Chromloong Chromatography Information Management System (CIMS) by Acchrom-Tech

Overview

Chromloong is a purpose-built Chromatography Information Management System (CIMS) developed in-house by Acchrom-Tech, a China-based instrumentation and software manufacturer specializing in analytical laboratory infrastructure. Engineered for regulatory compliance and operational scalability, Chromloong serves as both a standalone chromatographic data management platform and an interoperable LIMS integration layer—designed specifically for high-throughput QC/QA laboratories deploying gas chromatography (GC), liquid chromatography (HPLC/UHPLC), and hyphenated techniques (e.g., GC-MS, LC-MS). The system implements a standards-aligned architecture grounded in ISO/IEC 17025, FDA 21 CFR Part 11, and EU Annex 11 principles, with native support for electronic signatures, audit trail integrity, and ALCOA+ data governance practices. Its distributed deployment model enables horizontal scaling across multi-site laboratories while maintaining centralized control over method validation, instrument connectivity, and data lifecycle management.

Key Features

• Distributed Data Architecture: Leverages clustered relational database systems (RDBMS) with synchronous multi-node replication to ensure fault-tolerant storage, zero single-point failure, and ACID-compliant transaction handling for raw chromatograms, processed results, and metadata.
• Fine-Grained Role-Based Access Control (RBAC): Offers 120+ granular permissions categorized into administrative, analytical, review, and archival domains; ships with four preconfigured roles (Analyst, Reviewer, QA Manager, System Administrator) aligned with GxP operational segregation requirements.
• Immutable Audit Trail: Implements dual-layer auditing—system-level events (login/logout, configuration changes, user role assignments) and project-level actions (peak integration edits, baseline corrections, report generation)—all cryptographically timestamped and stored within the primary database with SHA-256 hashing for tamper evidence.
• Electronic Signature Framework: Supports five-tier signature levels (including biometric-ready extensions), each requiring unique authentication factors (password + token or certificate-based challenge); signatures are embedded directly into PDF/A-2 compliant reports and validated against PKI trust chains.
• Intelligent Peak Integration Engine: Provides over ten configurable integration event types—including shoulder detection, valley-to-valley splitting, and retention time window adaptive triggering—to accommodate complex matrices in pharmaceutical stability studies, environmental residue analysis, and food safety testing.
• Cross-Project Comparative Analytics: Enables side-by-side overlay of chromatograms, retention time alignment across batches, and statistical comparison of peak area/height RSDs, tailing factors, and resolution metrics using built-in ANOVA and trend analysis modules.

Sample Compatibility & Compliance

Chromloong natively ingests native vendor file formats from Agilent ChemStation/OpenLab, Waters Empower, Thermo Chromeleon, and Shimadzu LabSolutions—without reliance on third-party conversion utilities. All imported data retain original acquisition metadata, including instrument method parameters, sequence tables, and detector calibration logs. The system has been validated per ICH Q2(R2) guidelines for analytical procedure verification and supports full traceability from raw injection to final COA issuance. It meets the technical controls required for GLP and GMP environments, including mandatory features such as audit trail review capability, electronic record retention policies (configurable up to 30 years), and periodic integrity verification routines compliant with NIST SP 800-53 Rev. 5 IA-7 and RA-5 controls.

Software & Data Management

• Method Library Architecture: Features a hierarchical method repository supporting three distinct tiers: pre-validated reference methods (e.g., USP <621>, EP 2.2.46), internal SOP-mapped templates, and user-defined custom protocols—all version-controlled with change history, author attribution, and approval workflow routing.
• Backup & Recovery Flexibility: Delivers three recovery modes: per-project snapshot export (ZIP + XML manifest), scheduled incremental backups (with compression and AES-256 encryption), and full database image restoration via point-in-time recovery (PITR) using WAL-based PostgreSQL or Oracle RMAN integration.
• Report Templating Engine: Uses a drag-and-drop WYSIWYG editor with dynamic field binding to result sets, conditional formatting rules, and embedded scripting (JavaScript-based logic blocks) for automated pass/fail flagging, specification deviation alerts, and regulatory footnote insertion.
• API & Interoperability: Exposes RESTful APIs conforming to OpenAPI 3.0 specifications for integration with enterprise ERP (SAP, Oracle), ELN platforms, and external dashboards; supports HL7 v2.x and ASTM E1384 message exchange for clinical lab environments.

Applications

Chromloong is deployed across regulated sectors where chromatographic data integrity is mission-critical: pharmaceutical R&D and manufacturing (supporting ICH M4 CTD submissions), contract research organizations (CROs) performing bioanalytical method transfers, environmental testing labs accredited to ISO/IEC 17025:2017, and food & beverage quality centers implementing FSMA 21 CFR Part 117 traceability mandates. Its modular design allows phased implementation—from standalone CDS upgrade replacing legacy vendor software, to full LIMS-CDS convergence enabling end-to-end sample-to-report workflows with chain-of-custody tracking, instrument calibration scheduling, and CAPA linkage.

FAQ

Does Chromloong support 21 CFR Part 11 compliance out of the box?
Yes—electronic signatures, audit trail immutability, system validation documentation packages, and role-based access enforcement are enabled by default and configurable during initial setup.
Can Chromloong integrate with existing LIMS or ERP systems?
Yes—via documented REST APIs, database-level triggers, or flat-file exchange protocols (CSV/XML/JSON) with configurable field mapping and error-handling hooks.
Is vendor-specific instrument driver development required?
No—Chromloong includes certified drivers for major GC/HPLC vendors; custom drivers can be commissioned under Acchrom-Tech’s OEM partnership program.
What database platforms does Chromloong support?
PostgreSQL (recommended), Microsoft SQL Server, and Oracle Database—with automatic schema migration tools included for version upgrades.
How is software validation supported for regulated users?
Acchrom-Tech provides IQ/OQ protocol templates, traceability matrices, and UAT test scripts aligned with GAMP 5 categories; on-site validation support is available under annual service agreements.
