ROHS2.0 Tester Video

~When using liquid chromatography to detect samples, it is required that the method used can separate all the components to be tested, and the separation degree should be greater than 1.5. When the separation degree is lower than 1.5, it will cause significant detection errors when detecting samples. From the spectrum on the previous page, it can be seen that our scheme can achieve the separation of four substances, all of which are above 1.8. I have learned about the testing plans of other companies, which basically combine DBP and DIBP for testing (that is, these two substances * overlap together), and can only detect the total amount of these two substances, not the individual content. Some companies have adopted modified methods, where DIBP and DBP can be partially separated, but they are also strict
Overlap again. The test spectrum provided by Junhuiteng Company is shown in the figure on the right,
DIBP and DBP overlap severely and have significant baseline fluctuations. ~Detection spectra of four ortho benzenes in RoHS 2.0
