The same measurement principle is used in both products. The COM-3010PROX has the following features compared to the EB-17.

The parallel flat plate type detector is used in many lower-priced ion counters found in the market. This detector can provide unstable measurement as it disrupts the flow of the intake air in the detector. Yes, it does. The COM-3010PROX detects negative ions generated when the air is ionized by radiation. Lee BU, et al. (2004). Removal of fine and ultrafine particles from indoor air environments by the unipolar ion emission. DOI:

Once all the tests have been completed, provide the class with an unknown solution X and ask the students to identify either the positive ion present, the negative ion present or both. Further practical activities and context You first acidify the solution you are testing with dilute hydrochloric acid and then add barium chloride solution. Technician notes and integrated instructions are available to support all of the tests in this video.The chloride precipitate is obviously white, but the other two aren't really very different from each other. You couldn't be sure which you had unless you compared them side-by-side. Use of appropriate qualitative reagents and techniques to analyse and identify unknown samples or products including gas tests, flame tests, precipitation reactions, and the determination of concentrations of strong acids and strong alkalis Details of alternative methods to carry out the flame tests. This activity makes a good plenary or starter; asking students to name the metal ion as they see the different flame colours. The flame tests infographics is a great reference sheet and also explains the chemistry behind the flame colours. The chemistry of fireworks infographic and sparklers infographic provides a nice teaching context. You may also be interested in the exhibition chemistry video Rainbow flame demonstration, which provides a wonderful display of colours as well as further details of the chemistry of flame tests. Key terms You can also do this test using barium nitrate solution and dilute nitric acid. A simple way of remembering what acid is safe to use is to choose the one related to the barium compound you are using. This is another test where the substance you are testing has to be in solution, and involves reacting it with dilute nitric acid and silver nitrate solution.
