Charged Additives Save Pesticides and the Environment

Posted by Betsey Seibel on Mon, Oct 03, 2016 @ 11:34 AM

The term “spring water” brings to mind a clear, mountain stream.  But “spring” or “bounce” in water actually is a safeguard for plant leaves.  Liquid droplets have elasticity and bounce off of leaves.  This “water bounce” protects plants because plants drink in water from their roots, not from leaves.  If water lingers too long on leaves, then mold builds up and decays the plant. 

However, this protective “water bounce” from Mother Nature has negative side effects for farmers. 

Around the world, farmers commonly spray their fields with pesticides.  The innate “bounciness” of liquid droplets forces a considerable amount of the pesticide off of the plants; only a paltry amount of what is sprayed actually sticks. Therefore, farmers must use a lot more pesticide than they need.  And because farmers have to use so much spray to get the desired pesticide benefits, surplus pesticide chemicals seep off plants and end up polluting land and waterways.

Total Solution for Food and Environmental Laboratory Testing

Posted by Teledyne Tekmar on Mon, Jun 03, 2013 @ 09:24 PM

Over the past few months, Ab Sciex hosted a technical talk with invited guest from Teledyne Tekmar, Phenomenex, and Gerstel on driving innovation, “Better Ideas for the Modern Food and Environmental Testing Laboratory”. The goal of this workshop was to show that collectively these companies could create a total solution for food and environmental laboratory testing.  It, also, served as a forum to talk about pertinent issues and challenges in regards to food testing.  Teledyne Tekmar was privileged to introduce the new AutoMate-Q40 a revolutionary system specifically designed and optimized to automate the QuEChERS sample preparation workflow. The AutoMate-Q40 system automates the following sampler preparation functions:
