Abstract

Speciationanalysis hasevolved into anvaluable toolin human health risk evaluation,environmental survey and food quality control.The eventualimpact of an element will be dictated by particular species of forms of the element,rather than its total concentration.Separation and detection of species of several elements in single analytical run can be accomplished by gas chromatography and Fourier transformer infrared spectroscopy(GC-FTIR).Although various methods are available for speciation analysis.Thehyphenated technique is developed from the coupling of a separation technique and an online spectroscopic detection technology. Hyphenated analytical techniqueis onlinecoupling of separation and detection technique using suitable interfaces. The remarkable improvements in hyphenated analytical methods over the last two decades have significantly broadened thereapplications in the analysis of biomaterials especially natural products. Combining of chromatographic system online with spectroscopic detector in order to obtain structural information regarding analytes present in the sample has become the most important approach for the identification and confirmation of the identity of target and unknown chemical compounds. They improve resolution and sensitivity along with the decreased analysis time.
