Titer, Cloud & Melting Point, Winterization, Nucleation, Cold Test

Phase Technology is acknowledged worldwide as the leading manufacturer of high precision, user friendly phase detection analyzers and as a partner that you can rely on for problem solving, innovation and outstanding service.  

Our staffThe design of our analyzers is based on the detection of light scatter caused by phase transitions.  The usefulness of our detection device in characterizing low temperature properties such as freezing, cloud and pour points of petroleum products has been well established.  Applications in the Food Industry include many industry standard test methods approved by the American Oil Chemist Society (AOCS), the Association of Official Analytical Chemists (AOAC).

Our NK series of analyzers can be configured to perform tests such as Titer, cloud and melting points, winterization, nucleation and cold properties of oils and fats.  Please contact us for details.

Key Merits of Our Detection Device

Accuracy and precision achieved through state-of-the-art optics and temperature controls.  Test conditions are reproduced in an exacting manner and human judgement is completely removed; as such, phase transition temperatures can be determined with extremely high precision and without preconceived human biases.
 

Analysis speed through automation and intelligent software.  A good understanding on the subject of phase behavior is critical to the success of the design.  Typical analyst time requirement is in the range of 30 seconds and total test elapse time is in the range of  several minutes.
 

Beyond the detection of phase transition temperatures, the apparatus is capable of providing additional information such as the relative extent of phase separation.  This could be useful in indicating the extent of melting, crystallization or immiscibility at different temperatures.
 

The design can yield further information related to flow resistance.  In this case, a fixed amount of  inert gas is pulsed onto the sample surface and the extent of induced movement is quantified.  This technique is useful in characterizing the viscous behavior and gel strength of the specimens under study.
 

Compact instrumental dimensions occupying only 10” of bench width.
 
Small sample size: approximately 150 microliters.
