Designed for use in all QuEChERS methods for pesticides in fruits and vegetables, including the original unbuffered method, AOAC 2007.
Additionally, the scientific basis for setting acceptable residual levels and the development of analytical procedures capable of detecting very low levels of target compounds needs to be understood.
Certificate of Analysis includes concentration of TPH, and certified concentrations of BTEX and individual aromatics.
Prepared by flooding the surface of the plate with a liquid culture or suspension of the bacterium, pipetting off the excess inoculum and incubating the plate.
Use to verify the retention time for each compound normally included in a blood alcohol test, and to verify that the compounds are resolved from and do not interfere with one another.
Medium is allowed to set with the tube in the upright position, providing a flat surface at the top of the medium. serial dilution ppt.
