Key Benefits

  • Regulatory-ready methods — validated ASTM and ISO cyanide methods accepted by regulators across Australia and internationally
  • High throughput — analyse 20–90 samples per hour, reducing turnaround time for large sample batches
  • Multiparameter capability — run cyanide alongside other analytes on the same platform, consolidating laboratory instrumentation
  • Lower cost per analysis — automated reagent delivery minimises waste compared to manual wet chemistry

Overview

The FS3700 (also known as Flow Solution 3700) is a continuous flow automated wet-chemistry analyser from OI Analytical. It supports both Segmented Flow Analysis (SFA) and Flow Injection Analysis (FIA) methods, enabling multiparameter analysis of water, wastewater, soils, and plant digests.

With validated cyanide methods available (ASTM D6888, OIA-1677-09, ASTM D7511), the FS3700 can be configured for both available and total cyanide determination when equipped with the appropriate chemistry cartridges and detectors.

Key Features

  • Continuous flow analysis: SFA, FIA, iSFA, and SFIA methods on different channels simultaneously
  • Validated cyanide methods available (ASTM D6888, OIA-1677-09, ASTM D7511, ISO 14403)
  • Two detector boards standard - supports photometric, amperometric, and ISE detection
  • Photometric detection: 420-880 nm with 5-, 10-, or 20-mm PEEK flow cells
  • Modular chemistry cartridges - pre-assembled and validated by OI Analytical
  • Throughput: 20-90 analyses per hour per channel (method-dependent)
  • Autosampler options: 90-position or 360-position configurations
  • FlowView software with LIMS-compatible data export
  • Multiple systems can be linked for additional concurrent channels
  • Windows-compatible (32/64-bit)

Typical Applications

  • Available and total cyanide analysis (mining, environmental)
  • Nutrient analysis: ammonia, nitrate, nitrite, phosphorus, silica, TKN
  • Drinking water and wastewater compliance monitoring
  • Agricultural soil extracts and plant tissue digests
  • Industrial process water quality control
  • Environmental research laboratories

Frequently Asked Questions

Is the FS3700 a discrete analyser?

No. The FS3700 is a continuous flow analyser supporting SFA (Segmented Flow Analysis) and FIA (Flow Injection Analysis) methods. It does not use discrete cuvettes.

What cyanide methods can the FS3700 run?

With appropriate configuration, the FS3700 supports validated methods for available cyanide (ASTM D6888, OIA-1677-09), total cyanide (ASTM D7511, ISO 14403), and post-distillation cyanide (USEPA 335.4).

What detectors are available?

The FS3700 comes standard with two detector boards supporting photometric (420-880 nm), amperometric (silver electrode), and ion-selective electrode (ISE) detection.

What is the sample throughput?

Throughput ranges from 20-90 analyses per hour per channel, depending on the method and chemistry configuration. Contact us for method-specific rates.

What autosampler options are available?

OI Analytical offers 90-position (90 samples + 9 standards) and 360-position (360 samples + 10 standards) autosampler configurations.

Can I run multiple chemistries simultaneously?

Yes. The modular design allows different flow methods (SFA, FIA, iSFA, SFIA) to run on different channels simultaneously. Multiple systems can also be linked.

What sample types can be analysed?

The FS3700 is validated for aqueous samples including drinking water, wastewater, soil extracts, and plant tissue digests.

What safety precautions are needed for cyanide analysis?

Cyanide analysis requires proper training, fume extraction, appropriate PPE, and compliant waste disposal. Always consult your laboratory safety officer and follow SDS guidance for all reagents.

Safety Note

Cyanide analysis involves hazardous reagents and samples. Proper training, ventilation, PPE, and waste disposal procedures are essential. Consult your laboratory safety officer and relevant SDS before handling cyanide materials.
