Carburization is a common method of hardening steel surfaces to be wear-resistant for a wide range of mechanical processes. One critical characteristic of the carburization process is the increase in carbon content that leads to the formation of mart

The focus of this dissertation is the use of a twin quadrupole inductively coupled plasma mass spectrometer (ICP-MS) for the simultaneous detection of two m/z values. The twin quadrupole ICP-MS is used with laser ablation sample introduction in both

Background Walk Score ® is a nationally and publicly available metric of neighborhood walkability based on proximity to amenities (e.g., retail, food, schools). However, few studies have examined the relationship of Walk Score to walking behavior. P

This report is concerned with the first investigation of a direct injection high efficiency nebulizer (DIHEN) as a microliter-solution introduction system for axial inductively coupled plasma time-of-flight mass spectrometry (ICP-TOFMS). The effect o

A standard additions method for calibrating the response of laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) is assessed. Desolvated particles from an ultrasonic nebulizer and particles from an ablation cell are introduced simul

Laser ablation (LA) is used with steel samples to assess the ability of a twin quadrupole inductively coupled plasma mass spectrometer to eliminate flicker noise. Isotopic and internal standard ratios are measured in the first part of this work. Resu

The ion beam from the inductively coupled plasma (ICP) is split into two parts by a device comprised of two electrostatic analyzers in a back-to-back arrangement. Each ion beam is then monitored by a separate quadrupole mass analyzer and electron mul

The isotope ratio performance of an axial time-of-flight ICP mass spectrometer (Renaissance TOF-ICPMS, LECO Corp.) was evaluated. The isotope ratio precision, expressed as the relative standard deviation (RSD) for 10 successive measurements, was eval
