Separation of hydrophobic metabolites using monolithic silica column by high-performance liquid chromatography and supercritical fluid chromatography (CAT#: STEM-CT-0070-LJX)

Introduction

Monolithic silica columns have very low back-pressures and offer several advantages over conventional columns packed with spherical particles, such as high separation efficiency and rapid analysis. In this service, we use monolithic silicon columns to analyze complex hydrophobic metabolites. We used monolithic columns in high performance liquid chromatography and developed a separation technique for high-speed, high-resolution analysis of natural polypentenol geometric analogs.




Principle

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.

Applications

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

Procedure

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

Materials

• Sample Type:
Hydrophobic metabolites

Notes

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.
