Abstract Mass spectrometry (MS) is considered today as one of the most popular detection methods, due to its high selectivity and sensitivity. In particular, this detector has become the gold standard for the analysis of complex mixtures such as biological samples. The first successful SFC-MS hyphenation was reported in the 80's, and since then, several ionization sources, mass analyzers and interfacing technologies have been combined. Due to the specific physicochemical properties and compressibility of the SFC mobile phase, directing the column effluent into the ionization source is more challenging than in LC. Therefore, some specific interfaces have to be employed in SFC-MS, to i) avoid (or at least limit) analytes precipitation due to CO2 decompression, when the SFC mobile phase is not anymore under backpressure control, ii) achieve adequate ionization yield, even with a low proportion of MeOH in the mobile phase and iii) preserve the chromatographic integrity (i.e. maintaining retention, selectivity, and efficiency). The goal of this review is to describe the various SFC-MS interfaces and highlight the most favorable ones in terms of reliability, flexibility, sensitivity and user-friendliness.
