Solid Phase Extraction (SPE) Columns & Cartridges
What Is Solid Phase Extraction (SPE)?
Solid Phase Extraction (SPE) is a sample preparation extractive technique used in laboratories to clean-up, solvent switch, and concentrate samples prior to analysis, particularly with methods like high-performance liquid chromatography (HPLC) or gas chromatography (GC). Solid phase extraction is essential for getting specific separations in complex mixtures by isolating target analytes while removing unwanted contaminants, which helps achieve more accurate and precise analytical results.
Phenomenex offers advanced sample preparation with its wide selection of SPE products, engineered for exceptional reliability and precision in analytical testing.
Phenomenex’s SPE products, with their targeted selectivity and robust capabilities, are crucial in producing cleaner samples to reduce interferences and premature column failure. This, in turn, significantly improves the accuracy and precision of HPLC and GC analyses, making them indispensable tools for achieving high-quality analytical results.
Overview
How Does Solid Phase Extraction Work?
Solid phase extraction is a highly effective method utilized in chromatography for preparing samples for further analysis. It involves multiple steps designed to isolate specific analytes from complex or dirty mixtures, resulting in cleaner, more concentrated samples, and suitable for accurate analysis. The process is straightforward, following a sequence of steps: condition, equilibrate, load, wash, and elute. Each step is essential in ensuring targeted selectivity, versatility, and can be used in conjunction with automation to ensure further optimization, but some types of sorbents may require additional steps or even fewer steps for a clean sample.

Benefits of Using Solid Phase Extraction
The principles of solid phase extraction, a fundamental technique in sample preparation, revolve around selectively isolating specific analytes, making SPE a crucial step in many laboratory workflows. Here are the key benefits of using SPE:
- Targeted Selectivity: The principles of solid phase extraction emphasize the ability to retain and isolate specific analytes from complex mixtures selectively. By using a solid phase extraction cartridge, SPE ensures that the compounds of interest are captured while impurities and unwanted substances are effectively removed. This targeted selectivity leads to cleaner samples, which is essential for accurate and reliable analytical results.
- Versatility: SPE is highly versatile and can be applied to various sample types, viscosities, and volumes. Solid phase extraction cartridges are available in multiple tube or 96-well plate sizes with variable sorbent volumes to accommodate different needs, whether working with small biological samples or large environmental matrices. This versatility allows SPE to be used across various industries, including pharmaceuticals, environmental testing, food safety, and many others.
- Easy Automation: SPE is well-suited for automation, allowing for the streamlined processing of numerous samples with minimal manual intervention. Automated SPE systems use solid phase extraction cartridges or 96-well plates to handle large sample batches quickly and consistently, making SPE an ideal choice for high-throughput laboratories where speed and accuracy are essential. Automation includes the use of additional equipment or robots that are programmed for specific product measurements and protocols.
Phenomenex SPE Cartridges
Cartridges, often referred to as tubes, are small, cylindrical containers filled with a specific type of SPE sorbent material used to capture, retain, and isolate target analytes from a sample. Phenomenex SPE cartridges stand out for their high performance and consistency in delivering clean, concentrated samples ready for analysis. They come in a variety of volumes, even going up to 150 mL Giga Tubes for large volume formats.
Smaller tubes are often used for limited sample volumes typically seen in clinical and pharmaceutical applications. On the other hand, larger cartridges and Giga tubes are commonly used in environmental and food applications, where higher sample volumes need to be processed.
For different sample sizes, Phenomenex offers several types of solid phase extraction cartridges, each tailored to specific sample preparation needs. Here’s an overview of some of the most popular options:
