Improved Measurement Characteristics of Elemental Compositions Using Laser- Induced Breakdown SpectroscopyPages 22–35 Rapid detection of coal and fly ash is significant to improve the efficiency of thermal power plants and reduce environmental pollution. Given its fast response, high sensitivity, real-time, and noncontact features, laser-induced breakdown spectroscopy (LIBS) has a great potential for on-line measurement in these applications. The direct measurement of particles and gases using LIBS was studied, and the method was shown to be effective for this application.

Surface-Enhanced Raman Spectroscopy for Trace-Level Dimethoate Detection Based on a Silver Nanoparticle–Probe–Smooth Gold Film SubstrateIn this paper, we demonstrate a sensitive surface-enhanced Raman spectroscopy (SERS) substrate for trace dimethoate detection. The substrate is composed of Ag nanoparticle/probe/smooth Au film stack configuration. The nanogap formed by an Ag nanoparticle and a macroscopically flat Au film is one kind of “hot site” which will dramatically increase the total “hot spots” number.

Micro X-ray diffraction of cultural propertiesX-ray techniques play an important role in preservation and restoration science. In order to appraise the authenticity of cultural works and ensure proper preservation and restoration, it is crucial to carry out accurate analysis of materials while ensuring that they are not destroyed. This paper discusses the requirements for carrying out XRD measurements of cultural property samples using the latest micro-XRD instruments.

Optimization of the Electrospray Ionization Source with the Use of the Design of Experiments Approach for the LC–MS-MS Determination of Selected Metabolites in Human UrineSimultaneous quantification of metabolites in biological fluids, where they are present at different concentration levels, is usually a challenging analytical task. One of the steps that should be undertaken to increase analytical method efficiency is optimization of the electrospray ionization source (ESI), which can be especially helpful in increasing method sensitivity of agents with poor ionization characteristics. We present here a step-by-step ESI optimization strategy with the use of the design of experiments (DoE. This multivariate statistical approach allows effective evaluation of the effects of multiple factors and interactions among factors on a given response in a minimum number of experimental runs.
