Did You Know...

Some ATR crystals can  

be easily damaged.  

However, in selected cases, the crystal can  

be re-conditioned at

a fraction of the cost  

of a new plate.

Dear Friend, 

 

The spring trade show season is finally over. Thanks to all who stopped at our booths at Pittcon, ACS and Analytica (the next opportunity would be ACS in Philadephia, JAIMA and possibly Analytica China). Looks like there are significant shifts in the trade show and spectroscopy instrumentation areas, as both seem to be shrinking in size :)

 

We also have noticed increased interest in gas analysis, and what a coincidence - new PIKE long path gas cells are an excellent answer to this trend (please see a quick movie posted below related to this subject). We will keep our eyes open on the small FTIR instruments. There are multiple applications and specialized accessory opportunities in this area - so please keep us in mind if any special needs arise. We are just one click away: [email protected] 

 

Warm Regards,

PIKE Team

The Unusual Little Gas Cell  

Not all gases are clean and some may muck-up and contaminate gas cell optics and its body pretty quickly.  Obviously, results obtained with a "dirty" cell will not be reliable, and cleaning and re-alignment of a typical gas cell could be a total pain in the neck. So why not make a gas cell that can be disassembled by hand, with pre-aligned optics and easy to clean?   Well guess what...

 

ATR or Grazing Angle Specular Reflectance for Analysis of Monolayers and Thin Films?   
 
Both techniques

can be used for this unique application. However, ATR offers a significant sensitivity advantage. With a 60� Ge ATR crystal and p-polarized light, the IR beam refracts into the thin film and then is reflected off the gold (or silicon) substrate surface. The reflection is returned again by the Ge crystal surface, and the process repeats itself multiple times.  

 

In result, we observe numerous reflections throughout the sample layer, despite the accessory being configured as a single reflection ATR -  hence enhanced sensitivity. Thanks to this multiple reflection phenomenon, the measurement can be run on an FTIR spectrometer equipped with a standard DTGS detector. VeeMAX II, PIKE's variable angle ATR/specular reflectance accessory, and a polarizer are required for this experiment. Visit the Specialized Applications section on our website for several Application Notes.
