The Fusion Cell delivers the most absolute heat flow measurement possible. Additionally, lengthy pre- and post-test manipulations such as baseline subtractions or de-smearing routines required by competitive designs are never necessary.

Tzero® Technology

Traditionally, DSC heat flow measurements have been based on the same principle that ASSUMES contributions by the sample and reference sensor to the total measured heat flow simply cancel each other out. If this assumption was true, all DSC’s would have perfectly flat baselines. In reality, they do not. The fact is that each sensor’s resistance and capacitance (ability to store energy) produce imbalances in the heat flow, resulting in deviations from baseline flatness and impaired resolution and sensitivity. ONLY TA Instruments, with patented Tzero Technology, can measure this imbalance. Tzero Technology eliminates complicated pre- and post-test manipulations, such as baseline subtraction, deconvolution or other mathematical treatments competitive designs must use to improve baseline performance, sensitivity and resolution.

Patented Tzero Technology measures the resistance and capacitance of the sensors and utilizes these values in the four-term heat flow equation to give the most accurate real-time determination of heat flow available on any DSC. TA engineers have taken this one step further by also including the contributions of the DSC pans. This Advanced Tzero technology, T4P heat flow, provides the sharpest resolution, the highest sensitivity and allows for the measurement of heat capacity in a single run!

Features and Benefits:

• Flattest baselines available of any DSC on the market, resulting in the purest data without manipulation or subtraction.
• Highest resolution and sensitivity, without ever needing lengthy pre- and post-test manipulations as required by competitive designs.
• Direct measurement of heat capacity delivering the most uniform and accurate heat flow to and from the sample.
• By improving every aspect of performance, the Discovery DSC delivers data the user can trust, in all applications, all the time.

Modulated DSC

Modulated DSC Gain confidence in data interpretation with the help of MDSC®. Through deconvolution of the Total Heat Flow signal, events such as a glass transition masked under an evaporation peak, or the simultaneous occurrence of a cold crystallization with a melt, are easily revealed.

In TA’s patented MDSC*, a sinusoidal temperature oscillation is overlaid on the traditional linear ramp. The net effect is that heat flow can be measured simultaneously with, and independently of, changes in heat capacity. The Total Heat Flow signal contains the sum of all thermal transitions, just as in standard DSC.

Modulated DSC separates the Total Heat Flow into the Reversing and Non-Reversing Heat Flow signals. The Reversing Heat Flow, comprised of the heat capacity component, contains glass transition and melting transitions. The Non-Reversing Heat Flow, the kinetic component, contains events like curing, volatilization, melting, and decomposition. TA invented MDSC and understands it like no other company. Modulated DSC is a standard feature on EVERY Discovery DSC model.

Benefits of MDSC include:

• Separation of complex and overlapping transitions into more easily interpreted components.
• Increased sensitivity for detecting weak transitions.
• Increased resolution without loss of sensitivity.
• More accurate measurement of polymer crystallinity.
• Direct measurement of heat capacity.

Discovery Liquid Nitrogen Pump Accessory (LN Pump)

The LN pump provides the highest performance and greatest flexibility in cooling for the Discovery DSC. It facilitates the lowest operational temperature (to -180 °C), greatest cooling rate capacity (to 140 °C/min), fastest sub-ambient equilibration times, and an upper temperature limit of 550°C. Operating at ambient pressure, the LN Pump uses liquid nitrogen efficiently, thus reducing operating costs. It includes a 50-liter Dewar with auto-fill capability which allows the LN Pump to be automatically refilled from a larger source, even during a DSC experiment, for continuous DSC operation with no disruption.

Tzero Pans

Tzero high-performance pans and lids are designed to maximize pan flatness and sample contact. Coupled with the unparalleled flatness and uniformity of the Fusion Cell™ sensor, the Tzero pans and lids provide the most direct, uniform heat flow path from the sample to the sensor. These pans are tolerant of many sample forms and are designed with lids that conform to the top of irregular specimens, efficiently transferring heat to and from the entire sample. Competitive pan designs that have non-flat bases are unable to achieve appropriate thermal contact with solid specimens. Fabricated using advanced technology and to extremely tight tooling specifications, the Tzero pans offer significant improvements in resolution and repeatability over any other pan design.

Tzero DSC Sample Encapsulation Press

The Tzero press takes sample encapsulation to a higher level of performance and convenience in conventional and hermetic sealing of a wide variety of materials. The press kit includes four die sets for Tzero aluminum and hermetic pans & lids. Optional die sets are available for high-volume DSC pans and Discovery TGA sealed pans. The die sets are magnetically attached with no tools or adjustments required. In addition, each die set is color-coded to the box containing the compatible Tzero or standard aluminum hermetic pans and lids.

Sample Cutting Kit

Samples for testing in the DSC come in all different forms, shapes, and sizes and typically require some type of manipulation before they can be loaded into a DSC pan. The sample cutting kit includes tools that will make it simple and easy to properly prepare samples for the ultimate repeatability and reliability of the results. A pliers-style sample cutter will provide a sample with a clean, flat surface to maximize sample to pan contact. A 4mm hole-punch and hammer will allow film samples to be cut into a consistent size perfect for Tzero pans. This tool kit is designed to help ensure that the high-level performance of the Fusion Cell and the Tzero pans is enhanced with the perfectly prepared sample.

Tzero® Powder Sample Preparation Kit

The task of loading powder samples into Tzero pans is now quicker and easier with the powder sample prep kit. Specifically designed to maximize the performance of Tzero Pans with powdered samples, the kit consists of a non-skid base and a three-part tool precision machined from high quality stainless steel. The lower tool has a precisely designed recess that holds the Tzero pan and supports and protects the bottom of the pan. The upper tool mounts over the pan, forming a funnel which directs the sample into the center of the pan, avoiding undesirable contamination of the outside surfaces of the pan. A steel rod is used to pack the sample firmly into the bottom of the pan, forming a packed layer of the powder while preserving the flatness of the bottom of the Tzero pan. Using this tool you can easily and effectively optimize the results of your DSC measurements of powdered samples.
