1. The selection principle should be determined first: the most scientific and realistic principle is application, that is, performance satisfaction. What materials are you testing? Which elements are tested? What is the content range of the element? Then take a representative sample or several samples to the supplier for proofing and on-site testing to identify whether the equipment can meet its own testing requirements. It is best to treat the samples uniformly, because different manufacturers have different processing methods, which will also affect the test results.
The purpose of on-site testing is to be able to see the real test data on the one hand, and on the other hand to examine the company’s production scale, R&D capabilities, product appearance, production process, comparison of materials used, etc.
2. If the performance of the equipment is satisfied, the next step is the price. Because of the different market structure, different brands of instruments may have different distribution channels. Some brands will adopt the direct selling model, some will adopt the agency model, and some will adopt the dealer model. Nine-nine-one, as users Regardless of the model, you only follow a principle that the price is within your budget and meets the market's price quotation. Don't raise the budget because the manufacturer blindly brags about the company's size. What you buy is an instrument that meets your testing requirements. You cannot buy the company. The company is large, and the instrument is useless.
3. After the first two points are settled, the supplier's after-sales service capability is the work that has to be considered. You can ask the supplier to provide a list of user representatives in the same industry as a reference. In addition, ICP spectrometer is a highly professional instrument, and it is a precise analytical instrument. The manufacturer's production years and professionalism are closely related to after-sales. In addition, the utilization rate of instruments sold to government agencies will be slightly lower than those sold to manufacturers. Therefore, observing whether there are many manufacturers or other organizations is also one of the ways to judge after-sales service. Of course, it is not absolute.
The above are a few introductions about choosing a high-quality and suitable ICP spectrometer for reference only. But no matter which manufacturer's instrument you choose, it will always change. Meet the corporate testing requirements, the price is right, and the after-sales service is timely.
