On-line heart-cut LC–GC and, more recently, comprehensive LC–GC (LC×GC) are very powerful analytical techniques because of the combination of the selectivity features of LC with the high efficiency of GC. Such a combination can overcome the drawbacks related to sample manipulation in off-line approaches because of the automation of the transfer procedure. Dirty samples, or non-volatile components, can be pre-purified in the LC step, allowing the transfer to the GC system of the volatile fraction, or of selected fractions, exploiting the high selectivity of the LC process. This article presents an overview of the most recently used interfacing systems, as well as applications in the food analysis.

Abstract
On-line heart-cut LC–GC and, more recently, comprehensive LC–GC (LC×GC) are very powerful analytical techniques because of the combination of the selectivity features of LC with the high efficiency of GC. Such a combination can overcome the drawbacks related to sample manipulation in off-line approaches because of the automation of the transfer procedure. Dirty samples, or non-volatile components, can be pre-purified in the LC step, allowing the transfer to the GC system of the volatile fraction, or of selected fractions, exploiting the high selectivity of the LC process. This article presents an overview of the most recently used interfacing systems, as well as applications in the food analysis.Pubblicazioni consigliate
