Popis:	A thermal modulator is a chemical instrument component that controls the temperature of a short length of gas chromatographic column as a function of time and position. Simple rotation of a heater element over a capillary gas chromatography column accumulates sample substances, focuses them into a sharp concentration pulse, and accelerates the concentration pulse onto a following column or to a detector. The series of concentration pulses formed by continuous operation of a thermal modulator is a modulation signal that is potentially useful in the design of high-speed, portable instrumentation. © 1996 John Wiley & Sons, Inc.
