NEWS Glass Expansion Newsletter | June 2017 | Issue 43 Dates and Events Dealing with a sample matrix high in total dissolved solids (TDS) is a common challenge for ICP spectrometry and generally most “real samples” analyzed by ICP laboratories contain considerable concentrations of TDS. These sample types include soils, sludge, wastewater, brines, high acid digests and fusions. The challenges associated with these samples include interrupted runs, signal drift, clogged nebulizers, shortened torch life, and greater interferences. Due to the popularity of these analyses the very first issue of the Glass Expansion Newsletter focused on methods to alleviate these challenges and improve ICP performance.1 In June of 2010 we released a follow up application note, covering both improvements in ICP design and new product releases pertinent to high salt matrices.2 Seven years have passed since our last “high TDS” application note and during this time frame there have been several new additions and updated designs to the Glass Expansion “high TDS” product line, in addition to new ICP spectrometer releases. Our current issue highlights the performance of these new sample introduction options, in addition to providing detailed maintenance procedures to reduce the frequency of replacement and help maintain the performance of the ICP sample introduction system. We also included an appendix with references from a wide range of ICP manufactures covering high TDS applications utilizing the newest instrument releases. The goal of this issue of the Glass Expansion Newsletter is to provide up-to-date guide and useful tutorial for analyzing real samples by ICP spectrometry. Sample Introduction System An argon humidifier is one of the most important accessories for ICP-OES and ICPMS analyses involving samples with high concentrations of TDS. The added moisture in the nebulizer gas helps to reduce salt deposits in the nebulizer and torch injector, allowing uninterrupted ICP operation. In addition to the argon humidifier, a large bore injector is recommended, typically, greater than 1.5mm ID for radial view ICPOES instruments and greater than 2.0mm ID for axial view ICP-OES and ICP-MS instruments. Due to the rapid devitrification of quartz in the presence of high TDS, a demountable ICP torch is preferred to reduce replacement costs. A nebulizer capable of handling a high amount of TDS should be chosen and combined with a baffled cyclonic spray chamber to eliminate large droplets from reaching the torch. A wide selection of Glass Expansion products will be on display at the following exhibitions. The display will include nebulizers, spray chambers, torches, RF coils, ICP-MS cones and accessories. Glass Expansion specialists will be on hand to answer your questions and assist you to choose the optimum components for your ICP.
