Analytical Method Development

Dynaflow can develop gas chromatography (GC) and mass spectral (GC/MS) analytical methods including extraction methods, matrix effects, GC methods, MS detection methods, and Method Detection Limit studies.

Analysis of Trace Organics in Water

Dynaflow has expertise in identifying and quantifying polar pharmaceuticals and personal-care-products (PPCP) in water and wastewater, including raw sewage influent. The Dynaflow laboratory is equipped with a Perkin Elmer Clarus 500 gas chromatograph with mass detector (GC/MS). The Clarus 500 is capable of collecting Total Ion Count (TIC) and Selected Ion Monitoring (SIR) simultaneously, which greatly enhances its utility for identifying unknown compounds and achieving low detection limits.

Treatability Studies

DynaJets® cavitating jet nozzles provide oxidation of water without requiring the addition of any chemical oxidants. Both oxidation and disinfection can be achieved at relatively low pump pressures (20-150 psi). DynaJets® require minimal retrofitting and maintenance, and no special operator training. We can provide treatability studies for oxidation or disinfection using our in-house chemical and microbiological laboratories.

Filtration and Chemical Analysis Laboratory. Dynaflow has chemical and microbiology laboratories on-site. Analytical chemistry capabilities include trace organic analysis of water and air using gas chromatography (GC/FID and GC/PID) and mass spectroscopy (GC/MS with EI/CI). Several water quality analyses are also available including, pH, Total Organic Carbon (TOC), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Phosphorus, Ammonia, Nitrate and Nitrite, Iron, Cyanide (Total and Amenable), Total Solids (TS), Total Suspended Solids (TSS), and Volatile Suspended Solids (VSS).

Dynaflow's microbiology laboratory allows us to incubate, grow and access the viability of non-pathogenic microorganisms. Microbiology capabilities include automated cell counting and viability, optical microscopes with digital photo and video capturing, Petri plate counting, ultraviolet/fluorescence counting, SDS-PAGE Electrophoresis, and incubation and grow out facilities. Standard analyses performed include trypan blue cell viability, cell counting, Total Coliforms, Fecal Coliforms, Enterococcus, Heterotrophic plate counts, algae, and zooplankton counting and viability tests.
