Enviro-Clean® Push-Thru Glyphosate Purification Cartridges
Water and vegetation/fruits/swabs and other non-soil samples extracted with water are simply pushed through the Glyphosate Purification Cartridge to ultimately remove unwanted matrix that can lead to significant suppression and loss of ionization with glyphosate.
For each sample, take a disposable syringe, remove the plunger, and attach the glyphosate cartridge to the leur lock end. Decant ~3mL of the supernatant into the back of the syringe/cartridge combo. Using the plunger removed earlier, push the sample through the cartridge into a corresponding clean tube. The extract is then saved and sent to derivatization and instrumental analysis.
