Setaram Instrumentation has just delivered its first SENSYS DSC and TG DSC units worldwide.

The SENSYS thermal analyzers are designed to offer even better performance than its predecessors (DSC 111 and TG DSC 111).

Among its features, SENSYS now includes an automated gas control panel offering gas mixing capabilities.

SENSYS benefits from the exclusive SETARAM "3D sensor inside" technology which is the latest evolution of the Tian-Calvet calorimetric principle and the "key element" of the instrument.

With a tridimensional ("3D") sensor indeed, the sample is almost completely surrounded by rings of thermocouples so that the heat flow emitted from or absorbed by the sample is almost completely measured.

The efficiency ratio of the "3D" sensor i.e. the heat measured by the sensor divided by the total heat involved in a thermal event is about 94% whereas it does not exceed 50% for a plate-DSC "2D" configuration.

By using two identical 3D sensors for the sample and the reference, the symmetrical arrangement of 3D sensors in SENSYS ensures accurate and reproducible specific heat or heat of reaction determinations which are absolutely necessary in the fields of process safety, pharmaceuticals or catalysis for example

Other advantages of SENSYS include:

The temperature range which is the widest on the DSC market:- 120, +830°C with a single furnace.

The absolute calibration: the sensitivity of SENSYS is indeed independent of the sample mass and size, the type of crucible as well as the nature and the flow-rate of the sweeping gas.

With a specific electrical device, long-term calibration can thus be performed over the entire temperature range.

The unequalled modularity: the characteristics of the 3D sensor remain unchanged whatever the configuration of the SENSYS instrument: horizontal DSC, vertical DSC, with an auto-sampler (Robotic DSC), connected to a symmetrical microbalance (TG DSC), coupled to an evolved gas analyzer (EGA) such as Mass Spectrometer, Gas Chromatograph, FT Infrared Spectrophotometer or BET surface area measurement device.

A rotation system makes the change from horizontal to vertical DSC or TG DSC simple, fast and safe for the detector.

A high level of performance in TGA: with the fully symmetrical SENSYS TG DS simultaneous analyzer, the disturbing buoyancy effect is automatically compensated and the base-line drift of the mass variation signal is minimized.

The largest choice of sample containers and accessories on the market: built around two open refractory tubes crossing the furnace from one end to the other, SENSYS offer the largest choice of crucible materials (aluminum, silica, platinum, alumina, graphite) and volumes (from 120 up to 320 µl) as well as of specific accessories such as controlled high-pressure vessels (up to 500 bars at 600°C) or vertical silica reactor for adsorption/desorption studies.

Moreover, the data provided by SENSYS can be analyzed by the AKTSAdvanced Thermokinetics and AKTS-Thermal Safety software in order to predict the thermal behavior of any substance and to determine the kinetic parameters of any reaction.
