LIQ HPLC purity analysis method

The brighter the color, the more LIQ, the whiteness is quinoline.

Use sublimation based on yield

Elemental analysis and HPLC detection of 8-hydroxyquinoline

This can be added in general water-soluble compounds (refer to the phenol) analysis method

may add a little quaternary ammonium salt regulation

LIQ cannot use liquid phase detection content. At present, generally is to measure DS and TGA, there is a range, as long as it is within the scope
If you want to know how the quality is, it is determined by sublimation, ash, floc how much judgmentand many more...
Does the landlord do OLED terminal materials?

I beg you to give LiQ HPLC method

I want to ask the landlord, do you know if you know the HPLC detection method of LIQ, ask for enlightenment
