本文提出了一种新的测定间三联苯和对三联苯的同步扫描－ＳＳ－ＲＴＰ法。固体基质选用慢速定量滤纸，重原子盐为Ｔｌ２ＳＯ４。以激发单色器和发射单色器的波长差△λ＝１８０ｎｍ进行同步扫描，其同步特征峰间三联苯为４５０ｎｍ，对三联苯为４９０ｎｍ（均指发射波长）。间三联苯可直接由该特征峰的高度进行定量测定。对三联苯在４９０ｎｍ处的特征峰略受间三联苯同步拖尾的影响，其峰值信号需加校正。间三联苯和对三联苯的线性范围分别为０．４６～９２ｎｇ／斑点和０．４６～４６ｎｇ／斑点
In this paper, we propose a new method for the simultaneous scanning of terphenyl and p-terphenyl with the method of SS-RTP. Solid matrix selection of slow quantitative filter paper, heavy atom salt Tl2SO4. To synchronize the wavelength difference Δλ = 180nm between the monochromator and the monochromator, the synchrotron characteristic peaks are 450nm for the terphenyl and 490nm for the terphenyl (both refer to the emission wavelength). M-terphenyl can be measured directly from the height of the characteristic peak. The characteristic peak of the terphenyl at 490 nm is slightly affected by the simultaneous trailing of the terphenyl. The peak signal needs to be corrected. The linear ranges of m-terphenyl and p-terphenyls were 0.46-92 ng / spot and 0.46-46 ng / spot
