The MARS 2 is a microwave acid digestion system that produces an aqueous solution for elemental analysis by ICP, ICP-MS, or AA. Plants, soil, foods, pharmaceuticals, and more can be digested easily, using preloaded methods. For over 30 years, lab technicians have been using MARS systems for sample preparation. With the latest updates to the MARS 2, the process is even easier.
- Industry best 316 stainless steel cavity construction
- Multi layer Teflon® coating applied in proprietary process for superior corrosion resistance
- Non metallic high impact polymer casing
- High capacity integrated exhaust system to remove fumes and assist in cooling vessels
The One Touch® icon on the MARS 2 touchscreen, you’ll be able to choose the sample type from the preinstalled methods. Each method includes the recommended sample size, acid type, and acid volume. The system it will automatically detect the type of vessel you are using, count the vessels, adjust the power accordingly, and perform the digestion for you. It couldn’t be easier.
The MARS 2 uses a series of integrated contactless sensors to provide the most accurate power delivery and temperature measurement. Floor mounted sensors are used to count the number of vessels being processed to determine the correct power at start up. When only preparing a few samples the initial power is greatly reduced while large batches will receive more power. This control is unique to the CEM MARS family and provides the finest control available. A second sensor recognizes the vessel type chosen to make certain it is appropriate for your sample type. Finally, the iWave temperature sensor provides the most accurate contactless temperature control available. This combination gives you the unmatched performance of a MARS system.
MARSXpress and MARSXpress Plus vessels are easy to use three-piece vessels that assemble in seconds, yet are rugged enough for most sample types. MARSXpress vessels, with vent and reseal technology, were patented in 2003 and have been the industry standard since that time. These vessels simultaneously run mixed sample types such as foods, tissues, and cannabis in a single batch. This greatly increases productivity in a lab that has varied sample materials. The 55 ml and 75 ml MARSXpress and the 110 ml MARSXpress Plus can all be run in the MARS 2.
MARS 2, with iWave® temperature sensing technology, has brought tremendous advantages to microwave digestion, including the use of disposable vessel inserts. Vessel inserts offer a convenient way to process samples with little to no vessel cleaning. The choice of insert will depend upon digestion temperature and blank values required, based on the limit of quantification for a particular analysis. For trace metals analysis, it is vital to be aware of any materials coming into contact with the sample, which could contaminate the sample. In general, Teflon® and quartz are considered analytically clean materials for use in nearly any application. Glass, by composition, is higher in certain impurities, which may make it unsuitable for some applications.
The MARS 2 has been extensively tested to provide successful digestions for samples such as food materials, plant and animal tissue, fish tissue, feeds and fertilizers, and many more samples.
