21 CFR Part 11 Dissolution Software: Data Integrity

A dissolution result is defensible only when the laboratory can reconstruct how it was generated. The final percentage dissolved must connect to the sample, approved method, instrument conditions, analytical data, calculations, and review history.

At Raytor, we assess dissolution equipment and software as a coupled system. 21 CFR Part 11 Dissolution Software helps make up a system that ensures data integrity through controlled access, traceable changes, protected records, and accountable approvals. It is a complicated system which relies on the installed configuration, validation, and the procedures of the laboratory, as well as the compliance label.

What Records Must Be Controlled?

21 CFR Part 11 Dissolution Software is an industry term, not a separate FDA software classification. Part 11 applies to qualifying electronic records maintained or submitted under FDA requirements; it does not prescribe a dissolution method. FDA Part 11 Scope and Application

A dissolution record package should capture the information needed to reconstruct the test:

•Method: Version, apparatus, medium, volume, speed, and sampling schedule.

•Execution: Batch and vessel identities, timestamps, recorded conditions, and interruptions.

•Analysis: Original signals, standards, dilution factors, calculations, and processing history.

•Review: Audit trails, deviations, signatures, and approved reports.

A PDF report alone may not preserve the dynamic records and metadata needed for meaningful review. FDA's data-integrity guidance addresses these distinctions. FDA Data Integrity Guidance

Data Risks, Software Controls, and Verification

The value of 21 CFR Part 11 Dissolution Software becomes clearer when each feature is tested against a specific failure.

Failure Scenario	Control to Evaluate	Practical Verification
Analyst changes an approved method	Permissions and version control	Attempt an unauthorized edit
Dilution factor changes after processing	Audit trail and retained calculation history	Retrieve original and revised results
Failed run disappears from review	Complete record retention	Retrieve an interrupted run
Approval cannot be attributed	Unique identity and record-linked signature	Inspect signer, timestamp, and meaning
Interface assigns data to the wrong vessel	Validated sample mapping	Trace a known sample end to end
Archived results cannot be opened	Retention and recovery controls	Restore and review an older dataset

Audit Trails: Reviewable Evidence, Not Just Logs

An audit trail should preserve who performed an action, when it occurred, and what changed without obscuring previous information. For laboratory review, changes to methods, processing parameters, or result status deserve particular attention.

Additionally, procedures need to cover:

•The reasons for significant changes.

•Tests that have been interrupted, repeated or invalidated.

•Privileged administrator actions.

•The escalation of unexplained events.

Recording an event does not resolve it. Reviewers must consider the effect of the event on the result reported.

Electronic Signatures: Accountability Beyond Login

Access permissions control what a user can do. Electronic signatures can indicate responsibility for a record or a decision.

Signatures must display the signer's name, signing date/time, and meaning, and remain linked to the corresponding record. A shared account or pasted signature image does not provide equivalent accountability. 21 CFR Part 11

Why Dissolution Calculations Need Specific Validation

21 CFR Part 11 Dissolution Software must be evaluated beyond passwords and signatures. A fully traceable result can still be scientifically incorrect.

Consider repeated sampling: removing medium also removes dissolved drug. Depending on whether medium is replaced, the approved calculation must account for previously withdrawn drug and the applicable vessel volume.

Validation should test:

•Sampling corrections: Replacement versus non-replacement workflows.

•Dilution factors: Manual entries vs. automated dilution settings.

•Timing: Scheduled versus actual sampling and transfer delays.

•Analytical processing: Calibration and blank correction; units of measurement.

•Reporting: Rounding of results; acceptance logic at the vessel level.

Automated acquisition minimizes transcription errors, but can not validate all configurations. Interfaces must be tested to fail in order to assess ESD data problems (missing, duplicated, delayed, or misassigned).

Raytor Design Choices and Technical Implications

Our dissolution range provides different approaches to test execution and sample handling. Selecting 21 CFR Part 11 Dissolution Software should follow the required method and data path.

Raytor Model	Published Design Feature	Application Consideration
RT600	Covered vessels and synchronous dosing	Evaporation control and consistent test initiation
RT612	Individual temperature and real-time parameter monitoring	Visibility of operating conditions
RT600-ST	Anti-adsorption tubing, filtration options, optional online dilution	Recovery, filter suitability, and dilution verification
RT600-UV	Separate vessel flow paths and flow-cell pathlength options	Carryover assessment and analytical range selection

Our product page identifies Part 11 support for RT600-UV analysis software and describes dissolution accessories and customization services. Exact permissions, signatures, interfaces, and validation documentation should be confirmed for the proposed configuration. Hardware features support measurement quality; they do not independently establish electronic-record compliance. Raytor Dissolution Systems

Software Capability vs. Laboratory Compliance

Implementing 21 CFR Part 11 Dissolution Software requires documented controls around the technology.

Software Capability	Laboratory Obligation
User roles	Authorized assignment and periodic access review
Audit trails	Defined review responsibilities and investigations
Backup functions	Recovery testing and retention procedures
Configurable calculations	Approved requirements and challenge tests
Software updates	Change assessment and regression testing

Before purchase, confirm USP apparatus, throughput, sampling approach, and UV/HPLC/LIMS compatibility where required. Then link user requirements to risk-based tests, including appropriate IQ/OQ/PQ activities. Supplier documentation supports—not replaces—verification of intended use.
