Wet Chemistry

The laboratory has a great deal of formulation and analytical chemistry experience together with the associated equipment which is applied for characterising chemicals and materials:-

• Deformulation
• Formulation or tailored chemical preparation
• Determination of hazardous and problematic substances in a formulation and the appropriate chemicals Health and Safety advice
• Reformulation to generate improved performance or properties
• Routine chemical and materials analysis.

The laboratory provides a range of bench based analytical services, some of which have been ISO17025 (UKAS) accredited:-

• Titration and titrimetric techniques
• Digestion techniques, such as acid digestion of metals, or bespoke ones designed to separate out specific chemical states or compounds.
• Moisture or water content by Carl Fischer
• pH
• Conductivity
• Solvent extraction, separation and extraction of organics forFTIR identification.
• Carbon contents of steels etc. can be measured using a furnace/non aqueous titration technique.

These methods are often used in conjunction with the diverse analytical instrumentation at the laboratory:- AAS, XRF, FTIR, HPLC, GC, UV / Vis, SEM/ EDX, XPS, SIMS and AES.

Sample Preparation

• Extensive range of laboratory, sample treatment, process modelling and sample preparation facilities are available in our laboratories:-
  • Ovens and furnaces
  • Balances and microbalances
  • Sample preparation equipment
  • Metallurgical and other microscopes
  • Polishing and cross-sectioning
  • Fume cupboards & wet chemical preparation
  • Ball Milling

Particle Size Analysis

• Particle sizes of powders separated using vibration sieve sizing.
• Particle size and size distribution measurement by Sedigraph sedimantation techniques.
• Particle analysis by Optical microscopy, SEM and Image Analysis.

Atmospheric Monitoring

• Analysis of atmospheres for organic, inorganic and particulate materials.

Vacuum Leak Detection

• Leak testing of vacuum equipment – Edwards High Vacuum Leak Tester.

Gas Analysis
