Which compound is Analysed by SFC?

The principles of SFC are similar to those of liquid chromatography, however SFC typically uses carbon dioxide as the main mobile phase. SFC is essentially a normal-phase chromatographic technique with inherent high speed and efficiency due to its mobile phase.

Which of the following is an absorption detector used in SFC?

An ultraviolet detector with a capillary flow cell is evaluated for use as a refractive index detector in supercritical fluid chromatography (SFC) using a CO 2 mobile phase. The temperature or pressure control or both of the cell is critical to minimize density-related refractive index changes.

Which detector is used in SFC?

Many of the detectors commonly used in gas chromatography (GC) and liquid chromatography (LC) have been interfaced to SFC. Detectors from GC have become the most widely used detectors in SFC.

Which one is the advantage of SFC over GC?

The advantages of SFC over liquid chromatography (LC) include higher efficiency separations and faster speed of analysis. The advantage that SFC has over gas chromatography (GC) is that SFC can efficiently separate thermally labile compounds. The disadvantage of SFC is that the polarity of the mobile phase is limited.

Why is SFC accepted as a column chromatography method?

Supercritical fluid chromatography is accepted as a column chromatography methods along with gas chromatography (GC) and high-performance liquid chromatography (HPLC). Due to to the properties of supercritical fluids, SFC combines each of the advantages of both GC and HPLC in one method.

Which is the best method to test for SFC?

Direct measurements of SFC by NMR (nuclear magnetic resonance) provides quick and accurate determination of SFC value. NMR as method of fats and oils analysis is included in the following international standards: AOCS Cd 16b-93 revised in 2000 (in USA) ISO 8292 (in Europe)

What are the applications of supercritical fluid chromatography?

The discovery of supercritical fluids led to novel analytical applications in the fields of chromatography and extraction known as supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE).

How is solid fat content ( SFC ) determined?

Solid Fat Content (SFC) is generally accepted analysis of fats and oils in the food industry. The traditional extraction methods for SFC determination are slow, irreproducible and require additional chemicals.
