Understanding the Fundamental Components of Sample Introduction for ICP-OES and ICP-MS

Spectroscopy, 2022
Analytical techniques based on inductively coupled plasma (ICP) are commonly used for analyzing the elemental composition of a sample and are widely applied in analytical testing laboratories. Particularly for larger laboratories, analysis time and throughput are essential performance indicators, which can be severely impacted if sample analysis needs ...

Multisignal calibration in spark- and ICP-OES

Fresenius' Journal of Analytical Chemistry, 1994
The advantages of multivariate calibration by using more than one selective emission line for one analyte are described in comparison with univariate calibration. Principle component regression (PCR) and partial least squares regression (PLS) are compared with classical univariate linear regression of single lines.

Determination of Thorium by ICP-MS and ICP-OES

Radiation Protection Dosimetry, 2001
Natural thorium (232-Th) has traditionally been measured by radiometric techniques such as alpha and gamma spectrometry. However. with both ICP-OES and ICP-MS instruments becoming relatively common in many analytical laboratories. these techniques have become more acceptable in thorium analysis.

Solid-state detector for ICP-OES

Analytical Chemistry, 1993
A new type of solid-state detector has been designed to meet the needs of inductively coupled plasma optical emission spectroscopy (ICP-OES), including high quantum efficiency in the UV, low noise, wide dynamic range, rapid readout, broad spectral coverage, and high spectral resolution.

Application of ICP-OES and ICP-MS in materials analyis

2022
Characterization of historical and modern samples is very important in materials engineering. In historical samples, valuable cultural heritage needs preservation and the obtained results dictate decisions on cleaning, conservation and restoration steps.

Determination of elevated concentrations of bromine in serum by ICP-MS and ICP-OES

Journal of Analytical Atomic Spectrometry, 2005
The inorganic and organic components of 100-fold diluted serum enhance the signal of 79Br+ in ICP-MS by about 13%. Sodium and albumin are the main causes of the effect. Different calibration procedures were investigated to compensate for the enhancement interference.

การวิเคราะห์ผลของตัวกลางต่อสัญญาณของปรอท และการตกค้างของปรอทที่ความเข้มข้นสูงระหว่างการตรวจวัดด้วยเครื่อง ICP-OES

2016
ปรอท (Mercury (Hg)) เป็นธาตุที่มีอยู่ตามธรรมชาติ สามารถถูกปลดปล่อยออกมาสู่สิ่งแวดล้อมผ่านการกระทำของมนุษย์ ปรอทเป็นธาตุที่มีความเป็นพิษสูงทั้งต่อสิ่งมีชีวิตและสิ่งแวดล้อม ด้วยเหตุนี้ การวิเคราะห์เพื่อหาความเข้มข้นของปรอทในตัวอย่างสิ่งแวดล้อมจึงมีความสำคัญเป็นอย่างยิ่ง โดยทั่วไปแล้วการวิเคราะห์ปริมาณของปรอทในตัวอย่างนั้น จะต้องเริ่มด้วยการดำเนินการย่อยตั
