How it works
The Perkin Elmer 983 operates as a double-beam spectrophotometer using a beam-splitting chopper (BSC) and a pre-sample chopper (PSC). The BSC operates at 30 Hz and the PSC at 10 Hz. The instrument uses a thermocouple detector with a high-gain amplifier; the detector response time constant is 12 milliseconds. Because the detector output never reaches the true level before the choppers switch, the %T scale must be calibrated. The monochromator employs a four-grating turret and nine filters, with a slit mechanism driven by a motor and cam in the original design. The light source is a Globar.[3][2]
