Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with specific examples. Unless otherwise specified, the reagents and equipment used in the present invention are conventional commercially available reagents and conventional equipment in the art.
[0030] Embodiments of the present invention provide a method for detecting metal elements in liquid crystal materials, comprising the following steps:
[0031] Step S1, sample sampling: After splitting the thin film transistor liquid crystal display panel, use a plastic scraper to scrape the liquid crystals on the TFT substrate side and the CF substrate side respectively, collect them into sample bottles, and accurately weigh them with a balance to obtain test samples;
[0032] Step S2, sample pretreatment: using solvent dilution method, using iso-propylalcohol (IPA) as liquid crystal dilution solvent, diluting the detection sample obtained in step S1 by 8 to 12 times (preferably 10 times) to obtai...
