SEAL Analytical




Food & Beverage Analysis- Recommended Instrument

For high throughput labs looking to analyse food and beverage and up to 4 or 5 chemistries, the AA3 or QuAAtro Continuous Segmented Flow Analyzers are ideal. For low to medium throughput labs looking to analyze food & beverage for multiple chemistries consider a SEAL AQ Discrete Analyzer. Please contact us to discuss your laboratory's requirements

Continuous Segmented Flow Analyzers
For over 50 years SEAL Analytical (previously Bran+Luebbe/ Technicon) has been the expert in automated wet chemistry analyzers and sample preparation instruments. We understand that regulated standard methods are critical, so all SEAL analyzers are supplied with detailed method descriptions including reagent make up, flow diagrams and specific application notes.

Analyzers Suitable for Food & Beverage

  • AutoAnalyzer 100 (AA100)- Ideal for laboratories running 1 or 2 dedicated chemistries. Compact benchtop analyzer.
  • AutoAnalyzer 3 HR (AA3 HR) - Up to 100 samples/ hour. Future proof modular design. 
  • QuAAtro- A microflow analyzer ideal for labs requiring high speed & high throughput analysis, with ultra-low detection limits.

Food & Beverage Analyzer Methods

  • SEAL Analytical has an extensive library of over 1000 methods.
  • Multi-range methods, giving the ability to set up your desired range.
  • Dialyzers are sometimes used to stop any color interference and/or dilution.
  • Methods used with older AutoAnalyzer II and TrAAcs systems are completely transferable to current model AutoAnalyzers.

Typical Food & Beverage Parameters

Reducing Sugars in Wine
Volatile Acidity in Wine
Amylose in Rice Extracts
Hydroxyproline in Meat & Meat Products
Nitrate & Nitrite in Meat & Food Extracts
Nitrate in Milk
Sulfur Dioxide in Beer
Reducing Sugars
Starch in Tobacco, Plant & Food Extracts

Sample Preparation

Methods are available of all common sample preparation procedures.

For automated Kjeldahl digesttions use a Hot Block Digestion System (BD28 & BD50).



Discrete Analyzer
The compact Discrete Analysers can be an option for some applications. SEAL Discrete Analyzers are supported by a large library of methods that include analyses important in food & beverage analysis. Our stated detection limits will be achieved by typical laboratories, with many users exceeding these detection limits.

Discrete Analyzer Models

  • AQ1 Discrete Analyzer- Up to 60 tests/ hour. Up to 7 tests on a single sample. Compact bench-top analyzer.
  • AQ2 Discrete Analyzer- Up to 180 tests/ hour. Up to 7 tests on a single sample. Compact bench-top analyzer.
  • AQ400 Discrete Analyzer- High capacity analyzer. Up to 216 tests in one run. 20 cooled reagents, 6 non-cooled. Up to 30% lower detection limits.
