IR Spectroscopy

If you’re looking to prepare your liquid, mull or capillary sample for FTIR analysis look no further! Firebird Optics has you covered with various demountable/sandwich cell configurations along with permanently sealed options.

For powder samples, a common way to do things is with the KBr pellet method. Samples are crushed into a powder with a laboratory-grade mortar and pestle and mixed with KBr powder and then installed into a pellet-forming die. Once pellets are ready they can be inserted into a pellet holder, which snaps into a standard FTIR spectrophotometer holder.

Short pathlength cells are useful for measuring higher concentration gas samples. Firebird Optics gas cells can be used on samples with concentrations of 100ppm and above. These cells are airtight and made for extreme pressure applications in excess of 1 x 10-8 Torr.

Attenuated Total Refection (ATR) prisms operate by measuring the changes that occur in a totally reflected infrared beam when the beam comes in contact with a sample. ATR is the best choice for solids, gels, pastes and liquid samples.
