The main common and potent technique for the research of advanced multicomponent combos of risky elements is fuel chromatography. even though, there are many barriers asso ciated with the classical version of this method which retard its improvement and the extra growth of its program: 1) the id of the elements of a fancy combine ture of unknown composition is in itself a fancy and hard challenge, until the homologous sequence of the element of be pointed out is understood; 2) the overlapping of chromatographic peaks for a number of compounds makes it tough, and in a couple of circumstances very unlikely, to hold out qualitative and quantitative research of those elements, and results in the need of utilizing numerous columns of other polarities or to using columns with very excessive potency; three) the direct research of volatile and nonvolatile compounds is very unlikely; four) the trouble of quantitative chromatographic research utilizing thermal conductivity detectors raises with the need of making a choice on person reaction (calibration) components; the insensitivity of the flame ionization detector to a couple of components (inorganic gases) results in the need of introducing extra operations (prelimi nary focus of hint elements) in reference to thermal conductivity detectors. vii viii FOREWORD The directed use of chemical conversion of the compounds analyzed frequently makes it attainable to take away the restrictions stated above.

Mycobacterium tuberculosis is without doubt one of the so much infamous pathogens in the world, inflicting the dying of roughly 1. five million humans each year. a huge challenge within the struggle opposed to tuberculosis is the emergence of traces that experience obtained resistance to all on hand antibiotics. One key to the luck of M.

Time, sec It should be pointed out that, independently of the above discussedpublication, an analogous method was developed by Berezkin et al.  when studying the kinetics of bimolecular chemical reactions by impulse chromatography; in this case the chromatographic system incorporated two detectors, so that chromatographie and kinetic data could be obtained in a single experiment. In the chromatographic system employed  the column preceded the reactor, which made it possible to study the kinetics of the chemical reaction of the compounds in a pure form without separating them first.
This complex system can be considered as a combination of systems 0 and 3. It might be convenient to use for the qualitative identification of pure compounds and compounds which were first separated in a chromatographic column, and also for the group analysis of complex mixtures, specific absorption reactions according to the systems developed by Franc and Michajlova . In this system the 50 CHROMATOGRAPHIC SYSTEMS identification of the unknown compound is accomplished by means of its retention times in several parallel columns with different stationary phases.
