UHPLC Techniques Speed Analysis of Herbicides

  
  
  
  
  
  
herbicide analysis hplc

I recently received an email notifying me of a newly released herbicide method featuring the use of our latest UHPLC system (Thermo Scientific Vanquish UHPLC system) and one of our solid-core UHPLC columns (Thermo Scientific Accucore Vanquish C18 1.5 μm UHPLC column), and realized it has been a quite sometime since I shared an herbicide application on this blog. So, here goes!

analysis of pesticide residues GC–MS

I am so pleased to offer you this new 52-page interactive e-book, developed by LCGC, on the advances in the analysis of pesticide residues using gas chromatography–mass spectrometry (GC–MS) methods.

HPLC Speeds Determination of Paraquat and Diquat in Water

  
  
  
  
  
  
HPLC automated herbicide analysis

We recently released this fast and sensitive HPLC method for the determination of the agricultural herbicides paraquat and diquat in environmental waters that takes less than 10 mins and, in addition, offers the advantages of full automation, the absence of operator influence, time savings, and strict process control!

Analysis of Endocrine Disruptors

Endocrine disruptors are chemicals that alter the human and animal endocrine system resulting in adverse health impacts and include pesticides such as desethyl atrazine, herbicides simazine and diuron, and the chemical bisphenol A used in the production of plastics and resins. Regulatory bodies around the world are regulating these chemicals in the enivornment particular water supplies for drinking. (All links go to regulatory body webpages.)

Ion Chromatography: Selecting the Best Column for your Analysis

I just received my copy of our free Separated by Experience enewsletter (link to subscription form) and saw this great article on how to select the latest and best ion chromatography (IC) analytical column for your application and thought it would be a great help to our customers!

Chromatography Environmental Application Compendiums

  
  
  
  
  
  
drinking water, groundwater, and wastewater analysis

One of the critical global issues of the day is the quality of our water supply. Environmental scientists around the globe are challenged in their attempts to monitor impurities in drinking water, ground water, and wastewater at trace levels based on regulations established by the U.S. Environmental Protection Agency and other similar institutions around the world.

HPLC Columns Improve Analysis of Triazine Herbicides

  
  
  
  
  
  
triazine herbicides chromatography analysis

Soon after releasing our latest solid-core HPLC columns (Thermo Scientific Accucore HPLC columns), our application chemists have been busy comparing the performance of these columns with conventional HPLC columns. And, the new columns results are showing significant performance improvements as compared to traditional columns in a number of applications under the same chromatographic conditions with no changes in system configuration.

This blog post is about one such improved application, the HPLC analysis of triazine herbicides. The triazine class of compounds includes simazine, simetryn, atrazine, prometon, ametryn, propazine and prometryn.

As per the U.S. EPA, triazine herbicides are toxic as they can cause neuroendocrine and endocrine-related health problems and cancer (link to U.S. EPA Cumulative Triazine Risk Assessment document PDF). Indeed, these herbicides have been banned in Europe but not in the United States.



ASE & LC-MS: Extraction and Separation of Atrazine

  
  
  
  
  
  
atrazine extraction ASE LC MS analysis

The herbicide Atrazine was recently featured in a research study at University of California at Berkeley, and the reporting story--Pesticide atrazine can turn male frogs into females--stated that 75% of frogs exposed to Atrazine were chemically emasculated, and 1 in 10 was turned into a female!
