The current practice of comprehensive two-dimensional gas chromatography is dominated by systems using thermal modulators based on the slotted heater or longitudinally modulated cryogenic trap. The cryo-jet modulator is an attempt to design a stationary-thermal modulator [226]. The cryo-jet modulator consists of two fixed-position nozzles positioned close to each other. These nozzles spray alternating pulses... [Pg.222]
