FIAS 400 Flow Injection System

You can select from two FIAS models:

• The FIAS 100 has a single peristaltic pump for carrier, reagent and sample solutions.
• The FIAS 400 features two peristaltic pumps. Two pumps are required if the analysis calls for: two solutions to be pumped at different flow rates (on-line dilution); the addition of multiple reagents; or the use of an on-line microwave digestion technique.

In both models, a five-port valve permits flow switching and precise sampling with interchangeable sample loops. Carrier gas flow is controlled via a flowmeter display. A quartz cell with removable quartz windows is provided for FI-mercury or hydride determinations. The cell can be heated with either an air-acetylene flame or an optional temperature-regulated electrically heated cell assembly.

The FIAS systems are equipped with an RS232 interface. A supply of start-up materials and all manuals are included. A push-button device for manual program starts is supplied with the FIAS-100. Additional options for the FIAS-100/400 include the alternate reagent
