Differential Scanning Calorimetry (DSC) measures heat effects associated with phase transitions and chemical reactions as a function of temperature.
The Zetasizer uses laser technology to measure both size and zeta-potential. The size measurement is limited to 0.6nm to 6 microns and uses reflective light and Brownian motion. Our instrument uses a 633nm red laser fitted to do both front and back light scatter. The instrument is equipped to assist with specimen quality evaluation, automatic charts, data processing, and various report formats for the user.
Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. The Q50 features a vertical beam balance design (sample capacity: 1000 mg) that supports precise TGA (balance sensitivity: 0.1 µg) measurements.
Dynamic Mechanical Analysis (DMA) measures mechanical properties of samples. Its principal uses include measurement of a material's Young's modulus or viscoelastic properties as a function of temperature (or time). Testing can be performed in either tensile or cantilever bending geometries.
Differential Thermal Analyzer (DTA) uses a two-pan system to measure the heat flux difference between an empty pan (or one with a reference material) against the temperature of a sample of specific weight. The DTA-50 system uses temperatures in the range between room temperature and around 1400 oC to determine thermal transitions such as glass transitions, crystallization, phase changes, melting, stability, cure kinetics, etc. While it is not as sensitive as a differential scanning calorimetry (DSC), it is more versatile for harder materials, as our DSC system cannot operate above 400oC. The DTA-50 instrument is calibrated to 1100oC for accuracy.
