New Protocols & Techniques
HACH Frac-Water Kit
HACH Kit
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
