2. November 1, 19992 15915 So. San Pedro St. Gardena, CA 90248 (310) 515-2866 Standard Products Autoplex ® Double Block and Bleed, Sample Stream Select Valves Modular Sample System Manifolds Flow Switches Micro Flow Switch Flow Fuse ® Excess Flow Shut-Off Valves

3. November 1, 19993 Process Sample Systems All extractive process analyzers require sample Samples often are incompatible with analyzer Samples must therefore be “conditioned”

4. November 1, 19994 Sample System - Typical Components Filter Pressure Regulator Pressure Gauge, Transducer, Transmitter Shut-Off Valves Selector valves Relief valves Flow Meter or Flow Switch Flow Control Valve Process Sample Heating Element

5. November 1, 19995 Advanced Modular Sample System (AMSS)

6. November 1, 19996 AMSS Construction Components mounted on common base plate Base plate internally ported Each mounting “footprint’ identical Every position interchangeable Base plate available in any number of positions Multiple or optional internal porting paths Multiple manifolds can be bridged

7. November 1, 19997 AMSS Key Features Miniaturization - 1/10 Volume Internal volume minimized Eliminates contamination reduction caused by pipe and tube fittings Elimination of leak paths caused by pipe and tube fittings Enhanced servicing and maintenance

8. November 1, 19998 AMSS Design Features Standardization Defined dimensional interface Defined performance and test specifications Rapid design and development –Highly flexible design features –Rapid layout and prototype –Rapid revisions during development

9. November 1, 19999 AMSS Smart / Redundant Systems Faults detected to the system or component level Capable of automatic switching to a parallel, redundant system
