Patented Tracer-QC™ Technology

The biggest challenge with automation of radio-pharmaceutical QC is that it requires a set of very different tests which rely on conceptually different pieces of equipment or individual manual procedures. Trace-Ability has solved this challenge by focusing on the answers the tests need to provide.  Rather than developing new tools to carry out known tests, we have developed new tests that can be run on a single known tool and yield the needed answers.  The tool is a plate reader, all tests are based on assays that yield optical signals measurable by the plate reader.


Tracer-QC system consists of a plate reader with a pipetting robot on top.  It is enabled by innovative consumable kits.  The user installs the kit into the instrument and delivers a single PET tracer sample in a shielded vial.  The pipettor then mixes this sample and standards with indicators and moves the resulting mixtures to the analysis plate inside the plate reader to measure optical signals that are generated by interactions of the sample with either indicators or features of the analysis plate. The signals are interpreted as measurements of all required QC parameters and complied into a comprehensive report by 21 CFR Part 11-compliant software.  Once the process is over, the kit can be removed and the system is ready for the next procedure because the sample or reagents never come in contact with the plate reader.

Tracer-QC rHPLC configuration include a completely integrated HPLC, which is operated in an automated manner.  Tracer-QC robot performs injections of sample and standards and Tracer-QC software analyzes the chromatograms to yield the desired QC measurements.

Tracer-QC allows complete hands-free operation from a single sample to a full QC report.

Tracer-QC instrument is shielded while the sample is delivered via a keyed pig.  Thus, the operator never handles or has a direct line of sight with an unshielded sample.

The process

1. Install the kit

User scans the QR code on the kit to load the correct analysis program and installs the consumables from Tracer-QC kit onto the Tracer-QC instrument.

Tracer-QC confirms that the kit was installed properly, executes automated self-checks and indicates that it is ready to receive the sample.

Tracer-QC robot mixes the sample with indicators and dispenses the mixtures into the analysis plate. The plate reader analyses the optical signals (absorbed or emitted light) in the analysis plate.

2. Deliver the sample

The sample vial provided in the kit is placed inside a special pig that provides shielding and is designed to mate to Tracer-QC.  QC sample is added to the vial in the pig from a QC syringe inside a hot cell. The pig is then carried to Tracer-QC and placed on the deck behind shielding where it is accessible by the pipetting robot.

3. Initiate the analysis

User initiates the analysis using the software

Tracer-QC robot mixes the sample with indicators and dispenses the mixtures into the analysis plate. The plate reader analyses the optical signals (absorbed or emitted light) in the analysis plate.


The software then analyses their optical characteristics against a set of predefined and validated reference specifications and translates them into the required QC measurements.

4. Collect the report

A single page summary is delivered automatically with all QC values and pass/fail determination supported by a detailed 26-page report with all measurements of sample and standard obtained during the process as well as suitability test data.
