Record
Capture both columns, LC-system volumes, flow, injection, measured source pressure, target limit, gradient rows, analyst, and method reference.
Offline HPLC transfer workspace
Gradientforge
Translate a gradient across columns and LC systems, surface dwell effects, review measured suitability, and preserve the handoff evidence.

From source method to reviewable record
Keep the transfer assumptions visible
Gradientforge treats method transfer as a documented workflow. The source system, target system, column geometry, gradient program, measured pressure, suitability observations, and operator notes remain attached to one local project.
Translate
Scale gradient time by column volume and flow, then surface dwell-delay effects, target-flow geometry, injection scaling, and solvent demand.
Review
Enter measured peaks and the controlled method's own criteria to calculate adjacent resolution, plate count, tailing, and area RSD status.
Handoff
Export readable and machine-readable evidence with a SHA-256 manifest and a local audit trail of project changes.

Make the handoff inspectable
A translated table alone does not show how it was produced. Gradientforge packages the entered configurations, calculations, findings, suitability observations, and audit state alongside a readable report.

Experimental verification required
Planning aid, not instrument control or method validation
Gradientforge uses user-entered values and simplified scaling relationships. It does not control an LC system, import proprietary instrument methods, predict chemical selectivity, prescribe acceptance criteria, qualify equipment, release a batch, validate or verify a method, or certify regulatory compliance.
Confirm chemistry, column limits, pressure, dwell behavior, system suitability, and method performance experimentally under the laboratory's controlled quality system.
