A newly opened lab can now detect microscopic levels of the herbicide most commonly used in Monsanto’s RoundUp — glyphosate — in food and soil samples from all over the world.
Anresco Laboratories in San Francisco just launched and they are using an innovative way to test for pesticide residues. Utilizing a regulatory recognized LC/MS/MS method, available to both non-governmental organizations (NGOs) and commercial companies, Anresco is able to find glyphosate in levels much lower than the standard, ‘high detection’ test rate of 20 parts per billion (ppb) and above.
LC/MS/MS, or liquid chromatography tandem mass spectrometry, is considered the gold standard for both quantification and semi-quantitative screening of food contaminants, such as pesticide residues. This is meaningful because the technology allows the lab to test for levels as low as 5 ppb, and in some cases, even lower. With many food and soil samples, LC/MS/MS allows for detection and quantification down to 2 ng/g with recoveries between 70 and 90 percent. This translates to 2 nanograms per billion, or comparatively, like finding a needle in a haystack if the needle was a blade of grass and the haystack was an entire solar system.
