Ocean Research Drives Growth for SEAL Analytical

SEAL Analytical’s AA3 HR instrument used for the analysis of seawater.

Business is booming in the UK for SEAL Analytical, the manufacturer of the AA3HR and QuAAtro automated segmented flow laboratory analyzers.

Explaining the recent upturn in business, EMEA Sales Manager Haydon Warner says: “Automated testing of large numbers of samples at very low levels of analysis has been the main driver. Our team of application chemists and engineers are constantly developing innovative new features for both hardware and software, so laboratories are obviously keen to take advantage of the latest developments when buying new or replacement equipment.”

Many of the recent orders have been placed by academic and research institutions and Haydon says: “A high proportion of the new orders have come from laboratories that test marine water, which is an application in which SEAL has a very strong reputation.”

The growth in demand for seawater analysis is being driven by a need for very low level analysis of the inorganic nutrients; nitrate, nitrite, silicate and phosphate.

Haydon says: “These nutrients are important for the growth of phytoplankton, which is a major component of the biological carbon pump; a mechanism for removing atmospheric CO2. The analysis of these nutrients underpins scientific research into the factors affecting phytoplankton communities in the oceans.”

Many of the recent orders have been for the AA3 HR instrument, which is the latest generation of the original Technicon™ AutoAnalyzer II.

Importantly, this instrument can be equipped with vibration-free LED light sources, which is essential for on-ship laboratory use.

The AA3HR operates at 60 to 70 samples per hour - these high analysis rates, combined with low reagent consumption, are achieved with segmented flow; a procedure in which air bubbles are introduced at regular intervals forming unique reaction segments that are mixed using glass coils before passing through a chemistry manifold to a high resolution digital photometer.

In addition to seawater, SEAL Analytical autoanalyzers are also employed for the analysis of surface waters, wastewater, drinking water, fertilizer, plant materials, tobacco, beverages, food and animal feeds.
