TOC Analyzer

The TOC Analyzer translates raw Total Organic Carbon signals into accurate concentrations and QC-ready reports for environmental, pharmaceutical, and industrial labs. It serves analytical chemists, QA managers, and technicians performing routine TOC determinations on water, wastewater, and process streams. When to use: data review, method validation, batch reporting, or compliance auditing. Core Logic & Features: Domain capabilities include calibration-curve handling, blank correction, internal standard adjustments, unit conversions, and batch processing. Required features: input of sample signals, dilution factors, matrix type, calibration_curve_id, and acceptance criteria; outputs: calculated concentrations, QC flags, and export-ready summaries. Optional/advanced: multiple calibration curves per method, matrix-matched corrections, trend analysis, and automated report generation. Distinguishing value: EPA/ISO TOC workflow compatibility, robust data integrity checks, and seamless export to LIMS. Inputs & Outputs: Inputs include sample_id (string), dilution_factor (dimensionless), matrix_type (string), instrument_signal (numeric, e.g., peak area), calibration_curve_id (string), and units (mg/L); optional: blank_signal. Outputs include concentration (mg/L), reported_units, calibration_status (string), qc_flags (array of strings), and summary metrics such as percent_recovery and RSD. Validation: required instrument_signal and calibration_curve_id; warn on invalid dilution_factor or unknown matrix. Algorithms & Calculations: Applies C = (A - b)/m using the current calibration curve; includes optional blank subtraction and internal standard corrections; converts units as configured; computes percent_recovery, RSD for replicates, and generates QC flags. Error & Edge Cases: Handles missing inputs with defined defaults or error codes; flags non-linear calibration, high noise, missing blanks, or unsupported matrices; external data unavailability yields retry or failure flag. Industry/Region & Localization: Supports EPA and ISO TOC methods; uses standard units (mg/L) and can adapt to regional reporting templates and data exchange formats. Assumptions & Exclusions: Assumes validated instrument data and does not perform instrument control, data acquisition, or clinical diagnostics; focused on calculation integrity, traceability, and audit-ready outputs.
