Tetra Empower Agent

The Tetra Empower Agent is a high-performance, Microsoft Windows-based solution built on the Empower 3 Toolkit to extract data from Waters Empower 3. Based on Injection, data is converted to JSON format and uploaded to the TetraScience Data Lake through a Data Connector.

You can query the Empower Data from the Tetra Data Lake by using the /searchEql API and Amazon Athena service. You can also view and analyze data using downstream Analytics such as Spotfire, Tableau, PowerBI, Qlik, and Jupyter Notebook.

Tetra Empower Agent Features

FeatureDescription
Complete data for an InjectionThe Tetra Empower Agent extracts the raw data based on a single injection. Data related to the Injection is outputted combined with: Sample Set, Instrument Method, Processing Method, Channel, Result, Custom Fields, and Chromatography data (2D/3D), and so on.
Auto-detect Injection changeNew Injection or Injection change can be automatically detected. The Tetra Empower Agent will regenerate a new version of the RAW file if the underlying injection is changed.

To detect the Injection change, you should enable the Empower Full Audit Trail option and the Empower user used to run the agent must have permission to access audit trail for the project(s).
Result Sign-offProvides option to include or exclude Injection with or without the result being signed off.
High-performanceOn average, it takes 1.2 seconds to generate one Injection RAW file.
Low impact on existing Empower System and UsersThe Tetra Empower Agent does not change any data in the Empower system.

When the Tetra Empower Agent is up and running, there is little overhead to the Empower Server and no performance impact to other users using Empower at the same time.
Flexible to select projects from EmpowerThe Tetra Empower Agent provides a similar user interface to navigate projects using a parent-child hierarchy.

You can select projects to extract by simply clicking the checkboxes.
Resilience and transient fault handlingProvides retry policies to apply in case of any errors from Empower, hardware, software, or the network. The retry count is configurable.
RobustnessHandles undocumented Empower ToolKit and Native C++ errors.
RecoverableThe SQLite database is backed up to the Data Platform daily. If the Agent host server crashes, you can easily migrate the data to a different server without losing any progress.
Full Application Audit LogThe Tetra Empower Agent generates full operation log logs for auditing.
Supports connection options to the TetraScience Data PlatformYou can deploy the Tetra Empower Agent in two ways: On-Premises by using a Tetra Hub, or by using the TDP (No Connector) option, which allows the Agent to upload source data directly to the TDP or Amazon Simple Storage Service (Amazon S3). Both options support S3 Direct file upload for large RAW files (larger than 500 MB). For more information, see Agent Deployoment Options.
