Humidity and IdentiPol - Humidity Generator and Controller
The Triton Technology Humidity Generator and Controller is a unique and flexible solution to deliver an accurate relative humidity for multiple applications.
Gas is pumped through a desiccant built into the instrument. A valve, controlled by a humidity sensor placed at the sample site, is used to divert some gas flow through a water reservoir before being pumped through to the sample. This rapid feedback function ensures that the real humidity at the sample site is the humidity requested. This is a key feature of the Triton Humidity Generator. It should not be confused with lesser humidity controllers.
This outstanding control allows accurate programmable humidity profiles to be set up with the ability to accurately and rapidly ramp humidity up and down as required. When accurate, precise humidity control is required this system has no peers.

85/85 Humidity Chamber
The Triton Technology 85/85 Humidity Chamber is a unique solution to deliver an accurate relative humidity up to 85ºC and up to 85% humidity in a Tritec2000 DMA or a Perkin Elmer DMA 8000. This Chamber also requires the Triton Humidity Generator and Controller and a Recirculator. A simple modification to the DMA drive body cover may also be required for those wishing to routinely reach maximum specification.
Features
• Thermal jacket completely surrounds sample chamber
• Easy conversion to standard DMA use and vice versa
• Utilises the proven feedback control of the Tritec2000 Humidity Generator and Controller unit (humidity sensor incorporated inside the Chamber)
Benefits
• No ‘cold spots’
• Highly stable humidity control
• Rapid set up

IDENTIPOL
: FOR THE QUALITY ASSURANCE OF THERMOPLASTICS
The principle behind this technology is a variant method based on well founded thermal analysis procedures. More specifically, both a thermo dynamic mechanical analysis and a differential thermal analysis of each test sample is produced and is available to build up a distinct 'pattern' of the test material that the system can remember.
As polymers are quite variable in themselves, it is important to produce reference sets based on a good statistical sample of the production material. Only then can the real benefits of the identiPol system become truly apparent.
The success of this unit depends very much on the novel Pat. Pending sample holder and preparation procedure. This allows material in pellet or other forms to be moulded consistently whilst at the same time provides a heat transfer lattice throughout the prepared sample enabling very rapid heat transfer.
This in turn allows for very rapid analysis of the material. As this methodology is not based on optical analytical methodology, no issues arise from using filled materials including carbon black. The result is not affected by these additions.
A full thermal profile which includes relaxation, crystallisations and melts is reduced by mathematical means to a simple statistical probability.
The system can also produce glass transition and an effective melt temperature where these exist. These can be potent evidence when failures or deviations occur in the material entering production.The I

Complete plastics testing in a box!
* 'fit for purpose' in this context means that a tested material compares well thermo mechanically with the original materials used to establish the reference set to which it is being compared.
** It is always recommended that a material or process should utilise more than one technique to aid confirmation of on-going quality. A good 'sister' technique to use alongside the identiPol QA is MFI. Other tests may also be useful.
