Differential thermal analysis.

DSC 204 F1 Phoenix® – Differential Scanning Calorimeter.

The versatile Premium Differential Scanning Calorimeter, DSC 204 F1 Phoenix®, fascinates with its unique concept: all essential operational components are integrated into the instrument and optional add-ons can be installed anytime on site.

The DSC measuring cell consists of a cylindrical high-conductivity silver block with an embedded heating coil for broad thermal symmetry (3D symmetry) in the sample chamber, the cooling ports for liquid nitrogen or compressed air cooling and a cooling ring for connection of the intracooler (also with simultaneous liquid nitrogen cooling). The gas-tight construction and integrated mass flow controllers for the purge and protective gases allow coupling to an FTIR or MS for gas analysis.

Exchangeable sensors are tailored to their tasks:

  • With its disk-shaped silver carrier plate and supersensitive thermosensors of nickel-chromium constantan, the Tau-sensor offers a high level of calorimetric sensitivity along with extremely short signal time constants of only 0.6 seconds, which guarantees good separation of overlapping thermal effects.
  • The µ-sensor stands out for its high level of calorimetric sensitivity, never before achieved with a Differential Scanning Calorimeter, DSC. For example, it is extremely well suited for pharmaceutical applications with small sample weights.

Important hardware extensions like the automatic sample changer (ASC) for up to 64 sample and reference crucibles, the UV-extension for photocalorimetry and software features such as BeFlat® for an optimized baseline or the optional temperature modulation of the DSC signal (TM-DSC) make the DSC 204 F1 Phoenix® the most versatile DSC system for research & development, quality assurance, failure analysis and process optimization on the market today.


Photo-DSC 204 F1 Phoenix® – Differential Photocalorimeter for UV curing and more.

The main advantage of light-curing systems is their fast reaction time. Monomer solutions which are mostly free of solvents can be cured within only a few seconds and already at low temperatures. A combination of thermal and light curing reactions is often applied to dual cure adhesives or paints.

The NETZSCH Photo-DSC 204 F1 Phoenix®, Differential Photocalorimeter, works in the temperature range from  -100°C to 200°C. The Differential Photocalorimetry instrument has a gas-tight measuring cell and the purge gas control is regulated by a mass flow controller (MFC).

 

For our Photo-DSC 204 F1 Phoenix®, Differential Photocalorimetry system, most standard industry or laboratory lamps for cationic or radically curing material systems can be used.

 

For adhesives, we recommend the DELOLUX04 high-pressure mercury lamp (315-500 nm), which can easily be triggered using the Proteus® software.

For paints and inks, we recommend the Photo-DSC (Differential Photocalorimeter) be equipped with an OmniCure® S2000 lamp. The measurement parameters (e.g. exposure time and intensity) can be programmed and monitored by segment via the Proteus® software.

The luminous intensity of the high-pressure mercury lamp can be calibrated with the Radiometer R2000.

 

The modified automatic lid-lifting device of the DSC 204 F1 Phoenix®, Differential Photocalorimeter, guarantees a defined distance between the two light conductors and the sample and reference. This achieves high reproducibility of measurement results.

For your normal DSC analyses above 200°C, a retrofit of the standard lid-lifting device is possible, or the manual lid can also be used without problems.

 

For high sample throughput or for repeat measurements, use of our Automatic Sample Changer (ASC) for up to 64 samples is recommended.


DSC 204 HP Phoenix® – High-pressure DSC for specific reactions.

With the high-pressure Differential Scanning Calorimeter, DSC 204 HP Phoenix®, thermal effects in a sample can be analyzed in the pressure range from vacuum to 15 MPa (150 bar) and at temperatures from -150°C to 600°C, depending on the type of gas.

The sample chamber atmosphere can be static or dynamic. The electronic pressure monitor and control, along with exact regulation of the purge gas flow, provide for excellent accuracy and reproducibility of the measurement results.

The proven CC 200 L for liquid nitrogen cooling is available for the low-temperature range.

The safety of the high-pressure DSC system has been certified through design tests and is guaranteed during operation by the appropriate safety components.
