Feb 1, 2025February 2025 focused on delivering automation-forward enhancements to syringe and gas handling workflows in the hela o async repository, spanning CCSI, CSIL, and ADSS experiments. Key deliveries include backlash-compensated syringe refill cleanups with v3-compatible infusion logic, water injection capability with documentation and configurable volumes, syringe pump hardware reconfiguration with tuned volumes/rates, expanded gas handling including GasSample support and unloading controls, and a temporary manual phosphoric acid injection path with interrupt support and renamed gas unloading functions for clarity. Documentation updates accompanied the water-injection changes. These updates improve automation, reproducibility, safety, and throughput, while reducing manual intervention and setup time, and align with the ongoing migration to v3 logic.

Jan 1, 2025January 2025 monthly performance for High-Throughput-Experimentation/helao-async focused on reliability, automation, and hardware stability. Key sequence enhancements and new capabilities were delivered, enabling more robust experimentation and reduced manual intervention. Improvements include refactoring and refining ADSS_PA_CV_TRI and ADSS_PA_CV_TRI_new sequences with explicit injector parameter definitions, improved parameter handling, and washmod initialization fixes to ensure correct sequence processing. A new PAL injector deep-clean capability was added (ADSS_sub_PAL_deep_clean) with updated default behavior and versioning to reflect deep-clean support. Tray-to-tray liquid transfer automation was implemented in the ADSS module, enabling automated transfers between vials with configurable volume and rinsing. Finally, the server configuration was rolled back to gamry_server2 with re-enabled parameters to restore a known-good hardware/software configuration. These changes collectively improve throughput, reproducibility, and safety, while reducing manual steps and operator risk. Technologies and skills demonstrated include sequence refactoring, hardware integration (PAL injector), experiment automation, versioning, and configuration management.
