摘　　要：传统油色谱在线监测装置需要定期到现场更换载气和进行校准,不仅运维工作量大,而且长期运行稳定性差。针对这种情况,研制出一种高精度免维护油色谱在线监测装置,使用空气发生器替代钢瓶载气实现载气免维护,高性能复合单色谱柱和定量进样提高了装置的检测性能,定期自校准保证了装置长期运行的可靠性和检测数据的准确性。Traditional oil chromatogram on-line monitoring device needs regular replacement of carrier gas and calibration,not only operational workload is big,but also the stability of long running is bad.In view of this kind of situation,this paper developed a high precision oil chromatogram on-line monitoring device without maintenance,through the use of air carrier gas generator replacement cylinders,carrier gas free maintenance was realized,high-performance composite single chromatographic column and quantitative sample improved the detection performance of the device,regular calibration ensured the device long running reliability and the accuracy of the testing data.
