Agilent Drivers for Thermo Scientific Chromeleon 7 - Release Notes – Revision 3.2

Agilent Drivers for Thermo Scientific Chromeleon 7 — Release Notes Summary (Revision 3.2)

Significance of the topic

Chromeleon is a widely used chromatography data system (CDS) in regulated and high-throughput laboratories. Agilent's drivers enable integration of Agilent LC, GC and headspace (HS) instruments into Thermo Scientific Chromeleon 7, allowing unified method authoring, sequence control and data acquisition. Reliable driver releases matter for instrument interoperability, laboratory automation, regulatory traceability, and minimizing downtime during upgrades and validation activities.

Study goals and document overview

• Present new features, hardware and firmware support, interoperability and compatibility constraints for Agilent Drivers for Chromeleon 7 Revision 3.2.
• Document installation prerequisites, verification tools (SVT), known issues and limitations, resolved defects, and the list of supported Agilent modules and minimum firmware versions.

Used instrumentation

• New or enhanced support for LC modules including 1290/1290 II/III pumps, detectors, samplers and accessories: notably G7123B (1290 Infinity III Fluorescence Detector), G7137B (1290 Infinity III Bio Hybrid Sampler), G7178A InfinityLab Assist (G7180A Assist Hub, G7179A Assist Interface), and G7175A InfinityLab Level Sensing.
• Expanded GC support including second-generation 8850 GC, broad array of Agilent GC models (Intuvo 9000, 8890, 8860, 8850, 7890 series, 7820, 6850/6890 families), many inlet and detector types, and headspace samplers (7697A, 8697 and variants).
• Support for CTC PAL3 Series II samplers (on Agilent firmware) and selected third-party modules: Thermo Fisher Corona Veo charged aerosol detector and WPS-3000 sampler with functional limitations.
• Extensive tabulated lists in the release note provide minimum required firmware for each supported module and driver component versions.

Methodology and software components

• Driver package composed of Instrument Control Framework (ICF) and dedicated LC, GC, HS, ELSD and PAL drivers. Component versions in this release include ICF 3.5, LC/CE driver 3.11, GC driver 4.4 SR1, HS driver 4.4, and SVT 6.3.4.1. ELSD and PAL drivers retained prior versions (ELSD 1.8.61, PAL 3.0).
• Compatibility guarantees target Chromeleon 7.2.10 MUf and higher including 7.3/7.4 series and later maintenance updates. Supported host OS are various 64-bit Windows Server and Windows 10/11 releases. Required .NET Framework 4.7.2+ (and .NET 3.5 for ELSD).
• Agilent Software Verification Tool (SVT) is delivered with the package to verify correct installation and generate reports. Silent install and SVT automation options are documented for unattended deployments.

Main changes and enhancements

• LC enhancements: full integration of InfinityLab Assist Hub; Steady Inject support for Multisamplers with Multiwash; hardware and software support for InfinityLab Level Sensing; pressure-controlled ramping outside analytical runs; improved injector workflow editing plus import/export; Multisampler drawer automation (with events and command-tree support); barcode confirmation workflow for LC when the G4756A Sample Reader Upgrade is present.
• GC & HS enhancements: dual manual injections for simultaneous front/back manual injections; support for PAL3 Series II samplers with advanced sample preparation workflows for GC integration.
• New generic command: GenSendCommand with GenCommandResult and GenCommandEvent properties enabling pass-through command execution against LC drivers and enabling automation scenarios like drawer control.
• Operational features: dual-injection timeout to avoid indefinite waits, ability to assign remote injectors for parallel sequence starts, and ePanel added for G7123B fluorescence detector.
• Infrastructure changes and a set of defect fixes improving stability and interoperability.

Compatibility and interoperability

• Client/server interoperability supported with constraint that client driver version must be greater-or-equal to instrument controller version; new hardware/features require synchronized versions on both client and instrument controller.
• ELSD driver interoperability is not supported; interoperability should be minimized to avoid unexpected behavior.
• Lab Advisor (Agilent diagnostic tool) can coexist; some module firmware limits controller counts and exclusivity—only one controller on certain legacy main modules.

Installation and verification

• Install using local Windows administrator account. SVT must be installed prior to the driver package. The driver requires specific firewall ports for instrument communication; the installer will create inbound rules but enterprise firewalls must allow the specified ports.
• Silent installation supported via msiexec and silent SVT execution options documented. Chromeleon IQ integrates and documents the installed driver versions as part of the IQ process.

Major known issues and limitations

• Functional limitations: no support for fraction collection modules, limited diagnostic/maintenance access (use Agilent Lab Advisor for diagnostics), CE–MS coupling not supported, certain detector types (e.g., LIF/CCD) unsupported for CE, and AD-hoc handheld controller runs not collected.
• Behavioral differences vs native Thermo instruments: Hold/Continue/StopFlow commands behave differently and should not be used; missing vial handling differs and requires configuration; Windows scaling other than 100% may truncate UI.
• GC/HS specifics: no support for retention time locking (RTL), blank run evaluation, Intuvo maintenance functions inside CDS, or high data rates (1000 Hz for 7890). Headspace sequence line limits (7697A: ≤111 lines; 8697: ≤48 lines) exist to avoid high CPU usage. PAL3 scripts manager and barcode reader not supported in this release.
• Third-party module constraints: WPS-3000 must be sole sampler, no overlapping injections, limited synchronization with pump, and other functional restrictions.

Key resolved issues

• Multiple defects fixed including incorrect audit-trail entries when removing vial trays, method editor crashes when ELSD is present, incorrect storage of FLD spectral data, and dual-injection configuration issues on some GC hardware.
• Release notes include a table of resolved issue identifiers for traceability.

Supported modules and firmware

• Detailed tables list supported LC pumps, samplers, detectors, column compartments, valves, other modules, combined LC systems, capillary electrophoresis modules and many GC models and accessories with minimum required firmware and minimum driver version. Not all fraction collectors and some advanced modules are supported.
• Users must check the release note tables for module-specific firmware minima before deployment; mismatches can require method or configuration updates after upgrade.

Practical benefits and applications

• Tighter integration of InfinityLab Assist and drawer automation supports higher degrees of sample handling automation and reduces manual interventions for high-throughput LC workflows.
• Generic command support and remote injector assignment enable custom automation and external triggers (e.g., front-panel start) for parallel workflows.
• Broad device coverage enables consolidation of instrument control within Chromeleon 7, simplifying method management and audit compliance in regulated environments.

Future trends and opportunities

• Further convergence of instrument diagnostics and maintenance into the CDS or tighter, certified co-operation with diagnostic suites (e.g., Lab Advisor) would improve single-pane-of-glass maintenance workflows.
• Expanded support for fraction collectors, advanced 2D-LC and method-scouting tools would benefit purification and method-development labs.
• Improvements to interoperability (reducing the need for synchronized versions) and enhanced third-party module compatibility will simplify rolling upgrades in large instrument fleets.
• Enhanced remote and programmatic control (more generic command coverage, improved API/events) will enable advanced automation, LIMS integration, and laboratory orchestration in regulated environments.

Conclusions

• Revision 3.2 advances Agilent Drivers for Chromeleon 7 primarily by adding support for InfinityLab Assist and new Infinity III LC modules, extending PAL3 Series II support, and introducing new automation-focused commands and ePanels. The release improves operational flexibility for automated LC workflows and expands GC/HS device compatibility.
• Careful attention to firmware minima, Chromeleon and driver version alignment, firewall configuration and SVT verification is essential to achieve stable deployment and to meet validation requirements in regulated labs.
