QA Kit. The Quality Assurance (QA) Kit enhances the day-to-day reproducibility of your results and greatly reduces the chance of a clogged nebulizer. It's a convenient QA package combining the TruFlo Sample Monitor (501907281), Inline Particle Filter (NC0897716), Eluo Nebulizer Cleaning Tool (NC9462559) and Eluo Adaptor for Inline Filter (NC0801128). The Inline Particle Filter is easily spliced into the autosampler probe capillary before the peristaltic pump and switching valve, which greatly reduces the risk of a blocked nebulizer. The TruFlo instantly detects any reduction in the sample flow due to particulates trapped in the filter. The Eluo and the Adaptor provide a quick & effective way to backflush the filter and minimize any downtime.The TruFlo provides continuous real-time flow measurement, sounds out-of-range alarm, stores 24 hours of data, and is suitable for all ICP-OES and ICP-MS instruments.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
