托吡酯是一种抗癫痫药物。根据美国药典（USP）33版-国家药品标准（NF）28版补充1，托吡酯片需要进行杂质测试。在“特定测试”部分提到了硫酸盐和硫胺酸盐的测定。等度方法主要适用于非抑制型离子色谱（IC），但由于硫胺酸盐在这些条件下会显示负峰，因此使用抑制技术是有利的。
Topiramate is an antiepilepsy drug. According to USP Topiramate tablets have to be tested for impurities. The determination of sulfate and sulfamate is mentioned under 'Specific Tests'. The isocratic method applies a column eluent combination primarily used for non-suppressed IC. But as sulfamate shows a negative peak under theses conditions the use of suppression is advantageous.
