Gallery™ Plus Automated Photometric Analyzer, Gallery Plus - FAQs

Can I integrate discrete analysis with ion chromatography for comprehensive water analysis?

Yes. We offer Disc IC packages that pair discrete analysis with Thermo Scientific Dionex ion chromatography systems, delivering high throughput, comprehensive water/ion analysis without method changeover.

How does a discrete analyzer compare to flow analyzers (FIA/SFA/CFA)?

Compared with traditional continuous-flow systems, Gallery and Gallery Plus discrete analyzers’ random-access, discrete design with disposable cuvettes minimizes carryover, cuts reagent use (typically <100 μL per test), shortens startup/changeover times, and boosts throughput (200–350 tests/hr vs 60–120 tests/hr). Labs also report much lower cost-per-test (up to 20x) due to smaller volumes and less waste. These systems also provide more measuring channels (12 filter positions), greater method stability, and fully automated micro liquid handling, which reduce operator skill requirements and system maintenance.

What reagents and consumables are available? Can I use third party reagents?

We offer ready to use, barcoded system reagents and enzymatic kits for environmental/industrial water and food & beverage testing, these minimize prep time, consumption, and cost per analysis. The platform is also open and flexible to support third party photometric methods and reagents if needed.

What “walk away” and automation features are built in?

After loading samples and reagents, the system can run unattended for up to 3 hours. Automation features include the ability to add samples mid-cycle (for the next cycle) without disrupting current tests, automated start up/shut down, and barcode scanning/LIMS connectivity for traceability.

Can I run photometric tests and pH/conductivity at the same time?

Yes. With the optional Electrochemical Measurement (ECM) module, pH (approximately 2 to 12) and conductivity (~20 μS/cm–112 mS/cm) can be measured in parallel with standard photometric assays, enabling truly consolidated multiparameter runs. ECM throughput is up to 54 measurements/hr on Gallery systems and up to 67 measurements/hr on Gallery Plus models.

How much sample and reagent volume do tests require, and how is carryover minimized?

Gallery systems utilize disposable Thermo Scientific DECACELL cuvettes, which prevent carryover or cross-contamination and sharply reduce reagent consumption. Compared to manual or continuous-flow methods, DECACELL cuvettes require smaller sample and reagent volumes (2–240 μL).

How many parameters per sample can be measured and what optics are available?

Up to 20 parameters can be analyzed from one sample. Gallery instruments offer 12 optical filter positions and a 340–880 nm spectral range (with different filter configurations), supporting sensitive detection down to the ppb level for many analytes.

What kinds of samples and applications can I use these systems with?

Gallery systems are designed for analyzing environmental and industrial waters (drinking, ground, surface, wastewater, process water), soil/nutrient analysis, enzyme analysis, and analysis of food & beverages (e.g., wine, beer, malt, juice). The platform’s applications are aligned with US EPA, ASTM, DIN, ISO, AOAC, ASBC, OIV, and IDF methods.

What is the difference between Gallery and Gallery Plus discrete analyzers?

Both platforms share the same core workflow, but the Gallery Plus system is a larger, higher capacity model. Key differences include:

• Throughput: Gallery system performs up to 200 photometric tests/hour, Gallery Plus system performs up to 350 tests/hour.
• Sample capacity: Gallery system can handle up to 90 samples, Gallery Plus system can handle up to 108 samples.
• Reagent capacity: Gallery system has a maximum of 30 reagent positions, Gallery Plus system has up to 42 positions.
• Walk away time: Gallery system provides up to 2 hours, Gallery Plus system provides up to 3 hours.
• Water use: Gallery system uses ~1.5 L/hr, Gallery Plus system uses ~2.5 L/hr

What is a Gallery discrete analyzer and how does it work?

A Thermo Scientific Gallery discrete analyzer is an integrated, benchtop system that automates photometric tests (colorimetric and enzymatic). An optional electrochemical measurement (ECM) unit can be added to the system to perform electrochemical measurements (pH and conductivity). It uses disposable Thermo Scientific DECACELL cuvettes and automates all necessary analysis steps, including liquid handling, incubation, measurement calculations, and reporting, allowing for up to 20 analytes to be measured from the same sample with minimal carryover.
