文摘

A thermal desorption modulation strategy for GC×GC experiments is proposed. Interface essentially comprises of two low-cost components commercially available. “Do-It-Yourself”, consumable-free modulator is simple to assemble and operate. Segmented configuration of modulation loop uses intermediate trap between stages. Cooling systems are bypassed using proposed interface allowing in-oven operation.
