Analysis of Herbicides in Drinking Water

Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases...

Bromate analysis for the drinking water industry

Bromate forms during the ozonization of drinking water. Several international standards stipulate detection limits and test methods. Conductivity detection with chemical suppression allows the determination of bromate in the lower μg/L range. In the ng/L range, bromate can be detected by IC/MS coupling or post-column derivatization with potassium iodide and subsequent UV detection.

Data analysis and visualization tools for surface water modelling

Volumetric modeling of surface water bodies to include mapping of properties data into the volume requires the capabilities only found in EnterVol. When trying to assess the health of a lake, river or stream, volumetric data is essential. Once you apply the capabilities of EnterVol to this task, you’ll discover trends in your data that were previously hidden or suppressed by the limitations of 2D techniques.

Gas analysis & monitoring systems for water - natural sciences

In nature, the chemical elements can be represented by more isotopes, or atoms of the same element, characterized by a different number of neutrons in the nucleus. When the proton / neutron ratio does not exceed that value likely to upset the balance of the atom, resulting in the phenomenon known as stabilization of radioactive decay, the isotope is called stable. That is, over time, will not tend to emit energy and sub-nuclear particles to gain energy stability, giving rise, at the end of the process, the...

Oil in Water Analysis for Flowback or Produced Water

The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote lab results can take several days to a week. InfraCal TOG/TPH Analyzers allow for oil in water testing at the well site in less than 10 minutes. The sampling requires a few simple steps that...

RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages.
