The operation of ICP and ICP-MS instruments can be a challenge at times, especially when dealing with complex samples.
You may have run into a sudden change in analyte sensitivity or received an odd error message. Many ICP and ICP-MS users
rely on their co-workers for help, but there are also a number of helpful resources available to the ICP community.
Glass Expansion web site, www.geicp.com
Our web site has a number of very useful facilities to help the ICP analyst choose the best components and operating conditions.
Selection Guides
Under PRODUCTS>NEBULIZERS, there is a link to a nebulizer selection guide (shown in Figure 1). This has recently been updated
to include new nebulizers. It gives the analyst a step by step approach to narrowing down the best nebulizer for the application.
Similarly, under PRODUCTS>SPRAY CHAMBERS, a guide to selecting the best spray chamber is available (Figure 2).
