A bitterant (or bittering agent) is a chemical that is added to a product to make it smell or taste bitter. Bitterants are commonly used as aversive agents to discourage the inhalation or ingestion of toxic substances.

Isotope capsule for well logging

The invention discloses an isotope capsule for well logging. The isotope capsule comprises a capsule body, an isotope solid tracer, a capsule cover and an additive; the capsule body and the capsule cover are connected to form a capsule; the isotope solid tracer and the additive are both located in a cavity in the capsule; and the additive comprises a bitter agent and an odor agent. Isotope solid tracer powder is fixedly arranged in a closed space by adopting a capsule shell, so that the controllability of an isotope is improved, the pollution channel is controlled from the source of the isotope, and secondary pollution does not exist in the whole process of delivery, transportation, split charging and use; the dosage of the isotope solid tracer in the capsule shell is determined accordingto the minimum dosage of production well injection profile logging, after capsule isotope manufacturing is completed, the secondary split charging link is avoided in the distributing and assembling process, the timeliness of the assembling and using link is improved, an operator can carry out on-site reassembling after the isotope attenuation phenomenon occurs, and the production efficiency is improved, and operation is safer, more efficient, simpler and more convenient, and personal injuries are avoided.

A method for detecting denatonium benzoate content in toy materials

The invention discloses a method for detecting the content of denatonium benzoate in toy materials, which comprises preparing standard stock solutions, intermediate working standard solutions and serial concentration standard solutions respectively, preprocessing samples to be tested, and performing high performance liquid chromatography detection , using acetonitrile-water (30:70, v / v) solution as the extraction solvent, after ultrasonic extraction, constant volume, after filtration, gradient elution is carried out with acetonitrile-water as the mobile phase, and a C-18 column is used as the chromatographic column, With a photodiode array detector, the detection wavelength of denatonium benzoate is 227.4nm, the detection limit is 2.66ng (based on 3 times the signal-to-noise ratio), the average recovery rate is 99.3%, and the method precision is 0.81%-2.36%. This method has low detection limit and high precision, and is suitable for the determination of the bittering agent denatonium benzoate content in this field. It can improve the level of management of liquid or viscous toys in my country, protect the legitimate rights and interests of children and consumers in China, and at the same time promote the development of toys in my country. The smooth export of products is of great significance.
