Are there any commonly used analytical instruments in chemical analysis?
Infrared spectrum, ultraviolet spectrum, mass spectrum, nuclear magnetic resonance and gel chromatography
1. application of new technologyThe current widespread use of EDA (Electronic Design Automation), CAM (Computer Aided Manufacturing), CAT (computer aided test), DSP (digital signal processing), ASIC (ASIC) and SMT (surface mount technology) etc..2. changes in product mixPay attention to performance price ratio. While paying attention to the development of high-end instruments, we pay attention to the development and production of high and new technology and large quantities of products.Focus on system integration, not only focus on stand-alone, more attention to systems, product softening, with all kinds of equipment loaded with CPU, after the realization of the digitization, the software invested a huge amount of manpower and financial resources. The instrument into a simple formula: =AD/DACPU instrument software, AD chip analog signals into digital signals, and then processed by a software transformation with DA output.3., the product development standards have changedFrom "technology driven" to "market driven", from "pursuit of sophisticated" to "just right"". The development of a successful product criterion is that the user has a clear demand; can use the shortest time to market development; the function and performance to be just perfect; another change of product development standards is the direction of contraction, the advantages of centralized.4., production technology, specializing in production, do not engage in large and completeAutomatic test system is adopted in production process. At present, the automatic test system is set up with GP-IB instrument. The production line is full of large test cabinets, which can automatically test, count, analyze and print the results.
Scientific discoveries are often made by the invention of new observation methods. Taking physics Nobel prize winners for example, fifty percent of the work was created by the creation of new instruments or testing methods. Acquisition, conversion, storage, processing and reveal the material motion instrument is essential tool to realize the information, instrumentation equipment level reflects the productivity of a country's development and modernization level to a great extent.
