TGA

Perkin Elmer TGA 8000™

The TGA 8000 gives you the confidence that comes with total control of your sample atmosphere, both temperature and gas. Our furnace's temperature control system creates a wide effective temperature range – from subambient to 1,200 °C. The system delivers heating rates from 0.1 °C to 500 °C/minute to address the widest range of applications, and its low mass and forced-air cooling allow it to cool quickly for fast sample turnaround. For sample gas environment, the system provides two integral mass-flow controllers for balance and sample purge. Built-in gas switching from Pyris™ software makes switching easy, while optional gas mixing allows the blending of up to three reaction gases, with delivery direct to the sample area.

TOC

Shimadzu TOC-L

The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide. While providing an ultra wide range of 4 μg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 μg/L through coordination with NDIR. This is the highest level of detection sensitivity available with the combustion catalytic oxidation method.

In addition, the combustion catalytic oxidation method makes it possible to efficiently oxidize not only easily-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds.

Ball Mill

Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times.

The PM 200 is a convenient benchtop model with 2 grinding stations.
