Trident Internal Standard Kit for HF. 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 In-Line Reagent Additions Kit offers a more compact and efficient mixing chamber that is compatible with HF. Moreover, it is completely modular, so that any damaged or lost components can be replaced easily.Replacement parts include 60-808-1124, 60-808-1187, UFT-EZT-16-50, EZT-16-50, EZT-16-25, NC1150995, KK711E.For solutions without HF use Glass Expansion’s Trident CT Internal Standard Kit (P/Ns NC2046960, 60-703-1179).Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
