Using RGS® Rapid Guide Screw For Precise Motion In New Sample Digestion System Is A Smart Move

New, technologically advanced devices are constantly being developed for use in environmental laboratories. Generally speaking, their primary benefits lie in reduced analysis time, increased accuracy, and greater reliability.

However, it's not often that a device comes along capable of reducing analysis time by over 87 percent: DEENA is the exception. A fully automated sample digestion system for mercury and metals sample preparation, DEENA helps alleviate the bulk of manual sample preparation while greatly reducing the errors associated with sample handling. With less time devoted to sample preparation, laboratory personnel are free to perform other duties with the peace of mind that DEENA will provide consistent data in a clean, safe and timely fashion.

In addition to dispensing reagents and heating the samples, DEENA – essentially an X-Y-Z robot - prepares calibration and spike standards, shakes the samples, inspects their color, adjusts the sample volumes after the digestion process, and records every step taken in the process.

Steve Gunther, a product manager with Thomas Cain, was instrumental in the design of DEENA; in fact, he served in a design consulting role for the project. In a previous position, with a leader in sample handling and sample introduction equipment for elemental analysis, Gunther had become familiar with Hollis, N.H.-based Kerk Motion Products, Inc., one of the world's largest exclusive manufacturers of non-ball lead screws.
