Drugs Separation Studies were performed for amphetamine, metham- phetamine, ketamine, heroin, and cocaine dissolved in methanol. Each target molecule appears at a speciﬁc Introduction compensation voltage under a ﬁxed value of radiofre- quency (RF) voltage. Values of compensation voltage With the increasing security precautions at the airports, of product ion peak at RF = 1480 V for cocaine, heroin, concert halls, or sport stadiums, detection of hidden ketamine, methamphetamine, and amphetamine at 110 C explosives and drugs becomes a challenging branch in appears at 3.33, 2.43, 2.12, -0.56, and -4.9 V, respec- analytical chemistry.
