Overview • Samples are collected with the sample traps and then vaporized by the desorber • The vaporized molecules then pass through the semipermeable membrane and into the detector • The molecules are ionized so that they can be mobilized through the detector by an electric field • The length of time it takes a substance to pass through the detector is known as its “time of flight” • Light ions travel faster than heavier ions

Overview Why Maintenance is Necessary • Optimize system performance • Keeps the sample and detector tubing clear of contamination • Prevents nuisance alarms • Minimize down time • Reduce maintenance and repair costs
