We manage the on demand analyses through our trusted analysis centers delivering the results with our expert interpretation.
DSC is a technique used to characterize the thermal behavior (crystallization/melting) associated to any phase changes in materials.
We apply our knowledge and vast experience to determine thermal properties in foods, cosmetics, pharmaceuticals, etc. with a wide variety of methods such as:
- Melting / Crystallization profile
- Crystallization, gelation, glass transition and melting temperatures
- Enthalpies related to endothermic and exothermic processes (Melting/Crystallization)
- Isothermal analysis (same temperature as a function of time) to determine induction time of crystallization
- Polymorphic identification
- Raw materials degree of purity
- Temperature of oil oxidation
Thermal stability and reversibility
Microscopy is one of the most common techniques used for the characterization of microstructures. It is used to evaluate the shape, size and distribution of crystal structures, making it a powerful and versatile tool for crystal characterization. We offer a wide variety of microscopic analyzes and services of light and polarized light microscopy (PLM) with high experience in the experimental design, preparation and handling of samples to obtain:
- a) Crystal morphological characteristics
- b) Droplet sizes in emulsions
- c) Crystal sizes
- d) Crystal count
- e) Particle size analysis
- f) Cooling/melting effects (slow, fast or quench) in shape, size and number of crystals
- g) Time effect (isothermal evaluation)
- e) Effect of different storage conditions
The dispersion of solids in a liquid causes changes in the viscosity of the solution. However, when the solid particles interact with each other, it causes the formation of three-dimensional networks that grants the material particular mechanical properties with solid and liquid characteristics (viscoelasticity), which can be characterized by:
- Flow curves
- Viscosity as function of temperature
- Zero shear viscosity
- Creep and recovery (Thixotropy evaluation)
- Yield stress
- Gelation and flow temperature
- Strain sweeps
- Frequency sweeps
- Temperature sweep and thermoreversibility
- Linear viscoelastic region (LVR) determination
- Pre-nucleation events (prior to crystallization)
The viscoelastic measurements can be broken down in components such as elastic, viscous and complex modulus (G’, G”, G*) ,phase angle, tan delta etc.
Texture analyzes are performed using compression or stress methods to determine physical mechanical properties of materials that correlate to the human senses. We offer texture test design services, characterization of raw materials and finished products, as well as interpretation of data on texture characteristics such as:
- Hardness
- Fracture
- Elasticity
- Stickiness
- Texture Profile Analysis (TPA)
- Rubberness
- Adhesiveness
- Chewiness
- Cohesiveness
- Sponginess
Solid Phase Content through nuclear magnetic resonance (NMR) is one of the techniques widely used to characterize the crystallization of materials. In this test, the electromagnetic response of the sample to a magnetic pulse is measured where the rate of signal decay for solids is different from the liquids. We use this test for:
- Quality control
- Melting profiles
- Isothermal crystallization rates
Degree of solubilization
The ordering of molecules in a crystal structure produces a unique diffraction pattern when the material is exposed to X-rays. This technique has been used to characterize and identify molecular structures in the solid state.We offer analysis management and interpretation of X-ray diffraction patterns for the determination of crystal types in a wide variety of materials.
We have other analysis on demand such as:
- Compositional through GC-MS, FTIR
- Oxidation stability through Rancimat, TGA, DSC
- Particle size and distribution
- Nutrient Facts
- Enzymatic essays
- Superficial tension
- Microbiological
- Water activity
- Accelerated shelf life prediction
