Eichrom continues its tradition of being your "time saver" by introducing its Vacuum Box System and extraction cartridge line. By employing vacuum in our already advanced separation methods, analysis time can easily be cut in half over traditional gravity flow Eichrom columns. Customer comments and research in our Rad-lab indicate the same consistently high yields for actinides and strontium as with our conventional columns. Chromatography is improved with the new cartridges that use our smaller 'S' grade resin beads. Another advantage of the cartridge design is the ability to stack two together for tandem separations. Many of our actinide procedures use a common load solution that passes through two resins, for example UTEVA and TRU Resin in our ACW03 method. Using the Luer connections, the cartridges can easily be stacked during sample loading and initial rinse steps and then be separated for final analyte stripping. For sample loading to our cartridges, a standard syringe barrel is recommended, although many reservoirs with a male Luer connection can be used. The cartridges are connected to the vacuum box by two disposable tips. The white inner tip provides an excellent seal with the cartridge and the yellow outer tip provides support. As with our columns, each cartridge is labeled with an identifying lot number. In addition to Sr, TEVA, TRU and UTEVA cartridges currently in stock, our other resins are available by special order in the cartridge format. Though inventory is limited on the Vacuum Box at this introductory stage, we are now accepting orders. Please inquire for an up to date delivery schedule when placing your order and refer to the appropriate part number.
