Calixarenes as Stationary Phases in High Performance Liquid Chromatography
Jul 01, 2007; ... Calixarenes are a class of host molecules with three-dimensional cavity capable of accepting guest molecules. The interest of calixarenes in analytical and separation chemistry has increased in recent years because of their ability to form reversible complexes with both neutral and charged ...
Letter from the Editor
Jan 01, 2007; ... Dear Readers: Welcome to another year of the Journal! The list of papers already accepted spans a wide view of analytical measurement science! Our theme issue on chemometrics is now in print, and I can remember more than 6 years ago, when it was just an idea. Such issues, where a ...
Current Status of Methods and Techniques for Breath Analysis
Jan 01, 2007; ... Due to the great potentials in clinical diagnosis, disease state monitoring, and environmental exposure assessment, the breath test is becoming one of the most desirable noninvasive procedures for clinical diagnostics. This article reviews the technical aspects of breath analysis including ...
Modern Techniques of Sample Preparation for Determination of Organic Analytes by Gas Chromatography
Jan 01, 2007; ... The majority of techniques currently applied for isolation/enrichment of organic analytes from gaseous and liquid samples are based on extraction and utilize solid absorbents or organic solvents. While techniques fulfill their tasks, they reveal some important inconveniences. In the case of ...
Online Sample Pretreatment Systems for Determination of Cadmium by the ETAAS Method
Jan 01, 2007; ... Trace and ultratrace determinations of cadmium in environmental and biological samples have become of increasing interest due to the high toxicity of this metal and because electrothermal atomic absorption spectrometry is probably the method of choice for its determination. The measured signals ...
Letter from the Editor
Jan 01, 2007; ... Dear Readers: During my service as Editor-in-Chief, the Journal has had periods of emphasis on environmental chemistry and most recently a double issue on chemometrics. I plan to continue to consider suggestions for "emphasis issues" but not at the expense of articles from all the areas ...
Chemometric Estimation of Natural Water Samples Using Toxicity Tests and Physicochemical Parameters
Jan 01, 2007; ... The present study deals with the assessment of the quality of natural waters by the use of chemometric interpretation of monitoring data from physicochemical parameters and toxicity tests. The data set consists from data originating from the Turawa reservoir (surface water, sediment core water ...
Application of Different Sampling Procedures in Studies of Composition of Various Types of Runoff Waters-A Review
Jan 01, 2007; ... Runoff waters are one of the forms in which precipitation reaches the ground and surface waters. They are formed when rain or melting snow washes the surfaces of roofs, highways, agricultural areas or tree canopies. Pollutants present in runoff waters can constitute a potential danger to aquatic ...
Indirect Photometric and Fluorometric Detection in High-Performance Liquid Chromatography: A Tutorial Review
Jan 01, 2007; ... A review of indirect photometric and fluorometric detection in high-performance liquid chromatography (HPLC) is presented. A functional definition of indirect detection, somewhat broader and simpler than what was often used to characterize these techniques, was employed for this review. Emphasis ...
Application of Ionic Liquids in Liquid Chromatography
Jan 01, 2007; ... Interest in ionic liquids (ILs) for their potential application in analytical chemistry continues to grow. Their usefulness can be due to favourable physicochemical properties, like the lack of vapour pressure, good thermal and chemical stability as well as very good dissolution properties ...
Analytical Methods for the Determination of Organic Acids in Honey
Jan 01, 2006; ... Although organic acids represent less than 0.5% of honey's constituents, they make important contributions to organoleptic, physical, and chemical properties of honey. They could be used as fermentation indicators, for the treatment of Varroa infestation, and to discriminate among honeys ...
Review of Univariate Standard Addition Calibration Procedures in Flow Analysis
