Analyzing Samples

The 10 degree SRA slides in and out of the Cary 630 FTIR in seconds 
with no alignment required. See Page 24 for installation instructions.  
The 45 degree SRA easily slides into the transmission accessory. 
To install the 45 degree SRA into the Cary 630 FTIR: 
1  Undo the two screws holding the standard transmission holder 
and then replace the holder with the one provided with the 45 
degree SRA. Screw in the two screws to secure it to the 
transmission accessory. This modified holder has a shorter 
supporting arm on the front to allow greater access to the top of 
the accessory for larger samples. 
2  Slide the transmission accessory onto the Cary 630 FTIR. 
3  Slide the 45 degree SRA into the transmission accessory.

The Agilent MicroLab PC Software enables you to perform simple 
linear or Beer’s law calculations based on peak heights, areas, or 
ratios. Modeling via PLS programs is also available and can be easily 
integrated into the software. For information on how to do this, refer 
to the Agilent MicroLab PC Software User’s Guide.
