Why most chemists are avoiding FTIRIssues 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

Cary 630 FTIR – Anywhere and with ease of useSize, 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 pathlength

Oil/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 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 250mL Fill Volume

Oils, Lubricants and Biodiesel in Diesel Fuel5500t 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

• Hydraulic Fluid - Phosphate Ester– EHC Condition Monitoring

• Gear Oil - Mineral Oil Based– Gear Oil condition monitoring

• Oil Health– Level of antioxidant in turbine oil

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

The spectra are distinct, and also vary directly with the thickness of the coating under examination.

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.
