Jilin University announced two major instrument purchase orders of 4.9 million yuan

on July 13, 2017, the Chinese government procurement announced two major instrument purchase orders of Jilin University, Including "enkuo Fourier transform attenuated total reflection infrared spectroscopy (Project No.: jdcg) and a new generation of large ultra-high voltage generation device accessories group (Project No.: jdcg) The bid winning amount reached 490903 yuan

it is understood that the two projects purchased by Jilin University this time include: a full vacuum Fourier transform infrared spectrometer, which is required to have attenuated total reflection measurement function, and can carry out in-situ reaction research of catalyst; 1 set of accessories for a new generation of large ultra-high pressure generating device, including 2 sets of pressure cones, 1 set of high-pressure molds, and 2 auxiliary clamps There is one set of major changes in the new national standard and one set of loading and unloading tooling. In addition, forgings are required to be free of wrinkles, burns, cracks, white spots, surface scabs and other defects

according to the bidding requirements, only manufacturers or dealers who are legally and financially independent, operate in accordance with relevant national laws and regulations, are qualified and able to provide soft non hydrophilic corneal contact lenses made of siloxane materials, which have high oxygen permeability, but do not have hydrophilicity, and are not comfortable to wear can participate in the negotiation. After winning the bid, the supplier must provide goods, spare parts and other materials on time according to the requirements of the negotiation documents and the contract, and be responsible for the packaging, transportation and insurance of the supplied goods and materials. From the time of arrival at the installation place designated by the user, the manufacturing and ex factory date of imported goods shall not be more than 12 months, and the manufacturing and ex factory date of domestic goods shall not be more than 6 months. If the time limit is exceeded, a special statement must be made in the remarks of the competitive negotiation response detailed quotation list

announcement of winning the bid for Fourier transform attenuated total reflection infrared spectrometer

infrared spectroscopy is an important means of analyzing the structure of compounds. The conventional transmission method uses tablet pressing or coating to measure, and it is difficult to test some special samples (such as samples that are difficult to dissolve, melt, crush, etc.). Fourier transform attenuated total reflection infrared spectrometer greatly simplifies the testing of some special samples, makes the analysis of micro components convenient and fast, and the detection sensitivity can reach the order of 10-9 g, which has become a powerful tool for material analysis. In a word, as one of the important experimental methods of infrared spectroscopy, ATR-FTIR overcomes the shortcomings of traditional transmission method, simplifies the process of sample preparation and processing, and greatly expands the application range of infrared spectroscopy. Now it has become a powerful tool and means to analyze the surface structure of substances, and has been widely used in many fields. This time, Jilin University has added these new instruments and equipment, and I believe that with the help of these instruments and equipment, it will help the school and teaching work better
