Flow Analyzers

This is the flag ship model of Astoria-Pacific’s Industrial Division. The system’s six (6) channel digital detector is ideal for laboratories (i.e. Oceanography, Tobacco, etc.) that want to test four to six parameters from a single sample. Using micro-Segmented Flow Analysis, the Astoria Analyzer follows the modular design layout: 311 XYZ Sampler, 322 Auxiliary Pump (for sampler wash), 302D Micropump (peristaltic pump), 303A Cartridge Base, with room for up to six chemistries; and 305D Digital Detector.  For the research and development of new methods, the Astoria Analyzer makes a good platform because the layout of the system makes the change-out of cartridges easier, the six channels of the 305D allow for extra channels that can be used for reference signals, and optional detectors (fluorometer, UV, and Flame) can be plugged into the system as well.

Furthermore, unlike other segmented flow analyzers (SFA), the Astoria’s analysis rates are twice as fast and only use a tenth of the reagent. In other words: a standard SFA may run at 45 samples per hour and use 450 mL of reagent, while the Astoria will run at 80 – 90 samples per hour and only use 50 mL of reagent!

Of course the savings on reagents are only a small part of what the analyzer will do for your laboratory; after all, since it uses SFA, the Astoria will attain levels of detection that are equivalent to or even lower than any other system. For instance, take a flow injection system that has a post-distillation cyanide method with a working range of 0.005 – 0.5 mg/L–although these are impressive numbers, the Astoria beats it by a factor of 10, with a working range of 0.0005 – 0.50 mg/L as CN (PN 305-A111-A01).

Additionally, the Astoria Analyzer offers a variety of techniques that have made SFA so powerful in the past, present … and future to come. For example, In-Line Dialysis, In-Line Distillation and In-Line UV Digestion are options allowing customers to quickly analyze samples that would otherwise require additional sample prep. Phenol, Cyanide and TDN are examples of methods that the lab could automate this way. Our applications team  would be happy to help you customize any chemistry.
