The KHK720R is a new generation thermal desorptionsystem that integrates an automatic sample injection systemand a thermal desorption device. lt serves as a samplepretreatment system compatible with various brands of gaschromatography (GC) for the analysis of volatile organiccompounds (VOCs). The ZHK3601 is equipped with anautomatic sampler capable of handling up to 72 adsorbenttube samples, signifcantly enhancing the instrument'sanalytical capacity and processing effciency. The fullyupgraded control system makes operation simpler andmore intuitive. it can also be used in conjunction with thegas bag automatic sampler for the pretreatment of gas bagsamples (Tedlar bags)
