Formulations, measurements and solutions for industry

Measurements


Do you require a specific technique to characterise your system?

Are you in need of additional laboratory facilities in order to meet a deadline?

 

Whatever your need, Formumetrics has a vast array of specialist instrumentation providing valuable information on a wide range of colloid and interface related problems. In addition to our own equipment, we also have access to a whole host of other techniques.

Rheological Measurements

 
 

Rheology is concerned with the deformation and flow of materials. Rheological measurements allow the microstructure of a material to be probed. Experiments can be conducted to simulate production and application processes.

Techniques include:
Viscosity profiles; Creep recovery; Oscillatory rheology; measurements conducted at high temperature or high pressure; simple U-tube viscometry

 

 

Particle Sizing and Size Distribution

 
 

The choice of technique employed for measuring particle size and size distribution is highly dependent on the nature of the system under investigation.

Techniques include: 
Photon Correlation Spectroscopy (PCS) with variable/multi-angle; Static Light Scattering; Laser Diffraction; Focused Beam Reflectance Method; Electron Microscopy and EDX.

 

Structural Properties

 
 

In addition to the size and size distribution of a sample, there are various other properties of interest that have a significant influence on the potential end use.

Techniques include:
Surface area by multipoint BET; micropore analysis; optical microscopy with crossed polars and/or hot stage ; confocal and atomic force microscopy; X-ray scattering (including small angle); Pulse Field Gradient Nuclear Magnetic Resonance; Magnetic Resonance Imaging.

 

Electrochemical Properties of Surfaces

 
 

The surface charge of components within a formulation can play a major role in the overall behaviour of the system.

Techniques include:
Laser Doppler Electrophoresis; streaming potential determination and particle surface charge by conductimetric/potentiometric titrations; dynamic mobility and zeta potential in concentrated aqueous and non-aqueous dispersions using acoustophoresis.

 

Interfacial Measurements

 
 

The behaviour at the interface of two phases can determine the stability of the system produced and the wetting, adsorption, absorption, spreading and spraying properties that the system will possess.

Techniques include:

Ring and plate tensiometry for surface tension, interfacial tension and Washburn measurements, and automatic titration for rapid critical micelle concentration determination; drop shape analysing for contact angle; bubble pressure tensiometry.

 

Formulation

 
 

Formumetrics has extensive background knowledge in the preparation of many types of colloidal systems including: well-characterised, low polydispersity polymer lattices, silica particles and metal sols; novel dispersions such as microgels and particles with magnetic or specified electrochemical properties; surfactant and polymer systems for the production of stable emulsions, foams or thin films. Using our Formulaction Turbiscan, we can quantify the stability of systems, for both analysis and quality control purposes.

 

Other Capabilities

 

Via our external partner network, Formumetrics also has access to the following: Gas Chromatography Mass Spectroscopy (GCMS); High Performance Liquid Chromatography (HPLC); Differential Scanning Calorimetry (DSC); Thermogravimetric Analysis (TGA); Small Angle Neutron Scattering (SANS); X-ray crystallography; mass spectroscopy and analytical NMR. Other analytical techniques may also be available.
