Profiling of targeted phytosterols by a fast ultra performance supercritical fluid chromatography-tandem mass spectrometric method (CAT#: STEM-CT-0050-LJX)

Supercritical fluid is a substance that has both gaseous and liquid properties above the critical point. Supercritical fluids have the advantages of high diffusion coefficient, low viscosity, adjustable solubility and high vapor phase density, so they can provide efficient mass spectrometry ionization and separation results.
Supercritical fluid chromatography (SFC) is an efficient separation technique that uses supercritical fluid as a mobile phase. The samples are packed into short tubes or SPE columns, and the samples are compressed and regulated by supercritical fluid to obtain good solubility. The sample components are then separated by column interaction, thus achieving the separation of different compounds.

For efficient separation of substances
Widely used in biology, chemistry, environmental protection and other fields

1. Sample injection
2. The high pressure pump increases the pressure of the sample and mobile phase
3. The sample and mobile phase enter the chromatographic column
4. Flow limiter assists sample separation

• Sample Type:
Phytosterols

1. In the process of separation, the control of pressure and temperature of supercritical fluid is very important, which affects the properties and separation efficiency of supercritical fluid.
2. In addition, the selection of the appropriate column, packing and moving equivalent factors will also affect the separation effect.
