Wet-Chemistry MethodsChloride ISE & HQ40D MeterPilot Tested ProtocolsSample Prep AdjustmentsNoted Matrix Interferences

Since Then

HACH Has the New Kit On The MarketIssues Noted in Trials Were CorrectedAdjustments to Chemistries DocumentedMethods Redesigned and Written

InnovOx

GE Analytical InnovOx SCWO

TOC/NPOCOriginally Designed for Industrial Waste Monitoring & Sewage AnalysesBrought It To The “Next-Level”First Major Field TrialResearched the Overall Method and Performance of SCWO on Produced Waters

Since Then

Modified Sparge Chamber30 New Chemistry Protocols for Produced WatersRedesigned SoftwareNewly Designed Acid Flow Ratio ValveTEEX: “Go-To” People for TOC/NPOC Analyses of Produced Waters

Hapsite GC/MS for BTEX/VOC

Inficon-HAPSITE GC/MS

First Time in Field Analyzing Produced WatersPrimarily Used in Air Quality Monitoring and Military MonitoringPreliminary Modifications Planned for Before DeploymentWhat Issues Could Arise?

Hapsite

Great First TrialAccuracy & Precision Were On-TargetNo Issues With Sample Matrix NotedSince: Working on Research and Usage Concepts

Additional Evaluation Studies

Modified Oil & Grease MethodsTPH ScanFuture Concepts of On-line analysis InstrumentsImproving Upon Existing MethodsDeveloping Specifics for Industry Clients

Isotopic Sample Kits

Radioisotope Success!

Results Very Important to Treatment Process & MonitoringBuilds Strong Database of Water Quality Not ExistingProvides Additional Understanding to Important Research and Treatment Steps

Future of Analytical Monitoring of PW

Additional R&D NeededResearch Prospects for Analytical Roundtable GroupEnhanced Scientific CollaborationsDeveloping Extensive Background Data of WatersSharing of Scientific Results
