Analytical instrument purchase should pay attention to what aspects
The choice of analytical instrument is very important to the requirements of the experiment and other aspects of the use of the unit, directly related to the company's interests, the general user can choose according to the following points:
1 , according to the company's products need to order
According to the needs of the company's products, the purpose of purchasing instruments is to ensure that the quality of the company's own products is controlled. Therefore, it is necessary to pay attention to the adaptability of the instrument to the company's products. For example, the pre-furnace test should be performed as fast as possible, and the incoming material inspection should be able to print. Test report, and finished product inspection must take into account the authority of the instrument. The single product such as steel, wire rope and other production units can reduce the professional requirements of the instrument, and companies such as cast copper alloys, aluminum alloys, stainless steel, etc. should pay special attention to the professionalism of the instrument, generally speaking, professional and strong instrument testing. More refined.
2 , purchase quality stable, timely service products
In terms of the quality, price and service of the instrument, it is mainly to consider the service ability of the instrument supplier.
3 , according to the size of the company decided to order
According to the scale of the company, the demand for equipment is generally divided into large, medium, and small categories. Large-scale enterprises can generally be equipped with high-frequency infrared carbon-sulfur analyzers and direct-reading spectrometers. The cost of laboratories can be controlled at around 300,000 yuan. Enterprises with relatively simple conditions and no economic prosperity may consider establishing non-aqueous carbon-sulfur analyzers , type 721 spectrophotometers, and domestic analytical balances to build laboratories, and build a 15 square laboratory with a total price of less than 10,000 yuan. . Like the vast majority of companies present, China is necessary to meet quality control needs, but also to achieve timely and accurate test can be configured to a higher degree of automation of the gas volumetric method of carbon and sulfur high-speed analyzer and a microcomputer element analyzer, the entire Laboratories cost between 15,000 yuan and 18,000 yuan. Non-ferrous metal manufacturers do not need to determine the content of carbon and sulfur elements, as long as the purchase of a computer multi-element analyzer and sample balance, together with all chemical glassware and a full set of chemical reagents, the total price will also be around one million.
4 , choose a reasonably priced product
Generally speaking, the service quality of the manufacturers is better than that of the merchants. The service of the sales outlets is relatively timely, but it also depends on the public services provided by various manufacturers to the society. Commitment content, especially considering the maintenance of the equipment outside the warranty period and the supply of spare parts and consumables.
