Some Considerations in Purchasing Analytical Instruments

1, according to the company's products need to order According to corporate product needs, the purpose of purchasing instruments is to ensure that the company's own product quality is controlled, so we must pay attention to the adaptability of the instrument to the company's products, like the pre-fire test as fast as possible to test, come Material inspections are best able to print test reports, and finished product inspections 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 accurate and convenient.

2, according to the size of the company decided to order According to the size of the enterprise analytical instrument demand 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 1 million yuan. Enterprises with relatively simple conditions and no economic prosperity may consider setting up non-aqueous carbon-sulfur analyzers, Type 721 spectrophotometers, and Model 328AB analytical balances to build laboratories, and build a 15 square laboratory with a total price of less than 10,000 yuan. yuan. As most domestic enterprises in China currently have to meet quality control needs and do timely and accurate tests, they can be equipped with a high-volume carbon-sulfur high-speed analyzer and a computer element analyzer. 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.

3. The quality, price and service of product analysis instruments with stable quality and timely service are mainly considering the service capabilities of instrument suppliers. At present, the quality of high-end product instruments such as large-scale direct-reading spectrum is better than domestic products. The prices are not comparable, and the quality and performance of domestic mid-range instrument products are much the same, and the functions are slightly different.

4, buy a reasonable price of the product in service Generally speaking, manufacturers than the merchant service quality is better, there are sales outlets more timely services, but also depends on the various manufacturers of social open services. Commitment content, especially considering the maintenance of the equipment outside the warranty period and the supply of spare parts and consumables. The following provides some instrument manufacturers information: customers can have a selective comparison.
