Supercritical Fluid Chromatography (SFC): High-Efficiency Separation for Modern Laboratories

Wiki Article

Supercritical Fluid Chromatography(SFC) is an advanced separation technique that combines the advantages of liquid chromatography (LC) and gas chromatography (GC). Using supercritical carbon dioxide (CO₂) as the primary mobile phase, SFC delivers fast, efficient, and environmentally friendly separations. Today, SFC is widely adopted in pharmaceutical, biopharmaceutical, chemical, and research laboratories for both analytical and preparative applications.

Intech Analyticals offers state-of-the-art Supercritical Fluid Chromatography systems designed to meet the growing demand for high-precision, scalable, and cost-effective separation solutions.

What is Supercritical Fluid Chromatography?

Supercritical Fluid Chromatography utilizes a fluid maintained above its critical temperature and pressure, where it exhibits properties of both a gas and a liquid. Carbon dioxide is most commonly used due to its low critical point, non-toxic nature, and excellent solvating power when combined with suitable modifiers.

This unique mobile phase enables faster mass transfer, lower viscosity, and higher diffusivity compared to traditional liquid chromatography, resulting in superior separation efficiency and reduced analysis time.

Key Advantages of Supercritical Fluid Chromatography

1. Faster Analysis Time
SFC systems allow rapid separations due to the low viscosity and high diffusivity of supercritical CO₂, significantly improving laboratory throughput.

2. High Resolution and Selectivity
SFC delivers excellent resolution for complex mixtures, making it ideal for chiral separations and structurally similar compounds.

3. Eco-Friendly Technology
With reduced organic solvent consumption, SFC is considered a green chromatography technique, supporting sustainable laboratory practices.

4. Easy Solvent Removal
CO₂ easily evaporates after separation, simplifying sample recovery and reducing downstream processing time.

5. Scalable from Analytical to Preparative
SFC is suitable for method development, analytical testing, and large-scale purification, offering seamless scalability.

Applications of Supercritical Fluid Chromatography

Supercritical Fluid Chromatography is widely used across multiple industries:

• Pharmaceutical Industry: Chiral separations, impurity profiling, and active pharmaceutical ingredient (API) purification

• Biopharmaceuticals: Purification of complex biomolecules and intermediates

• Fine Chemicals: Separation of isomers and structurally similar compounds

• Food & Flavor Industry: Analysis of lipids, additives, and natural products

• Research & Academia: Method development and advanced analytical studies

Intech Analyticals provides SFC systems that are engineered to deliver reliable performance across all these application areas.

Analytical vs Preparative SFC Systems

Analytical SFC is primarily used for qualitative and quantitative analysis, offering high sensitivity and accuracy. It is ideal for research laboratories, quality control, and method development.

Preparative SFC, on the other hand, is designed for purification at larger scales. It enables high-throughput compound isolation with excellent recovery and purity, making it suitable for pharmaceutical manufacturing and pilot-scale operations.

Intech Analyticals supports both analytical and preparative SFC requirements with customizable system configurations.

Key Components of an SFC System

A typical Supercritical Fluid Chromatography system consists of:

• CO₂ delivery and pressurization module

• Modifier pump for co-solvents

• High-precision injector
