FTIR instruments have distinct advantages over dispersive spectrometers: 1. Better speed and sensitivity. 2. Internal laser reference. The use of a helium neon laser as the internal reference in many FTIR systems provides an automatic calibration. 3. Increased optical throughput. 4. Simpler mechanical design. 5. Elimination of stray light and emission contributions.
I always use 400 - 4000cm-1.
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Yes, polystyrene beads are safe to use. One can learn more about polystyrene beads at popular on the web sources such as Tempo Foam, eHow, and Wise Geek.
The best method to use for TV calibration appears to be professional calibration. Either a pro, who has been recommended by a specialty retailer, or an independent contractor certified through the Imaging Science Foundation.

The mixture of Polystyrene and Acetone results in the creation of a sticky residue as the Polystyrene beads dissolve into the Acetone. You can use Nail polish remover with Acetone. However, the chemical reaction occurs at a much more rapid pace with pure Acetone.
Only use calibration control in unloaded condition of the torque transducer. Cal control output is approximately equal to transducer full scale output. Exact value is noted on calibration certificate.
A 'snug fit' polystyrene holder.
Polystyrene plastic is the main component of millions of plastic. There are a number of polystyrene glues available in model and hobby stores. Almost all are a form of Butanone. I prefer to use MEK for my models. Mek is a form of industrial butanone. Super glues can also be used in polystyrene plastic.
