Systea Easychem Pro Automated Discrete Analyzer

Overview

The Systea Easychem Pro is a fully automated discrete analyzer engineered for high-precision, low-volume wet-chemical analysis in environmental, clinical, food & beverage, and industrial quality control laboratories. Unlike continuous flow or flow injection systems, the Easychem Pro employs true discrete (batch-mode) analysis—where each sample and reagent are dispensed into individual cuvettes, reacted under controlled conditions, and measured statically using photometric detection. This eliminates fluidic artifacts inherent in flowing systems: no baseline drift, no carryover, no bubble interference, and no requirement for hydraulic equilibration. The system implements classical colorimetric chemistry principles—leveraging stoichiometric reactions, controlled incubation times, and endpoint or kinetic absorbance measurement—with robotic precision that replicates and surpasses manual benchtop methodology. Its architecture is purpose-built for regulatory compliance environments, supporting audit-ready operation in GLP, ISO/IEC 17025, and FDA 21 CFR Part 11–aligned workflows.

Key Features

• True discrete analysis platform: Each reaction occurs in an isolated 10-mm-pathlength quartz or optical-grade plastic cuvette, ensuring zero cross-contamination and maximal photometric reproducibility.
• Dual-mode sample handling: Configurable 60-position single carousel or 30+30 dual-carousel layout for flexible throughput and staggered batch processing.
• 30 dedicated reagent positions with integrated cooling (optional), enabling stable storage of light- and temperature-sensitive reagents (e.g., diazonium salts, enzymatic substrates).
• High-fidelity photometry: Tungsten-halogen light source (340–880 nm) coupled with precision monochromator and thermally stabilized detector—optimized for both visible and near-UV assays (e.g., nitrate, phosphate, cyanide, phenol).
• Intelligent process supervision: Real-time monitoring of liquid levels, aspiration/dispense verification, reaction temperature (via Peltier-controlled incubation block), and post-cycle cleaning validation via conductivity and optical residue checks.
• Minimal consumables architecture: No pumps, tubing, manifolds, or filters—only disposable cuvettes and pipette tips. Average reagent consumption: 3–8 µL per test, reducing cost-per-analysis by >70% versus conventional flow-based systems.

Sample Compatibility & Compliance

The Easychem Pro accommodates aqueous matrices including wastewater, drinking water, serum, urine, digestates, and food extracts without pre-filtration in most cases. It supports EPA Methods 353.2, 365.2, and ASTM D5179 for nutrient analysis; ISO 6878 for phosphate; and USP for ethanol assay. All hardware and software modules comply with IEC 61000-6-2/6-4 (EMC), CE marking requirements, and RoHS directives. Data integrity controls—including electronic signatures, full audit trail (user actions, method changes, calibration events), and immutable result archiving—meet ALCOA+ principles and facilitate GxP validation.

Software & Data Management

The proprietary ChemLab Suite provides intuitive, role-based interface navigation: technicians access pre-validated methods via one-click run queues; method developers utilize built-in scripting (TCL-based) to define multi-step protocols (e.g., dilution cascades, timed reagent additions, dual-wavelength ratioing). All data are stored in ACID-compliant SQLite databases with optional export to LIMS via ASTM E1384 or HL7 interfaces. QC management includes up to five independent control levels per assay, automatic Westgard rule evaluation, Levey-Jennings chart generation, and out-of-specification (OOS) workflow triggering.

Applications

The Easychem Pro delivers validated performance across regulated and research-driven applications: total phosphorus and orthophosphate in municipal effluent (EPA 365.3); nitrate + nitrite via cadmium reduction (EPA 353.2); chloride by mercuric thiocyanate (ISO 9297); ammonia by salicylate-hypochlorite (ISO 7150-1); alkalinity titration endpoints; and enzymatic assays (e.g., glucose oxidase, cholesterol esterase). Its static cuvette format enables reliable measurement of turbid or particulate-laden samples where flow-cell fouling would compromise FIA/CFA reliability.

FAQ

How does discrete analysis differ from flow injection or segmented flow?
Discrete analysis isolates each reaction in a dedicated cuvette—eliminating dispersion, band broadening, and memory effects common in continuous-flow systems.
Can the Easychem Pro perform kinetic assays?
Yes—programmable time-resolved measurements at user-defined intervals (e.g., 0–300 s) support enzyme kinetics, oxidation-reduction rates, and complex formation studies.
Is method transfer from manual SOPs straightforward?
Absolutely—the system replicates manual pipetting volumes, incubation durations, and mixing sequences; validation typically requires ≤3 days of comparative testing against reference methods.
What maintenance is required beyond routine cleaning?
Annual optical alignment verification and biannual syringe calibration—no pump replacements, valve servicing, or tubing changes are needed over the instrument’s service life.
Does it support remote monitoring and diagnostics?
Yes—integrated web server enables real-time status viewing, error log download, and secure remote support sessions with Systea application engineers.
