# Automated sample preparation for analytics Automated solid-phase extraction, robotic autosamplers and GC/LC-MS sample-introduction platforms that replace manual extraction, cleanup and injection steps ahead of analytical instrumentation — the front-end automation layer distinct from general liquid handling and nucleic-acid extraction robots. Source: https://en.bioecon.ru/technology/automated-sample-prep-analytics/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: US FDA GMP analytical method validation + EPA method-specific sample extraction guidance | OECD: Industrial biotechnology | Regulator: FDA (USA), EPA (USA), REACH framework (EU)] Automated sample preparation for analytics covers the instruments that extract, clean up and introduce a sample ahead of an analytical instrument — chromatography, mass spectrometry or GC-MS — rather than the general-purpose liquid handlers that move fluids between microplate wells or the nucleic-acid extraction robots that purify DNA/RNA. A modern automated solid-phase extraction (SPE) system runs a full extraction and cleanup protocol on a batch of samples unattended, replacing a manual bench process with a walk-away run, while a robotic autosampler introduces prepared samples into a GC or LC system on a fixed schedule without an operator present overnight. The category spans environmental and food-safety extraction workflows (PFAS, pesticide residue testing under EPA method guidance), pharmaceutical QC sample cleanup ahead of HPLC/MS analysis, and GC/GC-MS sample introduction for volatile and semi-volatile compound analysis. Because this front-end automation is purpose-built around a specific analytical workflow rather than general-purpose plate-to-plate liquid transfer, its vendor base and product lines are largely distinct from the broader lab-automation and liquid-handling platforms that serve genomics and synthetic-biology screening. The key directions of automated sample preparation for analytics are: 1. **Automated solid-phase extraction (SPE):** unattended extraction and cleanup systems run a full SPE protocol on a batch of samples, replacing manual bench extraction with a walk-away run for environmental, food-safety and pharmaceutical sample prep. 2. **Robotic autosamplers for GC/LC introduction:** autosamplers introduce prepared samples into a gas or liquid chromatograph on a fixed schedule, widely used across chemical analysis, pharmaceutical and environmental testing fields. 3. **GC/GC-MS sample-introduction automation:** dedicated multipurpose samplers extend beyond simple injection to headspace, SPME and thermal desorption sample-introduction modes for volatile and semi-volatile compound analysis. 4. **Method-specific automated extraction and cleanup:** vendor-published application protocols automate extraction and cleanup for regulated methods (e.g., EPA 1633 PFAS testing), reducing method-to-method revalidation effort. ### Sectoral value chain ``` [Raw sample] ──> [Automated extraction/cleanup] ──> [Prepared sample] │ (autosampler introduction) │ ▼ [Analytical result] <─── [Chromatograph / MS instrument] <─── [Sample introduction] ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Instrument manufacturing** | Automated SPE systems, autosamplers and multipurpose samplers are manufactured to a defined analytical-workflow specification. | **In:** instrument components. **Out:** manufactured sample-prep instrument. | | **Method development** | Vendor or user-developed protocols define the extraction, cleanup and introduction steps for a specific analytical method. | **In:** target analyte method requirements. **Out:** validated automation protocol. | | **Unattended extraction and cleanup** | The instrument runs a full extraction/cleanup batch on a set of samples without operator intervention. | **In:** raw samples, method protocol. **Out:** prepared, cleaned-up samples. | | **Sample introduction** | A robotic autosampler introduces prepared samples into the analytical instrument on a fixed schedule. | **In:** prepared samples. **Out:** instrument-ready sample injection. | | **Analytical measurement** | The chromatograph or mass spectrometer measures the introduced sample. | **In:** introduced sample. **Out:** raw analytical signal. | | **Result reporting and method compliance documentation** | Results are compiled and documented against the validated method for regulatory or QC compliance. | **In:** raw analytical signal. **Out:** compliance-documented analytical result. | Cross-cutting technologies of the sector: - **Unattended SPE batch processing:** a full extraction and cleanup protocol runs on a batch of samples without an operator present, converting a manual bench process into a walk-away automated run. - **Multi-mode sample introduction:** a single autosampler platform supports liquid injection, headspace, SPME and thermal desorption modes, extending automation beyond simple sample transfer into the introduction technique itself. - **Method-specific validated protocols:** vendor-published automation protocols for regulated methods (PFAS, pesticide residue) reduce the revalidation burden a lab faces when adopting automated sample prep for a compliance-driven analytical method. --- ## US The US hosts two global analytical-instrumentation companies with dedicated automated sample-preparation product lines addressing regulated environmental and clinical testing methods. ### regulated-method automation, clinical and environmental extraction workflows - **PerkinElmer:** the JANUS G3 liquid handling workstation is a flexible automation platform supporting high-throughput liquid handling for sample-preparation workflows across chemical analysis and pharmaceutical applications. - **Waters Corporation:** publishes dedicated application notes automating sample extraction and cleanup for regulated methods, including PFAS extraction from fish tissue following EPA 1633 guidance, alongside its broader analytical-instrumentation business. --- ## CN No China-headquartered automated sample-preparation instrument maker cleared this screening round with confirmed, on-domain evidence;
