摘　　要：耶拿EA5000仪器元素分析仪是化验室常用的元素分析仪器,它可对硫、氯、氮等元素进行准确的分析。其检测级别为PPB级,对化工分析中的生产可以提供准确的数据依据。对仪器技术参数以及个别含量较大、黏度较大易挥发样品进样方法进行了优化,由原有的水平炉称量分析改为时间较短垂直炉方式进行分析,来延长仪器的使用寿命、减少仪器裂解管的更换频率、节省载气的用量和减少分析时长。优化后节约了分析成本,提高了分析效率。Jena EA5000 instrument elemental analysis instrument is a commonly used elemental analysis instrument in laboratories,which can accurately analyze elements such as sulfur,chlorine and nitrogen.The detection level is PPB level,so the production in chemical analysis can improve the accurate data basis.Therefore,maintaining the instrument is also the top priority of the work.So I changed the technical parameters of the instrument to prolong the service life of the instrument,reduce the replacement frequency of the cracking tube of the instrument,save the amount of carrier gas,and save the cost of analysis.For individual samples with large content and high viscosity and volatile samples,the original horizontal furnace weighing analysis was changed to a shorter vertical path for analysis.In view of the above,it is also extremely important to maintain the instrument.Therefore,in order to carry out the assay and analysis more efficiently,the technical parameters of the instrument were optimized based on the concept of increasing efficiency.
