What should lab managers evaluate before purchasing an automation system?

Purchasing an automated sample preparation system is one of the most consequential decisions a lab manager will make. The right system can dramatically increase throughput, reduce analyst error, and bring a laboratory into compliance with increasingly stringent environmental regulations. The wrong choice, however, can mean months of troubleshooting, wasted reagent budgets, and workflows that never quite fit the methods they were meant to support. With laboratory automation advancing rapidly in 2026, the evaluation criteria matter more than ever.

Whether the goal is scaling up PBDE analysis automation, implementing PFAS SPE automation, or building a more sustainable extraction workflow, the questions a lab manager asks before signing a purchase order will shape laboratory performance for years. The following sections break down the five most critical factors to assess before committing to any automated sample preparation platform.

Throughput, sample volume, and matrix compatibility

The first question any lab manager should ask is straightforward: can this system handle the actual workload, not just the ideal-case scenario described in a brochure? Throughput is more nuanced than a single samples-per-run figure. It depends on how the system manages batch sequencing, whether it can run samples in parallel or only in series, and how quickly it recovers between runs.

Sample volume flexibility is equally important. A system that performs well with 10 mL cartridges may become a bottleneck when large-volume water samples enter the workflow. Evaluate whether the platform supports the full range of cartridge and disk formats relevant to your methods, including both small-volume extractions and large-volume SPE configurations. Beyond volume, matrix compatibility deserves careful scrutiny. Laboratories analyzing food, feed, soil, sewage sludge, water, and air face fundamentally different matrix challenges, and not every automated system handles that diversity without significant method adaptation.

Solvent consumption and environmental footprint

Solvent consumption is no longer just a cost consideration; it has become a regulatory and sustainability concern that lab managers must weigh explicitly. Laboratories operating under ISO 17025 or working toward green chemistry commitments are under growing pressure to demonstrate reduced environmental impact, and the choice of automation platform directly influences this.

Systems that keep organic solvent consumption below 100 mL per sample represent a meaningful step forward compared to traditional manual extraction methods. Equally significant is the elimination of highly toxic solvents such as dichloromethane, which carries occupational health risks alongside its environmental burden. When evaluating a platform, request documented solvent consumption data for the specific methods you intend to run, not just headline figures. A system that reduces solvent use on simple matrices but reverts to high volumes for complex ones offers limited real-world benefit. The environmental footprint of laboratory automation should be assessed across the full method workflow, including concentration and cleanup steps.

Cross-contamination risk and system design

Cross-contamination is one of the most serious quality risks in high-sensitivity contaminant analysis. When laboratories are measuring dioxins, PCBs, PBDEs, or PFAS at trace levels, even minor carry-over between samples can invalidate results and trigger costly reruns or regulatory non-conformances.

The fundamental design question is whether samples come into direct contact with shared system components. Platforms where samples are isolated from the instrument itself, rather than passing through shared tubing or valves, eliminate the primary contamination pathway. For PFAS analysis in particular, the materials used in the flow path matter enormously. Systems with fully inert flow paths that are free from fluoropolymers such as PTFE are essential for reliable PFAS SPE automation, since PTFE-based components can leach or retain PFAS compounds and compromise analytical integrity. Before purchasing, ask the vendor for documented carry-over data from real sample sequences, not just blank runs.

Method validation, accreditation, and regulatory fit

An automated system must fit within the regulatory and accreditation framework the laboratory operates under. For laboratories holding or pursuing ISO 17025 accreditation, any new system requires method validation before it can be used in routine analysis. Understanding the validation burden upfront prevents surprises after installation.

Regulatory fit goes beyond accreditation. Environmental contaminant analysis is governed by specific method standards, including EPA 1613B, EPA 1668A, and various CEN methods, and the automated platform must be demonstrably compatible with these frameworks. Peer-reviewed literature and published application notes from independent laboratories provide stronger evidence of regulatory fit than vendor-produced validation summaries alone. When evaluating a laboratory automation supplier, ask specifically which EPA or CEN methods have been validated on the system, and request access to published data or application notes that support those claims. A supplier who can point to peer-reviewed publications and external laboratory validations is demonstrating a level of scientific credibility that matters in regulated environments.

Vendor expertise, training, and long-term support

The quality of post-purchase support is often the difference between a system that delivers on its promise and one that becomes a source of ongoing frustration. Laboratory automation is not plug-and-play, and the complexity of environmental contaminant methods means that initial configuration, method transfer, and ongoing troubleshooting require genuine domain expertise from the supplier side.

Evaluate whether the vendor offers structured training programs, not just a user manual. Consider whether they have in-house analytical expertise in the specific contaminant classes relevant to your work, such as dioxins, PCBs, PFAS, or pesticides. A supplier who understands the chemistry, not just the hardware, is far better positioned to help when method performance issues arise. Long-term support infrastructure also matters: assess service response times, availability of spare parts, and whether the vendor can support method development and validation as your analytical scope evolves. The relationship with a laboratory automation supplier should be viewed as a long-term partnership, not a one-time transaction.
