Health Ranger science lab tour: How pesticides are tested with liquid chromatography and mass spec instruments
01/29/2018 // Mike Adams // Views

If you've ever wanted to know exactly how pesticides and other food contaminants are tested in a real science laboratory, you'll want to watch this video filmed at CWC Labs. Pardon the mess in the video, but as I explain, real science often looks cluttered in an actual laboratory.

In this six-minute video, I explain how liquid chromatography works in combination with mass spectrometry to detect and quantify targeted molecules such as pesticides. This same technique can also be used to detect hormone disruptors, plasticizer chemicals and many other chemicals.

The liquid chromatography separates chemicals by time, where the mass spectrometry instrument identifies molecules by mass. Every molecule, of course, has a specific mass that's derived by adding up the individual masses of the elements found in the molecule. (Molecules are made of elements that are connected in various configurations.)

I filmed this video at CWC Labs, and as you'll see, we're currently running both a "single quad" mass spec instrument and a mass spec time-of-flight instrument, both connected to their own "LC stacks" (liquid chromatography front-ends). These are the instruments we're using to analyze pesticides and other chemicals in off-the-shelf foods. Our goal is to release pesticide testing results for 1,000 off-the-shelf foods and supplements before the end of 2018.

To stay informed on the results as we release them, keep reading Natural News.

Mike Adams (aka the "Health Ranger") is the founding editor of, a best selling author (#1 best selling science book on called "Food Forensics"), an environmental scientist, a patent holder for a cesium radioactive isotope elimination invention, a multiple award winner for outstanding journalism, a science news publisher and influential commentator on topics ranging from science and medicine to culture and politics.

Mike Adams also serves as the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.
