FLOW INJECTION SYSTEM Image Area ...for your most demanding throughput needs

Am quat. Ut exeraes tionse do dolore exer SI Delivering The Performance You Need The determination and monitoring of sub-ppb concentrations of mercury has always been of special importance in the field of trace metal analysis. For more than 500 years, mercury has been recognized as a poison. Today, mercury pollution is a global problem. To control the amount of mercury polluting our environment, mercury has to be monitored in all areas of modern life. This requires fast, cost-efficient and easy-to-use methods and instrumentation that permit the determination of mercury at levels as low as a few...

High throughput for improved productivity Quick glance Whether you have just a few or hundreds of mercury samples to analyze, the FIMS can improve your laboratory productivity by providing up to 2 determinations per minute. With an optional autosampler, up to 270 samples can be analyzed automatically in any desired sequence. • High sample throughput Freedom from interferences for improved accuracy • Large sampling capacity By combining the advantages of the flow-injection technique and atomic absorption detection, the FIMS provides a freedom from interferences that is unachievable by other mercury...

The flow injection principle used in the FIMS is illustrated in the diagram below. The peristaltic pumps are used to deliver the carrier and reductant streams and for waste removal. When the Fl valve is in the FILL position, the sample loop is filled with an exact volume of sample. When the valve is switched to the INJECT position, the sample is introduced into the carrier stream and trans- ported to the mixing section for reaction with SnCI2 or NaBH4. The resulting reaction mixture is then carried to a gas/liquid separator where the elemental mercury is liberated and, after passing through the...

Flexible, Easy-to-Use Design FIMS systems are designed to provide the flexibility required to meet your varying analytical needs. Some of the flexibility features include: • Independently controlled peristaltic pumps • Individually adjustable tubing pressure • Interchangeable tubing cassettes • A variety of sample loop sizes available • Modular mixing section adaptable to different applications Figure 6. Easy interchange of FIMS absorption cell. • Carrier gas adjustable from 40 to 250 mL/min Best of all, you can even use your FIMS with an AAnalyst™ atomic absorption spectrometer to determine...

Accessories Provide Limitless Flexibility Automatic amalgamation for sub-ppb detection limits While the FIMS provides exceptional mercury detection limits (i.e., < 5 ng/L), some samples and regulations require sub-ppb detection limits. By simply adding an optional computer-controlled amalgamation system, detection limits can be further reduced more than an order of magnitude. Utilizing a fine Au/Pt gauze, the amalgamation system concentrates the mercury released by the cold vapor technique of the FIMS. Following concentration, the gauze is rapidly heated and the mercury is transported to the...
