Trident CT Internal Standard Kit. In-line addition of internal standards and ionization buffers provides an efficient means of accurately and precisely dosing all of your samples without extra effort or the risk of error or contamination. Internal standardization (IS) is often used to compensate for physical and mass-space interferences in ICP spectrometry. It can also enhance short-term and long-term reproducibility. The Trident CTTM In-Line Reagent Additions Kit offers a more compact and efficient mixing chamber, with leak-free seals and zero dead volume connections. Moreover, it is completely modular, so that any damaged or lost components can be replaced easily.For solutions containing HF use Trident IS Kit for HF P/N NC2046964, 60-808-1150.Replacement parts include 60-808-1187, 70-803-1871, 70-803-1870, NFT-16-50-300, EZT-16-50-300, 60-703-1119, 70-803-0749, 70-803-0748, 70-803-1350.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
