Astoria Analyzer



Astoria-Pacific Analyzers

This is the flag ship model of Astoria-Pacific’s segmented flow analyzer line. The system’s versatile 307 digital detector is ideal for laboratories (i.e. Oceanography, Tobacco, etc.) that want to test one to six parameters from a single sample. It can be configured with photometric and/or fluorometric detectors. Using micro-Segmented Flow Analysis, the Astoria Analyzer has a modular design: 411 XYZ Sampler, 302D Micropump (peristaltic pump), 303A Cartridge Base with room for up to six chemistries*, and 307 Digital Detector. (See Additional Modules for more information about these units.)

Additionally, 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 307 Detector can be configured with both photometers and fluorometers, and an optional detector (fluorometer, UV, Flame, etc.) can be plugged into the system as an additional channel.

Common tests performed on the Astoria System for Water and Wastewater analysis are:

  • Alkalinity
  • Ammonia by GAS Diffusion
  • Chloride
  • Chlorine
  • Cyanide (Post Dist.)
  • HexChrome
  • Nitrate (Cadmium)
  • Nitrite
  • Ortho-Phosphate
  • Phenol (Post Dist.)
  • Silica
  • Sulfate
  • TKN
  • T. Nitrogen (Pers.)
  • T. Phos (Pers.)
  • Silica

*NOTE: The ability to run six simultaneous analyses is dependent on matrix and analyte type.

Compared to other segmented flow analyzers (SFA), the Astoria’s analysis rates are up to 2X faster than comparable systems, and only use a tenth amount of reagent.

  • Example 1: A standard SFA may run at 45 – 50 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.

The savings on reagents are only a small part of what the analyzer will do for your laboratory. Since it uses SFA, the Astoria will attain levels of detection that are equivalent to or even lower than other systems.

  • Example 2: Compared to a flow injection system that has a post-distillation cyanide method with a working range of 0.005 – 0.5 mg/L, an Astoria Analyzer beats it by a factor of 10, with a working range of 0.0005 – 0.50 mg/L as CN (PN 305-A111-A01).

Although discrete analyzers have made a significant impact in environmental testing, the Astoria Analyzer offers a variety of techniques that have made SFA so powerful in the past, present and future to come:

  • In-Line Dialysis can remove interferences like matrix effects, utilize gas diffusion techniques for Ammonia in lieu of the distillation step, and can be used like a dilution loop
  • In-Line Distillation and In-Line UV Digestion are options allowing customers to quickly analyze Phenol, Cyanide and TDN that would otherwise require additional sample prep*

*NOTE: Consult with your regulatory agency for acceptance of these methods in your region.




Contact an Astoria-Pacific representative and ask him/her what system configuration or platform might be best for your laboratory. Whether it’s the Astoria, Astoria2 and/or rAPID-T analyzers, you won’t go wrong by entrusting us to satisfy your needs. **NOTE: The woman to the left doesn’t work here; she’s cute, but this isn’t a dating site.
