Continuous flow analyzer has so many applications

When American biochemist Leonard Skeggs first licensed his “AutoAnalyzer” invention for commercial production in the 1950s, the continuous flow analyzer was used almost exclusively in clinical and medical laboratories. The product was an innovation, significantly reducing the time it took to process large numbers of laboratory samples.

Skip forward half a century, and modern continuous flow analyzers — such as Astoria-Pacific’s highly respected Astoria2 analyzer, available from White Horse Scientific — now see practical, everyday use in a surprisingly wide variety of industries and research fields. In many applications with a high sample load, the Astoria 2 offers a highly efficient alternative to manual sample handling.

Water testing applications represent a common use of the continuous flow analyzer, including both wastewater treatment and the analysis of drinking water. Delivering straightforward, efficient analysis of typically up to 90 samples per hour, the Astoria2 can analyse for ion and nutrient content, iron and silica (for example for boiler water), phenol or cyanide (in industrial effluent) and many other substances.

In the agricultural industry, the Astoria2 analyzer can help measure important nutrient and ion levels in water, soil and plant feed/silage, directly helping to maximise crop yields. Offering highly cost effective and rapid sample analysis, the continuous flow analyzer can typically test levels of ammonia, nitrate, nitrite, orthophosphate, total phosphorous etc. at rates between 45 and 120 samples per hour.

Astoria-Pacific’s product heritage it built upon a system developed originally by an oceanographer, and the Astoria2 product is still perfectly suited to applications in that field, including seawater and estuary water laboratories. Boasting extremely low reagent consumption, the Astoria2 utilises “micro-segmented flow analysis” (µ-SFA) to deliver efficient low-level discovery of samples by photometric and fluorometric detection.

The Astoria2 has also seen use in the wine production industry. The extremely high volumes of bottles produced by the average winery demand high-throughput analysis methods to sample sulphite levels, volatile acidity, and so on. The efficiency benefits delivered by the continuous flow analyzer allow these tests to be completed automatically at a rate that can easily keep up with the demands of high volume production, and the accurate results provided by the Astoria2 also help ensure product quality.

Seeing similar use in breweries, and in other fields as diverse as the pharmaceutical industry and environmental / geological testing, the Astoria2 is a simple but powerful continuous flow analyzer that displays amazing versatility.
