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

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 Technology
As easy for liquid measurement as using ATR,
and with the added benefit of variable and
extended pathlength

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
3mL Fill Volume
• As easy to use as ATR, but more sensitive
with 30-1000 micron pathlengths available
250mL 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.

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

Cary 60 – Surface measurements
Non-destructive testing
Requested by the Art Restoration Community
• 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
