From environmental mandates to pharmaceutical breakthroughs, SPE has become the cornerstone of modern sample preparation.
Walk into any modern analytical laboratory — pharmaceutical QC, environmental monitoring, food safety, forensics — and you will almost certainly find solid phase extraction (SPE) at the heart of the sample preparation workflow. That is not a coincidence. Over the past decade, SPE has grown from a specialized cleanup technique into the dominant extraction method in laboratory science, and the forces accelerating its adoption are only intensifying.
At Organomation, we work alongside scientists who depend on reliable sample preparation every day. In this article, we explore why SPE has earned its leading position, where the market is heading, and what emerging application areas are putting new demands on SPE technology.
Responsible for roughly half of all lab extraction, SPE is the primary solvent extraction technique being adopted by laboratories in 2026.
The Fundamentals: What Makes SPE So Versatile?
Solid phase extraction is a preparative liquid technique that uses a solid stationary phase — typically silica, polymeric resins, or carbon-based sorbents packed into cartridges or columns — to selectively trap analytes of interest from complex sample matrices. Once retained on the sorbent, interferences can be washed away and the target compounds eluted in a concentrated, clean fraction ready for downstream analysis.
What sets SPE apart from competing techniques is its extraordinary versatility. The same fundamental workflow can be adapted for hydrophobic small molecules, polar pesticides, charged biomolecules, metal ions, and persistent environmental contaminants like PFAS — all by swapping the sorbent chemistry. This flexibility, combined with well-established protocols and vendor support across a mature market, means laboratories can standardize on SPE as a platform and customize it per application.
The LC-MS/MS Connection: Protecting Your Most Valuable Instrument
No single factor has done more to cement SPE's importance than the explosive growth of liquid chromatography-tandem mass spectrometry (LC-MS/MS) in pharmaceutical, clinical, and environmental laboratories. Tandem mass spectrometers are extraordinarily sensitive instruments — and extraordinarily sensitive to contamination.
Matrix components such as phospholipids, salts, proteins, and co-extracted organic matter can suppress ionization, foul ion sources, and produce false positives that invalidate entire analytical runs. SPE addresses this problem directly by leveraging electrostatic, hydrophobic, and hydrogen bonding interactions to purify and pre-concentrate analytes before they ever reach the instrument. The result is cleaner chromatography, better signal-to-noise ratios, and longer instrument lifespans — all of which translate into real cost savings and better data quality.
For laboratories running high-throughput quantitative assays — therapeutic drug monitoring, environmental contaminant panels, metabolomics studies — SPE is not optional. It is the critical gatekeeper that makes the downstream analysis possible.
The Automation Wave: Doing More with Less
If the LC-MS/MS partnership explains why SPE became essential, automation explains why it is growing. Laboratory staffing pressures, increasing sample volumes, and zero-tolerance regulatory environments are forcing labs to rethink manual workflows. SPE, historically a hands-on technique, has been at the forefront of this transformation.
Online SPE Systems
Modern online SPE platforms couple extraction directly with HPLC, eliminating the offline sample preparation step entirely. In these configurations, the SPE column is integrated into the chromatographic flow path, and sample loading, washing, and elution occur automatically within the analytical run cycle. This approach dramatically reduces analyst time per sample, minimizes the risk of sample loss or contamination during transfer, and enables faster turnaround in high-throughput environments.
Multi-Channel Automated Systems
At the high-throughput end of the market, automated multi-channel SPE systems allow laboratories to process eight samples simultaneously — each channel independently controlled — with positive-pressure delivery that applies consistent, programmable flow rates across every sample. The reproducibility gains are significant: automated systems eliminate the variability introduced by individual analyst technique, which is particularly important in regulated environments where method validation requirements are strict.
Organomation partner PromoChrom Technologies offers two compelling examples of this category. The SPE-03, PromoChrom's established 8-channel workhorse, uses a patented flow-path-integration valve to control all eight channels through a single compact module — enabling parallel processing, drying the cartridge with nitrogen, solvent mixing, and automated bottle rinsing without the bulk of traditional robotic liquid handlers. The newer Presto system pushes throughput further still, with built-in continuous pumps capable of loading eight one-liter water samples in approximately 20 minutes, making it particularly well suited to large-volume environmental extractions. Both systems run fully unattended after setup, requiring only a few minutes of analyst involvement per batch.
The PFAS Mandate: A Regulatory Catalyst for SPE Innovation
Perhaps the most consequential near-term driver for SPE technology investment is the global regulatory focus on per- and polyfluoroalkyl substances, better known as PFAS or "forever chemicals." These synthetic compounds, used in everything from firefighting foam to non-stick cookware, have proven extraordinarily persistent in the environment — and increasingly, regulators are demanding that laboratories detect them at trace levels in complex matrices.
The U.S. Regulatory Picture
In April 2024, the U.S. Environmental Protection Agency issued the first nationally enforceable drinking water standards for six PFAS compounds, establishing Maximum Contaminant Levels (MCLs) as low as 4 parts per trillion for PFOA and PFOS. The rule is expected to reduce PFAS exposure for approximately 100 million Americans. Simultaneously, the EPA finalized new test methods — including Method 1633, which tests for 40 PFAS across wastewater, groundwater, soil, sediment, and fish tissue — that are already shaping laboratory practice nationwide.
While the EPA announced in May 2025 that it intends to retain MCLs for PFOA and PFOS while reconsidering standards for four additional PFAS, the fundamental demand for sensitive PFAS testing infrastructure remains strong. Compliance deadlines for PFOA and PFOS have been extended to 2031, giving water utilities time to invest in testing and treatment — and sustaining demand for high-quality analytical methods throughout that period.
What PFAS Analysis Demands of SPE
PFAS analysis at parts-per-trillion concentrations in drinking water, wastewater, soil, and food matrices is among the most demanding applications in environmental chemistry. Interference from co-extractants is severe, and background contamination from PFAS in laboratory plasticware and solvents must be meticulously controlled. Vendors have responded by developing specialized SPE media engineered specifically for PFAS capture and cleanup — including stacked cartridge designs that layer multiple sorbent chemistries to handle the full range of PFAS compound classes in a single pass. These application-specific products represent a new tier of SPE innovation driven directly by regulatory pressure.
Why more labs will continue to adopt SPE
The global SPE market continues to expand, driven by intersecting forces across pharmaceutical, environmental, food safety, and forensic laboratories. Several application trends stand out as particularly important drivers of new SPE adoption and innovation.
Pharmaceutical and Biotech Expansion
Pharmaceutical and biopharmaceutical QC represent the most mature and demanding SPE application areas. Complex biological matrices — plasma, urine, tissue homogenates — require aggressive cleanup to remove phospholipids, proteins, and endogenous interferences before LC-MS/MS quantitation. Tightening regulatory standards for drug safety and the rapid growth of biotherapeutics, including monoclonal antibodies and cell and gene therapy products, are pushing sorbent development into novel territory with hybrid mixed-mode chemistries and size-selective media gaining ground.
Environmental Monitoring Intensification
Environmental monitoring is an area of intense growth for SPE. Beyond PFAS, labs are contending with expanding panels of emerging contaminants including microplastics, endocrine disruptors, and pharmaceutical residues in surface and groundwater. Each new contaminant class brings its own matrix challenges — pH sensitivities, competing co-extractants, low log P values — that drive the development of new sorbent chemistries and method-specific SPE products.
Food Safety and Forensics
Food safety laboratories are under continuous pressure to detect lower levels of mycotoxins, veterinary drug residues, pesticides, and processing contaminants in increasingly complex matrices — grain products, dairy, beverages, seafood. Forensic toxicology, meanwhile, faces growing caseloads driven by opioid testing, workplace drug screening, and poisoning investigations, all of which rely on SPE for the sample cleanup that makes definitive LC-MS/MS confirmation possible.
Greener SPE
An emerging trend worth watching is the development of more environmentally sustainable SPE consumables. Biodegradable SPE columns designed to reduce plastic waste in single-use applications — responding to mounting pressure from green chemistry initiatives and laboratory sustainability programs. As laboratories face increasing scrutiny of their environmental footprint, sustainable alternatives to conventional plastic cartridges may gain significant traction.
