Data Sheet
FTIR spectrochemical ATR imaging need no longer be limited to the
microscopic level. Combined with the Large Sampling (LS) accessory and
the Imaging Golden Gate Diamond ATR accessory, ATR images can now
be collected as easily as any ordinary spectrum, over much larger fields
of view, allowing for chemical heterogeneity to be probed where
previously not possible.
Taking full advantage of Agilent‟s FTIR ATR imaging technology, the
Imaging Golden Gate Diamond ATR accessory offers the highest quality
chemical images that are distortion and aberration-free with a preserved
aspect ratio. All this, while maintaining the Golden Gate‟s robustness
and ease-of-use that are so familiar to FTIR experts the world over.

With the Imaging Golden Gate Diamond ATR
Accessory, you can:
Maximize Productivity. Traditional FTIR imaging
usually requires some degree of sample
preparation, often needing cross sectioning using a
microtome before delicately placing a sample on an
infrared transparent substrate for transmission
mode imaging. Using the Imaging Golden Gate
accessory, little or no sample preparation is
required. Simply clamp your sample in place and
obtain full 2D chemical infrared images in seconds.
Preserve Precious Samples. Most samples can be
analyzed „as is‟, without destruction, allowing for
the same sample to be used elsewhere or further
analyzed using other techniques. Valuable or rare
samples need not be destroyed through the sample
preparation required for other spectroscopy
techniques.
Analyze Challenging Samples With Ease. With the
renowned robustness of the Imaging Golden Gate
Diamond ATR accessory, samples previously
considered impossible to measure can now be
analyzed with ease. You can measure paper,
powders, polymer pellets or even rocks. The
possibilities are endless!
Perform Hot, Cold, and In-Situ Experiments. A
variety of top plate options are available making it
possible to perform chemical imaging experiments
from 200 °C down to near liquid nitrogen
temperatures. Study melting, crystallization and
curing, or dissolution behavior as a function of time
for pharmaceutical based applications — the result
is outstanding versatility!
Heterogeneous liquids
Coated wires
Figure 1 demonstrates how simply placing a multicomponent polymer on the surface of the diamond ATR
crystal can produce an image in seconds, highlighting
the various chemical domains in this heterogeneous
sample. This particular sample was too thick to
measure using traditional transmission methods.
Therefore, ATR imaging was used. A visual inspection
suggested that this polymer consisted of only two
components. However, as can be seen in Figure 1, three
distinctly different polymer layers were identified.

polymer; (a) Hydrocarbon resin (1450 cm-1), (b) Polyester (1750 cm-1) and (c)
Polyamide (1650 cm-1and 1540 cm
