The development of cation-exchange chromatography in free amino acids analysis

Although it was not called a liquid chromatograph, the first such instrument was introduced in late 1959 by Beckman Instruments and was designated the M.S. Amino Acid Analyzer in honour of Moore and Stein. Inject valves had yet to be invented, the buffer switching valves were glass stopcocks and the column temperature was controlled by circulating water baths. Two positive displacement pumps ...

Development of a novel odor measurement system using gas chromatography

This paper describes a novel odor measurement system for creating arrays of virtual chemical sensors with nonoverlapping responses using ultrahigh-speed gas chromatography with a surface acoustic wave sensor (GC/SAW). This GC/SAW system provides high-resolution twodimensional olfactory images for easy recognition of many complex odors. Separation and quantification of the individual chemicals ...

Gas Chromatography: MCERTS Certification for Ambient Air Analysis on Benzene and VOCs

Due to environmental issues, the world of gas analysis is evolving very rapidly. Governments set the rules to limit and control the environmental pollution through legislation. Volatile organic compounds (VOCs), often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

High-Resolution Ultrahigh-Pressure Long Column Reversed-Phase Liquid Chromatography for Top-down Proteomics

Separation of proteoforms for global intact protein analysis (i.e. top-down proteomics) has lagged well behind what is achievable for peptides in traditional bottom-up proteomic approach and is becoming a true bottle neck for top-down proteomics. Herein, we report use of long (≥1 M) columns containing short alkyl (C1-C4) bonded phases to achieve high-resolution RPLC for separation of ...

Application of Lab-on-a-chip Technology in Water Analysis

The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those ...

Degradation and toxicity depletion of RB19 anthraquinone dye in water by ozone-based technologies

This research investigated the discoloration and mineralization of Reactive Blue 19 (RB19) anthraquinone dye by single ozonation, single UV radiation and ozonation jointed with UV radiation (O3/UV). The problem was approached from two points of view: with the objective of color removal or the mineralization of solution. In each case, the optimum operating conditions were different. Ozonation ...

Advanced gas detection technology supports arctic greenhouse gas research

Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

Rapid Field-Screening of Waste Oil/Solvent Drums with Horizontal ATR / Fast-Screening IR Spectroscopy

While the growth of technology and industry has given us a high standard of living, it has also given us a greater amount of waste products to deal with. A significant portion of the waste is either buried underground or stored in abandoned warehouses. Some of this waste material may be harmless and innocuous, and some may be quite hazardous; but all of it must be tested by some procedure to ...

Identification of metabolites produced by Phanerochaete chrysosporium in the presence of amlodipine orotate using metabolomics

Pharmaceuticals are very useful in treating human diseases but they are excreted to the environment sometimes in their original form or as byproducts of human metabolism. Pharmaceuticals and their metabolites have been proven by studies to be harmful to non-target ecological species and may be persistent in different water matrices. In this regard, there is an emergent need to eliminate these ...
