Triple-Quadrupole ICP-MS Provides Improved Performance for Difficult Polyatomic and Isobaric Overlaps on Lead Isotopes
Triple-quadrupole inductively coupled plasma–mass spectrometry (ICP-MS) can operate in MS-MS mode, which offers the potential to improve the removal of spectral interferences compared to conventional quadrupole ICP-MS with a collision–reaction cell, or high-resolution ICP-MS. In this article we describe how an application that has proved problematic for quadrupole ICP-MS and high-resolution ICP-MS can be addressed using a reaction gas method with triple-quadrupole ICP-MS.

Optimizing the Sample Preparation of Metals: Single-Reaction-Chamber Microwave Digestions for Contract Analytical Laboratories
Contract analytical laboratories use a variety of instrumentation for trace-metal analysis and must take advantage of method standardization whenever there is an opportunity. To ensure high quality data and a standard operation for a variety of industrial samples, these laboratories use microwave digestion for sample preparation before inductively coupled plasma–optical emission spectrometry (ICP-OES) or ICP–mass spectrometry analysis. This article describes optimized single-reaction-chamber microwave digestion methods, including vessel selection, sample size, and temperature profiles, along with ICP-OES data. MORE »

Elemental Detection of Semiconductor Process Gases Using a Gas-Exchange Device Coupled to ICP-MS
This article describes the direct measurement of trace levels of organometallic process gases in semiconductor manufacturing environments using a gas-exchange device coupled with quadrupole inductively coupled plasma–mass spectrometry (ICP-MS). By passing ambient air through the gas-exchange device, the organometallic gas molecules in the sample are quantitatively extracted and transferred to the ICP-MS system for detection as the metallic species. The combined system and analysis approach are summarized, and fully quantitative calibrations are included. MORE »

Application Note
DST-1000 Acid Purification System
Don Potter, Savillex
The Savillex DST-1000 Acid Purification System produces high purity acid from low cost trace metal grade acid. It can be used to purify HNO<sub>3</sub>, HCl, and HF. The DST-1000 can pay for itself in a short period of time through the cost savings by using trace metal grade acid instead of bottled high purity acid. Learn more>>
