The investigation of compositional and structural characteristics of natural marine organic matter: a review
The natural marine Organic Matter (OM) is a complex mixture of carbohydrates, lipids and proteins present in seawater and sediments, able to affect many processes occurring in the marine environment such as the biochemical cycles of marine nutrients and living organisms. As the complexity of environmental studies concerning OM composition requires the application of accurate analytical methods, ...

Monitoring once through cooling water - Case study
The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil. These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling ...

When Consumables Kits are Greater Than the Sum of their Parts
ProteinWorks and GlycoWorks kits address more than sample prep challenges One of the most challenging parts of an LC-MS workflow happens before analytical chemists even turn to their instrument: Sample preparation. Get it right, and the analytical run performs as expected. Get it wrong, and the assay has any number of problems, from poor sensitivity to poor reproducibility. The challenges of ...

TIMS or MC-ICP-MS – which do i need?
So, you have a need for precise isotope ratio measurement of solids, most likely metals, but perhaps you’re early in your career and not yet an expert in the instrumental techniques. You’ve already found out that thermal ionization MS (TIMS) and multi-collector ICP-MS (MC-ICP-MS) are the likely techniques of choice, but which should you choose? I work for Isotopx, a company the ...

Analyzing sulfur in soil and sediment with handheld XRF
Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory
ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
