Products are divided into eight separate lots; mass spectrometry, gas chromatography, gas chromatography with mass spectrometry, liquid chromatography, liquid chromatography with mass spectrometry, forthcoming systems and modular/ combined systems, accessories and consumables and equipment servicing.
When MS is combined with chromatography, gas chromatography (GC) for example, the analysis complexity is even greater--but so is the potential for much higher sensitivity and the ability to more effectively and efficiently separate and identify components.
The first part addresses research, discussing equipment and analytical methods for identifying metabolites including liquid chromatography, gas chromatography, mass spectrometry, and nuclear magnetic resonance spectroscopy.
There also have been changes in test equipment and instrumentation over the years, particularly in the analytical area where Fourier Transform IR, Gel Permeation Chromatography, Gas and Liquid Chromatography, GC Mass Spec, Thermal Analysis, Scanning Electron Microscopes, and other sophisticated hardware (all with software) have become standard equipment.
Complementary methods, based on the combination of mass spectroscopy with various chromatographic techniques such as high-performance liquid chromatography, gas chromatography and supercritical fluid chromatography are also covered in the book.
Contributors cover data analysis, micro extraction methods, supercritical fluid extraction, microwave assisted processes, ultrasound-assisted extraction, high performance liquid chromatography, gas chromatomography, comparative layer chromatography, I and chromatography, mass spectrometry and hyphenated instruments, food color analysis, high resolution near infrared and nuclear magnetic resonance analysis, nuclear magnetic resonance spectroscopy, atomic absorption atomic emission and inductively coupled plasma spectroscopies, autofluorescent spectroscopy, "electronic nose" technology, capillary electrophoresis, gel electrophoresis, multiplex immunoarrays, rheological instruments, scanning electron and transmission electron microscopy.
Although our raw materials are delivered with a Certificate of Analysis from the supplier, we identify raw materials to ensure proper potency and purity using advanced analytical techniques such as capillary electrophoresis, atomic absorption, UV/visible spectrophotometry, high pressure liquid chromatography, gas chromatography and microbiological testing where appropriate.
