Build a more complete laboratory quality-control workflow with the NLE Quality Control Combo Pack, a bundle of four standalone offline HTML tools designed to help laboratories plan sampling, perform routine QC calculations, monitor analytical performance, and evaluate measurement uncertainty.
The bundle includes:
Laboratory QC Calculator
Calculate and document common QC metrics including RPD, %RSD/CV, percent recovery, LCS/LCSD, matrix spike and MS/MSD recovery, internal standard response, calibration verification, LLOQ checks, serial dilution differences, and blank evaluations.
Measurement Uncertainty Budget Manager
Build and document GUM-style measurement uncertainty budgets using Type A and Type B components, sensitivity coefficients, correlations, effective degrees of freedom, coverage factors, expanded uncertainty, and contribution analysis.
Control Chart Manager
Create and maintain laboratory QC control charts, establish statistical limits, identify warnings and out-of-control conditions, annotate events and investigations, and document ongoing analytical performance.
Random Sampling Planner
Generate randomized and reproducible sampling plans for lots, containers, locations, and other sampling units while documenting exclusions, constraints, composite groups, and sampling instructions.
Built for Practical Laboratory Workflows
Each tool runs entirely in your web browser and is delivered as a standalone HTML file. No installation, account, subscription, internet connection, or laboratory data upload is required.
Tools include configurable laboratory criteria and documentation features, along with export options such as PDF/Print, CSV, XLSX, and reusable project files where applicable.
Ideal for analytical laboratories, quality managers, laboratory supervisors, consultants, method developers, and organizations working within ISO/IEC 17025 and other laboratory quality systems.
One purchase. Four laboratory QC tools. No recurring subscription.
These tools are designed to support laboratory quality-system workflows and calculations. They do not independently establish ISO/IEC 17025 compliance, replace approved laboratory SOPs or analytical methods, or determine laboratory acceptance criteria.
