This newly developed furnace/sensor combination is the perfect solution for long-term stability and durability in the most demanding application environments. The 6th generation of bottom-bonded, surface stabilized sensors represents more than two decades of innovative technology and provides superior results in industry standard qualification tests. For example, the indium height to width ratio is improved to 19.5 mW/°C and higher than 155 mW/°C when applying data optimization. Taking all this into account, it is quite evident that the METTLER TOLEDO DSC sensors combine a number of characteristics that are unattainable with conventional sensors used in other instruments.
The investigation of very small to very large sample volumes requires variation of heating rates, crucible types and method gas to properly analyze important material parameters or transitions. The unique built-in FlexCal® technology automatically applies the correct calibration parameters to match the specified heating rate, method gas and crucible type, thus eliminating the worry associated with choosing a specific calibration between experiments. This results in faster measurements as the user does not need to repeat calibration measurements for every change of a measurement parameter as is the case with ordinary DSC instruments.
The DSC 3+ is operated by the new version 14.0 STARe Thermal Analysis software with the single frequency modulated temperature technique, alternating DSC (ADSC), included and the advanced multi-frequency modulated technique TOPEM® available as an option. These techniques offer programming and evaluation possibilities and are especially useful for the separation of overlapping effects and accurate heat capacity determination. Thanks to the versatile modularity of the DSC system, each instrument can be configured according to the requirements of its intended use. Should requirements change after installation, the instrument can be upgraded as needed. This protects the initial investment. Among these available options is the combination of the DSC with a microscope for visual inspection of thermal effects or the usage of a photo calorimetry accessory to study UV-induced curing reactions.
All this makes the DSC 3+ the first choice for users that need high performance combined with versatile modularity and flexible calibration.
Versatile New Simultaneous Thermal Analyzer
The TGA/DSC 3+ features the latest XP micro- and XPU ultra-microbalances from the world-wide leader in laboratory weighing solutions. In the last two decades, METTLER TOLEDO has proudly provided the only thermogravimetric analyzer on the market that can measure up to 50 million resolution points continuously down to 0.1 µg for a 5 gram sample weight. This delivers a true dynamic range which corresponds to the maximum load of the balance and enables a wider variety of sample types to be measured in regards to mass and density. The internal calibration weights, which are used for a fully automatic motorized self-adjustment, ensure that the balance always delivers accurate and reliable results. Since no user action is required, one can never forget to calibrate the balance. In an important industry standard qualification test, the Minimum Weight determination also takes the environment in which a balance is located into account when describing the instrument performance and deciding on the appropriate starting mass for the sample.
The thermo-balance installed in the TGA/DSC 3+ typically delivers repeatability at least two times better than other thermogravimetric analyzers. The improved thermostating of the balance contributes to excellent weighing performance and precise temperature control, even when positioned adjacent to a furnace operating at very high temperatures. This guarantees reproducible results independent from changing environmental conditions in the workplace. The TGA/DSC 3+ is now available with various TGA, DTA and DSC sensors with optimized balance beams which offer better baseline quality, reliable weighing and simultaneous heat flow results at temperatures from ambient to 1100 °C or 1600 °C. This allows for complete thermal analysis in a single-step process and makes a wider application range possible. Built-in user selectable automatic buoyancy compensation eliminates the need for time-consuming baseline measurements.
Thanks to the versatile modularity of the system, each instrument can be configured according to the requirements of its intended use. Should requirements change after installation, the instrument can be upgraded as needed. This protects the initial investment. Among those options available are various interfaces for hyphenated techniques like MS, FTIR, GC/MS or a sorption accessory. All systems for evolved gas analysis (EGA) can be operated together with the sample robot for the automatic analysis of multiple samples.
