The suitability of Hitachi 911 ion-selective electrodes to analyse neat sweat samples for sodium and chloride was investigated. Sweat samples obtained using the Gibson and Cooke method were analysed by flame photometry for sodium and coulometry for chloride. Specimens obtained by the Wescor Macroduct collection procedure were analysed by ion-specific electrodes. No significant differences between sodium and chloride results were found between the two different collection methods and analysis procedures. Analysis of neat sweat can reduce errors in sweat analysis by eliminating extraction and dilution stages. Errors could occur with use of a serum compensator in the calibration of ion-selective electrodes.
研究了日立911离子选择电极用于分析纯汗液样本中钠和氯的适用性。使用吉布森和库克方法获得的汗液样本通过火焰光度法分析钠含量，通过库仑法分析氯含量。通过韦斯科宏导管收集程序获得的样本通过离子特异性电极进行分析。在两种不同的收集方法和分析程序之间，未发现钠和氯的检测结果存在显著差异。分析纯汗液可通过消除提取和稀释阶段来减少汗液分析中的误差。在离子选择电极校准中使用血清补偿器可能会产生误差。
