Chromatography Standards
EPA 8260 Calibration Mix 2, Analytical Standard, 2,000 μg/mL Each Component in Methanol: Water (19:1), MilliporeSigma™ Supelco™
EPA 8260 Calibration Mix 2 is utilized for identifying and quantifying volatile organic compounds on the EPA's Appendix VIII and Appendix IX lists in solid wastes and groundwater at active hazardous treatment, storage, and disposal sites. The pre-requisite of EPA 8260 method is the use of gas chromatography with a selective detector or gas chromatography/mass spectrometry.
PESTANAL™ Saflufenacil, MilliporeSigma™ Supelco™
Saflufenacil is a new pyrimidinedione herbicide registered for the preplant burndown and preemergence use in various agronomic crops.
PESTANAL™ Ethofumesate-2-keto, MilliporeSigma™ Supelco™
Ethofumesate-2-keto is a metabolite of the herbicide, ethofumesate used for the control of weeds in strawberry and beet crops. It inhibits the growth of meristems, retards cellular division and limits the formation of cuticules.
PESTANAL™ Metamitron, MilliporeSigma™ Supelco™
Metamitron is a 1,2,4-triazine herbicide, which is yellow crystalline in nature and can easily degrade in soil to form stable metabolites. It can be prepared via reaction of N-acetyl-benzylhydrazone with hydroxylamine in the presence of potassium hydroxide in pyridine.
