Portable liquid chromatographs

Abstract

       In short survey a specification on portable liquid chromatographs are resulted: emersion stories, composition, applied detectors, columns, pumps and fields of application. The list of commercial portable liquid chromatographs is resulted. Miniaturization of instruments - one of the basic trends of development in a chromatography. Prime areas of application of portable liquid chromatographs is an analysis in situ events
or incidents: it is control of a environment, foodstuff in the markets and supermarkets, clinical analyses at bed of the patient, forensic analyses, etc. Portable liquid chromatographs should have a small size and weight, should work autonomously and safely, to have low power consumption and supplies. The basic detectors used in portable liquid chromatographs - UV on light-emitting diodes and electrochemical. The basic
push to development of portable liquid chromatographs was yielded by working out of a portable electroosmotic high-pressure pump. In portable liquid chromatographs capillary columns, nanocolumns and micropacked columns are used. It is in certain cases used even gradient elution. About ten corporations began working out or already release portable liquid chromatographs for bioanalyses, diagnostics of diseases, control of pollution. Also as detectors, except aforementioned, mass-spectrometer, fluorimetric and chemiluminescent began to be used. Undoubtedly, it is necessary to expect new portable liquid chromatographs.
