oil - Mineral Oil Based Turbine Condition Monitoring GST Turbine Oil Condition Monitoring Hydraulic Fluid - Mineral Oil Based DTE Hydraulic Oil Hydraulic Fluid - Polyol ester Quintolube Oils, Lubricants and Biodiesel in Diesel Fuel • Hydraulic Fluid - Phosphate Ester • EHC Condition Monitoring • Gear Oil - Mineral Oil Based • Gear Oil condition monitoring • Oil Health • Level of antioxidant in turbine oil

  15. Handheld FTIR ApplicationsCoatings 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

  16. Handheld FTIR ApplicationsCoatings for Anodized and Coated Aluminium Acryl-cyanate based coating Silicone based coating Different levels of Al-oxide formation 2° alcohol plus alkyl based coating The spectra are distinct, and also vary directly with the thickness of the coating under examination.

  17. 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.

  18. UV-Vis Spectroscopy in the Laboratory • 8453 Key Features… • Photodiode array detector for complete spectrum capture • Fast full spectrum kinetics • Multi-component analysis • Small footprint – open sample compartment • Cary 60 Key Features… • Fiber optics for improved workflow • Analysis of small volumes • Xenon flash lamp for low ongoing costs of ownership • Photometric range (4.0 Abs with cuvette) for turbid solutions

  19. Cary 60 with Fiber opticFlexibility for increased throughput Chemical identification or study of chemical processes QA/QC on raw materials and finished product in manufacturing Wavelength Scans – What is it? Wavelength Scans – What is it? Fiber Optics Kinetics – what processes are occurring? Concentration – How much?

  20. Cary 60 - Fiber Optic Probes Replaceable Tips Various selection of pathlengths Cleanable and reusable. Microprobes Diameter: < 4 mm 10mm (2-5mm option) pathlength

  21. Cary 60 UV-Vis – Nano/Microvolumes • Accurate spectro measurements • Small volume measurements - Traycell • Save precious sample – measure 0.5 to 10 µL • Accurate and reproducible results • Excellent linear dynamic range • - Flexibility – no additional dedicated system required Abs 1 Abs mg/mL

  22. Cary 60 – Surface measurements • Non-destructive testing Requested by the Art Restoration Community Confidentiality Label • Remote (<1.5m from instrument) diffuse reflection measurements! • Fiber optic accessory with movable detector • 1.5 mm light patch – inbuilt CCD allows visualization of position • Needs fiber optic coupler (G6865A – for Cary 60) • Understand the sample surface porosity ie small beam
