Type "C" Cavity
Cell and Wedge-Cavity
Cell in an Infrared
Spectrometer.
"WHY WEREN'T THEY THOUGHT OF SOONER?" So say those who have used the new cavity infrared absorption cells recently introduced by Connecticut Instrument Corporation. The Cavity Cell pictured above in the sample beam is fashioned from a single block of crystal — as a result it is tight, has a low volume (down to one microliter) in the micro models, has no metal in contact with the sample, is readily cleaned and buffed and, believe it or not, costs no more than a single window for a conventional absorption cell. In the reference beam is the unique new Wedge-Cavity Cell that eliminates the need for matched cells. This cell is a really practical variable Ijid space cell that is as versatile as it is inWÊ^g^-'·-^ . expensive. Its single crystal construcW^ """"' _„*.«·»· tion simplifies cleaning—the WedgeCell may even be used for sampling. Both cells are ideal for the new low cost spectrometers, like the Infracord and the IR-5. Cavity cells are available in all infrared transmitting materials.
